Hi Shailendra,

I currently do have access to the SAP system. I had a similar issue like this and it was solved with the solution i suggested.

Please refer to SAP Note 0000019048 - AA617 with credit memo on fixed asset / AuC settlement, extract is below:-



With a fixed asset or asset under construction (AuC), the system can issue the error message AA617 #In the area xx, the acquisition value is negative# in the following cases:

1. if a credit memo should be posted to a fixed asset before an acquisition is posted.

2. if the credit memo is higher than the existing acquisition value of the fixed asset.

3. if acquisitions are posted before credit memos in the settlement of AuCs.

Reason and Prerequisites

In one or several depreciation areas, negative acquisition values are not allowed on fixed assets. There can actually only be negative values when an asset under construction (AuC) has already been settled and there are still subsequent credit memos to post.

In the settlement of an AuC, the acquisitions and credit memos are summarized in each case and posted to the receiver one after the other. If the acquisitions were posted first and the credit memos second, then in the settlement, after the acquisitions are transferred, only the negative credit memos remain on the asset.


The AuC has the following postings:

Asset value date Value Transaction type

Feb 1, 2003 1.000.00 Acquisition

Feb 2, 2003 100.00 Acquisition

Feb 3, 2003 -100.00 Credit memo

Feb 4, 2003 -100.00 Credit memo

Accordingly, for February 4, 2003, the AuC has a net book value of 900,00. In the settlement to the receiver(s) on February 5, 2003, the following postings are made on the AuC:

Feb 5, 2003 -1.100.00 Summary of acquisitions

Feb 5, 2003 200.00 Summary of credit memos

However, after the first posting the net book value is 900.00 + -1.100.00 = -200.00. As a result, the system generates error message AA617 if no negative values are allowed on the AuC.


Generally, negative values should always be allowed for assets under construction. You should therefore make this setting at asset class level (Transaction OAYZ).

In the asset class of the AuCs in all depreciation areas, set the 'Negative values allowed' indicator (ANLB-XNEGA). Note that this change only takes effect for fixed assets that are created after the indicator is set. For existing fixed assets, set this indicator in the detail screen of the depreciation areas in the asset master (Transaction AS02). You may have to adjust the screen layout rule to do so.

Make this setting in AS02 for relevant individual assets.

Before you set the 'Negative values allowed' indicator, consider the related Note 141656.
