Assignmnt num population(BSEG-ZUONR) in all line of Acc doc for Cr Memo(G2)

Question

Hi,
Our business process is we create Credit memo request with reference to Returns Sales order and create Credit memo with reference to Credit memo request.
When creating Accounting document from Invoice Assignment number(VBRK-ZUONR) is copied to BSEG-ZUONR of customer line item as well as GL Account line items in the Accounting document.
When creating Acc Doc from Credit memo Assignment number(VBRK-ZUONR) is copied to BSEG-ZUONR of Customer line item only but not GL Account line items in the Accounting document.
The same Customer & GL Account is used in both cases.
Please hlep us to resolve the issue.
Thanks in advance.
Regards,
Rahul

Dear Rahul,
I think It's SAP standard behaviour that field BSEG-ZUONR is not filled in     
accounting item lines when you transfer a billing document to          
accounting. Please have a look at program LV60BF00,                    
form accounting_item:                                                  
Felder, die nur in den Steuerzeilen vorkommen                        
  clear xaccit-kbetr.                                                  
  if vbrk-vbtyp ca vbtyp_reli.                              "WIA       
    clear xaccit-stceg.                                                
  endif.                                                    "WIA       
  clear xaccit-vbeln.                                                  
  clear xaccit-xblnr.                                                  
  clear xaccit-zuonr.                               ' <    here !!!    
  clear xaccit-gjahr.                                                  
If you want to have this field filled for all item lines in accounting,
then you have to use userexits to fill XACCIT-ZUONR. E.g. you can use  
FUNCTION EXIT_SAPLV60B_004 to set XACCIT-ZUONR = VBRK-ZUONR in the     
line items.                                                            
I hope this helps.
