SAP Note 496082 - FAQ: Account assignment in purch

This note provides answers to frequently asked questions concerning account assignment in purchasing documents.

List of questions

1. Why is the G/L account for a sales order with non-valuated customer sales order stock different from the account with valuated customer sales order stock?
2. Can I create several assets in the new purchasing transactions at the same time?
3. You create a purchase order with account assignment using Transaction ME22. You enter a material group, from which a G/L account is determined via the valuation class. If you go to a material group that does not determine a G/L account via the valuation class, the system deletes the previous G/L account and prompts you to enter a G/L account. If you cancel the account assignment screen and change back the material group on the item detail screen, the previously determined G/L account is not determined again. Why is that?
4. Is there an easy way of entering the same account assignments for different items in the new Enjoy transactions?
5. Why does the repeat account assignment function not work in the new Enjoy transactions when I create new account assignments in the multiple account assignment?
6. Why does the system generate message KI161 'Cost center does not exist on &' when I change the account assignment of an existing purchase order?  The same thing happens for other account assignment objects (for example, profit center).
7. Can I create assets from within the single account assignment screen?
8. Why does the system not display an account assignment tab page even though I have entered an account assignment category?
9. Why does the system sometimes derive account assignment objects even though the corresponding field on the account assignment tab page is hidden??
10. You create a purchase order with reference to a subcontracting purchase requisition. This purchase requisition was created with an unknown account assignment, that is, account assignment category 'U'. When you change the account assignment category in the purchase order, the system issues error message ME453 'Changing consump. or spec.
11. Why can I not select a valuated goods receipt together with multiple account assignment in a purchase order/purchase requisition?
12. Funds Management is active. Why are the fields EBAN-FISTL, -GEBER, -KBLNR, -GRANT und -FKBER (as in table EKPO) empty?
13. You want to change a purchase order item with account assignment category 'A' which contains a locked asset. The system displays error message AA 334: 'You cannot post to this asset (Asset & & blocked for acquisitions)'.
14. What is the meaning of the indicator for the account assignment screen that I can set in Customizing for Single account assignment/Multiple account assignment?
15. Is there an unknown account assignment for standard purchase orders?
16. You change data in a purchase order item (for example, purchase order value, delivery date, and so on). The system does not check the account assignment again.
17. If you delete all entered account assignment lines in the account assignment screen, the system exits the account assignment tab title and goes to the material data. In addition, the system displays an error message telling you to enter account assignment data for the item in case of an account assignment.
18. Which account assignment categories should I enter in schedule line categories for third-party order processing (CS) and individual purchase order processing (CB)?
19. You subsequently change the material group in a limit purchase order or in a purchase requisition assigned to an account. Even though the new material group is assigned to another G/L account via the valuation class, the system does not redetermine the account assignment of the item. The old G/L account remains.
20. In Customizing, you can set the account assignment fields as mandatory, optional or display fields or as completely hidden fields, depending on the account assignment category. These settings also determine whether or not the system deletes the values of the account assignment fields when you change the account assignment category in a purchase order item.
21. You create a purchase order item assigned to an account with reference to a purchase requisition. You create a second schedule line for this purchase order item with reference to another purchase requisition. The system ignores the account assignment data of the purchase requisition for the second schedule line.
22. Why can I undelete an item in a purchase requisition if the corresponding account assignment data is no longer valid?
23. You create a purchasing document with reference to a reference document. What account assignment data is transferred?

1. Question:
Why is the G/L account for a sales order with non-valuated customer sales order stock different from the account with valuated customer sales order stock?

Answer:

Refer to Note 458270.
--------------------------

1. Question:
Can I create several assets in the new purchasing transactions at the same time?

Answer:

It is possible to create several assets at the same time. However, you must ensure that there are enough account assignment lines for the number of assets you want to create. You can insert additional lines using the copy function.
--------------------------

1. Question:
You create a purchase order with account assignment using Transaction ME22. You enter a material group, from which a G/L account is determined via the valuation class. If you go to a material group that does not determine a G/L account via the valuation class, the system deletes the previous G/L account and prompts you to enter a G/L account. If you cancel the account assignment screen and change back the material group on the item detail screen, the previously determined G/L account is not determined again. Why is that?

