settlement Auc question

Dear Sirs/ Madams

When I execute the T-code (AIBU) to do settlement Auc, the result shows that the settlement amount is error.

The condition is following,

1. The Auc amount is recorded from multiple purchase orders.

2. In order to do T-code AIAB to maintain settlement rule. We filled fixed amount to u201Cequivalence no. fieldu201D for multiple fixed asset numbers.

3. After executing T-code AIBU testing run, we found that the each amount of fixed assets and the total amount of fixed assets appear difference. Although, the total amount is right, the amount of each item is error.

I think that the above problem is from SAP itself. We expect to know how to solve this problem.

Looking forward to hearing from you.

Best Regards.

Jacky.
