Implementing BADI for the transactions VL02 & MM02

Introduction to BADI<?XML:NAMESPACE PREFIX = O />

1. Based on OOPS concept.

2. No access key required.

3. All BADI’s can be seen in a class ‘CL_EXITHANDLER’.

Step 1:

Run the transaction SE24. Under object type put the class name ‘CL_EXITHANDLER’.

Click on display button.

Under this class ‘CL_EXITHANDLER’ select the method ‘GET_INSTANCE’ and double click.

<shape id="_x0000_i1026" style="WIDTH: 292.5pt; HEIGHT: 216.75pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image003.png" o:title=""></imagedata></shape>

Under the method ‘GET_INSTANCE’ put break point on a function module called

‘CALL METHOD CL_EXITHANDLER=>GET_CLASS_NAME_BY_INTERFACE’

<shape id="_x0000_i1027" style="WIDTH: 280.5pt; HEIGHT: 241.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image005.png" o:title=""></imagedata></shape>

<shape id="_x0000_i1028" style="WIDTH: 308.25pt; HEIGHT: 241.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image007.png" o:title=""></imagedata></shape>

Step 2:

Then according to the requirement run the transaction. In this example transaction code is VL02.

Run the transaction VL02. As in 1^st step we have putted a break point, that function module will give all BADI used by the transaction in each screen and activity on the application (VL02).

<shape id="_x0000_i1029" style="WIDTH: 303.75pt; HEIGHT: 228pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image009.png" o:title=""></imagedata></shape>

Under the parameter EXIT_NAME this debugger screen will give all BADI name for each screen.

<shape id="_x0000_i1030" style="WIDTH: 292.5pt; HEIGHT: 234pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image011.png" o:title=""></imagedata></shape>

Each time press F8, you will get all BADI used for the screen. After that system will go for next screen.

BADI NAME: EHS_DG_001

LE_SHP_DELIVERY_PROC

LE_SHP_PRICING

BADI_LAYER

CU_CONFIG_DELEGATION

1^st screen of transaction VL02.

<shape id="_x0000_i1031" style="WIDTH: 290.25pt; HEIGHT: 105.75pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image013.png" o:title=""></imagedata></shape>

Step 3:

Choose your BADI name and you can see the detail in transaction SE18. Lets take a BADI ‘BADI_LAYER’. Click on display button.

<shape id="_x0000_i1032" style="WIDTH: 273pt; HEIGHT: 140.25pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image015.png" o:title=""></imagedata></shape>

Press F8 to get the details of the corresponding BADI.

<shape id="_x0000_i1033" style="WIDTH: 291pt; HEIGHT: 206.25pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image017.png" o:title=""></imagedata></shape>

Here we can get the attribute and interface details of the BADI. As this one is screen BADI sub-screen tab also is there.

<shape id="_x0000_i1034" style="WIDTH: 302.25pt; HEIGHT: 224.25pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image019.png" o:title=""></imagedata></shape>

Step 4:

To implement the BADI, we have transaction SE19.

To create new BADI to implement the put your BADI name here. If the BADI is an enhancement-point then put the BADI name in option NEW BADI and if only BADI then put the name in CLASSIC BADI.

<shape id="_x0000_i1035" style="WIDTH: 325.5pt; HEIGHT: 214.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image021.png" o:title=""></imagedata></shape>

Give the BADI name and click on create button.

<shape id="_x0000_i1036" style="WIDTH: 269.25pt; HEIGHT: 213.75pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image023.png" o:title=""></imagedata></shape>

Press F8.

<shape id="_x0000_i1038" style="WIDTH: 290.25pt; HEIGHT: 205.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image025.png" o:title=""></imagedata></shape>

Again press F8. Give an implementation name. Let it be ZTTTTT

<shape id="_x0000_i1037" style="WIDTH: 6in; HEIGHT: 157.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image027.png" o:title=""></imagedata></shape>

Give the description and select a suitable method double click to get into the method to put the ABAP code.

To edit an implemented BADI the below portion is used. Click on the change button to edit the BADI.

<shape id="_x0000_i1026" style="WIDTH: 308.25pt; HEIGHT: 210.75pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image003.png" o:title=""></imagedata></shape>

EXAMPLE: To change the description of a material in transaction MM02.

Step 1:

Run the transaction SE24. Under object type put the class name ‘CL_EXITHANDLER’.

Click on display button.

<shape id="_x0000_i1027" style="WIDTH: 309.75pt; HEIGHT: 118.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image005.png" o:title=""></imagedata></shape>

Under this class ‘CL_EXITHANDLER’ select the method ‘GET_INSTANCE’ and double click.

<shape id="_x0000_i1028" style="WIDTH: 315pt; HEIGHT: 222pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image007.png" o:title=""></imagedata></shape>

Under the method ‘GET_INSTANCE’ put break point on a function module called

CALL METHOD CL_EXITHANDLER=>GET_CLASS_NAME_BY_INTERFACE’

<shape id="_x0000_i1029" style="WIDTH: 324.75pt; HEIGHT: 241.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image009.png" o:title=""></imagedata></shape>

Step 2:

Then according to the requirement run the transaction. In this example transaction code is MM02.

Run the transaction MM02. As in 1^st step we have putted a break point, that function module will give all BADI used by the transaction in each screen and activity on the application (MM02).

<shape id="_x0000_i1031" style="WIDTH: 303.75pt; HEIGHT: 251.25pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image013.png" o:title=""></imagedata></shape>

Press F8 to get the BADI used.

Step 3:

Run the transaction SE18 to see the details of BADI.

Choose the method where the material description is defined.

<shape id="_x0000_i1032" style="WIDTH: 393pt; HEIGHT: 106.5pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image013.png" o:title=""></imagedata></shape>

Step 4:

Run the transaction SE19 and create an implementation for the corresponding BADI. Click on create button to create an implementation.

<shape id="_x0000_i1031" style="WIDTH: 423pt; HEIGHT: 203.25pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image015.png" o:title="" cropbottom="18417f" cropright="24637f"></imagedata></shape>

Give a name for the implementation.

<shape id="_x0000_i1033" style="WIDTH: 6in; HEIGHT: 107.25pt" type="#_x0000_t75"><imagedata src="file:///C:/DOCUME~1/PARVAT~1/LOCALS~1/Temp/msoclip1/01/clip_image017.png" o:title=""></imagedata></shape>

Give the description. Click on save icon and double click on the method chosen.