Answer:

Unfortunately, we cannot change this system behavior. First, enter any G/L account so that the item is valid. If you then go to the old material group again, the system determines the correct G/L account.
--------------------------

1. Question:
Is there an easy way of entering the same account assignments for different items in the new Enjoy transactions?

Answer:

Ensure that Note 315676 is implemented in your system and follow the procedure described there.
--------------------------

1. Question:
Why does the repeat account assignment function not work in the new Enjoy transactions when I create new account assignments in the multiple account assignment?

Solution:

Use the copy function in the multiple account assignment to create identical account assignment lines. With the repeat account assignment function you can create similar account assignments for different items with the same account assignment category. To do this, proceed as described in question 4.
--------------------------

1. Question:
Why does the system generate message KI161 'Cost center does not exist on &' when I change the account assignment of an existing purchase order?
The same thing happens for other account assignment objects (for example, profit center).

Solution:

Refer to Note 193371.
--------------------------

1. Question:
Can I create assets from within the single account assignment screen?

Solution:

Assets can only be created from the multiple account assignment screen ('Account assignment' tab page).
You can change between single account assignment and multiple account assignment in the 'Account assignment' tab page by clicking the icon in the upper left corner.
--------------------------

1. Question:
Why does the system not display an account assignment tab page even though I have entered an account assignment category?

Solution:

When you have implemented Note 520149, the system only displays the account assignment tab page when you have entered all required information, for example, the company code.
--------------------------

1. Question:
Why does the system sometimes derive account assignment objects even though the corresponding field on the account assignment tab page is hidden??

Solution:

Refer to Note 619203.
--------------------------

1. Question:
You create a purchase order with reference to a subcontracting purchase requisition. This purchase requisition was created with an unknown account assignment, that is, account assignment category 'U'. When you change the account assignment category in the purchase order, the system issues error message ME453 'Changing consump. or spec.

Solution:

Refer to Note 205597.
--------------------------

1. Question:
Why can I not select a valuated goods receipt together with multiple account assignment in a purchase order/purchase requisition?

Solution:

Refer to Note 204252.
--------------------------

1. Question:
Funds Management is active. Why are the fields EBAN-FISTL, -GEBER, -KBLNR, -GRANT und -FKBER (as in table EKPO) empty?

Solution:

The system only fills these fields if the account assignment category is set to 'blank'. If you maintain an account assignment category in the purchasing document, the system transfers the information in these fields to the EBKN table (as in EKKN).
--------------------------

1. Question:
You want to change a purchase order item with account assignment category 'A' which contains a locked asset. The system displays error message AA 334: 'You cannot post to this asset (Asset & & blocked for acquisitions)'.

Solution:

This is standard system design. To change this purchase order item, you have the following two options:

a) If you no longer require the purchase order item with the blocked asset, delete the purchase order item.
b) Otherwise, activate the asset, make the required changes to the purchase order item and then block the asset again.
--------------------------

1. Question:
What is the meaning of the indicator for the account assignment screen that I can set in Customizing for Single account assignment/Multiple account assignment?

Solution:

The indicator determines the account assignment screen that is generally used for maintaining the account assignment of a purchase order item.
For the EnjoySAP transactions, this value is a proposal that you can change in the purchasing document.
For the old transactions, this value is the only value you can use.
--------------------------

1. Question:
Is there an unknown account assignment for standard purchase orders?

Solution:

In general, this is not allowed, and the system displays message ME 069 'Unknown account assignment not assigned for user here'. Service items that you create with item category D (Service) or B (Limit) are an exception in this respect.
--------------------------

1. Question:
You change data in a purchase order item (for example, purchase order value, delivery date, and so on).
etc.). The system does not check the account assignment again.

