From the above screen, we can understand how system migrates the balance into ACDOCA. System will update the balance of Asset with reference to Asset number and with the document number “DA”
System will migrate the FI-GL balance without reference to Asset with the document number “DG”;
System will migrate the Delta without reference to Asset with the document number ” DU” where U- Total Correction for G/L
The field Migration Source plays a very important role in identify source of the data.
By this , after S/4 conversion when we execute any same asset report in source ECC and Target S/4 both the report will match perfectly. As in S/4 Only the document DA will be pulled for Asset report.
Later, when you execute any of the G/L balance report in both ECC and target S/4. The balance of G/L will match correctly. As the system will compute the balance using the value of DG documents.
The Delta DU- will remain in ACDOCA forever. This Delta can never be reconciled in S/4 Hana post conversion .
Hence as a finance consultant one should understand the importance of ABST and ABST2 before S/4 conversion and decide wisely on how to handle the delta.
