FI-AA: Asset below-zero value

[myRG]

Dear Guru,

there is one asset which contain amount which marked as Below-zero value as in snapshot:

i am trying to run depreciation in tcode: AFAB gets error message:

Error when creating line items using line item schema SAP_500_724...

Message No. AA548

Diagnosis

The system found inconsistencies in the structure of the FI document line items. Line item schema SAP_500_724 does not provide reliable results in relation to posting to the general ledger.

Procedure

Check line item schema SAP_500_724 for this posting transaction. There are two possible causes for the error:
1. A value field was updated on the asset, and this value field is updated to a reconciliation account in FI (for example, an asset balance sheet account, accumulated depreciation or down payments), but there is no line item defined for this value field in the line item schema.
2. The error message can also be caused by incorrect account allocation. In order to find out if you have incorrect account allocations in the account determination for Asset Accounting, carry out a consistency check of the accounts. The consistency check is part of FI-AA Customizing.

i couldn't why it does happen, please help.

thanks,

RTN

Hello dear user,

And thank you for asking your question in the SAP Community blog.

You're getting the error AA548 when trying to run depreciation in AFAB. That usually means SAP is trying to post accounting entries for depreciation but something is missing or misconfigured in the background specifically, in the setup of how asset accounting connects to the general ledger.

The message says there's a problem with the line item schema SAP_500_724. That schema controls what accounting entries are created during depreciation. If something is missing, like a GL account, the system can't generate the journal entries and throws this error.

Here's what you can check:

1. Account Determination (AO90)
Go to transaction AO90 and check if the right GL accounts are assigned for your asset class and depreciation areas. Make sure there are accounts for:

• Asset acquisition
• Depreciation expense
• Accumulated depreciation

2. Asset Master Data (AS03)
Look at the asset you're depreciating. Make sure:

• It has the right asset class
• The depreciation area is active and correctly set up
• It uses a valid depreciation key

3. Run AFAB in test mode
Try running the depreciation with test run + detailed log. SAP will usually show you which asset or account is causing the problem.

4. S/4HANA-specific
If you're on S/4HANA, make sure your depreciation expense accounts are also set up as secondary cost elements, since they now post to both FI and CO.

I hope this will help you answer your question.

Best regards,

Jeremy