Solution:

This is standard system design. If the system has already checked the account assignment without errors when you created the purchase order item, it only checks the account assignment again if you change a field that is relevant for the account assignment (for example, quantity, material number, and so on).
If this system response does not meet your requirements, implement the account assignment check in the ME_PROCESS_PO_CUST BAdI. The system calls the BAdI each time the purchase order is changed.
--------------------------

1. Question:
If you delete all entered account assignment lines in the account assignment screen, the system exits the account assignment tab title and goes to the material data. In addition, the system displays an error message telling you to enter account assignment data for the item in case of an account assignment.

Answer:

If you delete all account assignment lines, the system assumes that you do not want to maintain account assignment data.
This is in conflict with the account assignment category and the system issues error message 06436. You can remove the account assignment indicator.
Procedure:
If you want to delete all entered account assignment data, you can simply remove the account assignment category. The system then automatically deletes all account assignment data.
If you only want to change the account assignment data, make the changes in the corresponding account assignment lines and delete the lines you no longer require.
--------------------------

1. Question:
Which account assignment categories should I enter in schedule line categories for third-party order processing (CS) and individual purchase order processing (CB)?

Solution:

See Note 210997.
--------------------------

1. Question:
You subsequently change the material group in a limit purchase order or in a purchase requisition assigned to an account. Even though the new material group is assigned to another G/L account via the valuation class, the system does not determine the account assignment of the item again. The old G/L account remains.

Solution:

See Note 449216.
--------------------------

1. Question:
In Customizing, you can set the account assignment fields as mandatory, optional or display fields or as completely hidden fields, depending on the account assignment category. These settings also determine whether or not the system deletes the values of the account assignment fields when you change the account assignment category in a purchase order item.

Answer:

In MM Customizing, when you maintain the account assignment categories (IMG: Materials Management-> Purchasing -> Account Assignment-> Maintain Account Assignment Categories), you can control the different account assignment fields as follows:
                       Required entry: You must make an entry in the field, otherwise the system displays error message ME 083.

                       Optional entry: You may make an entry in the field.

                       Display: The field is displayed, but it is not ready for input.

                       Hidden: The field is hidden.

For example:
Account assignment category K, the cost center field is optional, the cost center field is filled with value 1000;
you change the account assignment category to P.
Depending on the field settings for the cost center with account assignment category P, the system response is as follows:
                       The cost center is a required entry or an optional entry field: The system transfers the value 1000 for the cost center

                       Displaying the cost center: first, the value 1000 is deleted for the cost center. If the system can determine a value again after you enter the changed account assignment category, this value is transferred.

                       The cost center field is hidden: The system deletes the value 1000 for the cost center.

--------------------------

1. Question:
You create a purchase order item assigned to an account with reference to a purchase requisition. You create a second schedule line for this purchase order item with reference to another purchase requisition. The system ignores the account assignment data of the purchase requisition for the second schedule line.

Solution:

This is standard system design. The system does not create a multiple account assignment in the purchase order item, even if the two referenced purchase requisitions are assigned to different CO objects.
Also refer to Note 47150 for the old transactions and to Notes 422609 and 771045 for the EnjoySAP transactions.
--------------------------

1. Question:
Why can I undelete an item in a purchase requisition, if
the corresponding account assignment data is no longer valid?

Solution:

When you undelete an item in a purchase requisition, the system does not run a new account assignment check. Therefore, the system does not check the account assignment data again.
Nevertheless, errors occur if you try to create a purchase order with reference to this purchase
requisition.
When you undelete an item in a purchase order, however, the system does run
another account assignment check.
--------------------------

1. Question:
You create a purchasing document with reference to a reference document. What account assignment data is transferred?

Solution:

The account assignment data is derived from the reference document.
If you delete the account assignment category and enter it again, a new automatic general ledger account determination occurs.
