Importance of Report ABST & ABST2 in Asset Accounting before S/4 Conversion

Hi Everyone, This article is a continuation to my earlier article on S/4 conversion checklist. I would like to cover the importance of reconciling Asset Accounting sub-ledger with General Ledger before conversion.

1. I would like to make a clear note that system will not stop you from converting to S/4 Hana if you have value mismatch between FI-AA and FI-GL.
2. As part of Pre-Conversion ABST (RAABST01) and ABST2 (RAABST02) are recommended Pre-conversion consistency check report that should be performed by the Finance consultant before conversion. This report should be executed and analyse if there is any mismatch between FI-AA and FI-GL. Then that should be reconciled in your source ECC system.
3. ABST and ABST2 are obsolete in S/4. And you do not have the option to reconcile in S/4. If you migrate with a difference. Then Customers has to live with the difference going forward. This can never be reconciled at any point later in S/4.
4. Let us take an simple example to explain how this balance is migrated to S/4.

FI- AA value = 1000 $ and the FI-GL Recon balance = 970$ ; We could see the delta of 30. When you execute ABST and ABST2 we can narrow down which particular G/L account has this discrepancies. This report will also fetch the difference in parallel ledger and parallel currencies as well .

Now the Billion Dollar question comes into mind? What balance will S/4 take into consideration during S/4 migration will it take 1000$ and update the same 1000$ in G/L or since you financials are already audited and reported with 970$ . Hence S/4 will migrated 970$ in both Asset and G/L. ( Remember Single Source of Truth )

To Answer this question, I would like to explain with the below case
