We are settling the cost of WBS to AUC. For this we have created AUC.
While settlement we are getting below error.
Transaction in area 30 contradicts the net book value rule
Message no. AA660
The document cannot be posted, as it is contrary to the net book value rule which is checked in area 30.
This error usually occurs when you enter proportional values. The proportional values exceed the amount posted, for example, post capitalization of 100 but proportional depreciation to the amount 110. Check your entries and correct them if necessary.
We have created some 26 AUC and where working fine. Now for 27 th one we are getting above error.
Please kindly help
There are 2 options to have the issue resolved :
1>Activate the indicator "negative values allowed" - "XNEGA", with this indicator you can avoid AA660.
For this, use transaction AS02 and activate the field 'Negative values allowed' for the asset as per note 141656.
Pleaes read this note carefully.
2>In OADB you go to Net Book Value and have "all values allowed"
Also make sure that the below notes are in your system:
SAP Note No. 1160532
SAP Note No. 1231973
For AuC it is generally necessary to allow all values in OADB, this is documented in several SAP notes that is it important that for
AuC's negative values are allowed.
A lot of the time there is so much movement on an asset like the AuC and involves postings over several fiscal years, that the system often gets into a "negative value" situation at certain point of additinal postings, such as credits for previous year. Since it the system clearly distinguishes between current and previous fiscal years in regards to transaction types for example it can happen very easily that a posting becomes, even if only 'temporarely', negative.
Since Asset under Constructions do not post depreciation, a change to allow negative values, will not create negative impacts on the asset values otherwise nor should it get in conflict with legal requirements.
I suggest you also to read note note 1025126 about the matter.
I believe this helps.
