当然Help文档也是不能错过的http://help.sap.com/saphelp_47x200/helpdata/en/dc/6b828943d711d1893e0000e8323c4f/frameset.htm , 在help里除了IDoc extension, IDoc development以外, 用workflow来做exception handling讲得也不错.

 

IDoc Outbound/Inbound Debug

1. outbound (example of invoice):
    a) Set break point at your code
    b) Use T-code: VF02 and input invoice number.
    c) F8 then menu path: GOTO->HEADER->OUTPUT
    d) Give the output type and print medium should be 6(EDI) or A( ALE)
    e) Click on Further data and select->select send with periodically scheduled job and save it.
    f) SE38 and use RSNAST00, eg. data:
        Output Application : V3
        Object key - Invoice Number ( 10 digit)
        Output type - RD00( SAP Standard)
