Issue with Postings-Profit center

Hello,

We have a issue with Spec. Purpose Ledger account.

There are 5 items in that account with 5 g/l accounts are updating. Out of 5, in 2 accounts profit center is updating wrongly.

When we check that one of them is updating tax value. The profit center is updating from defaulted profit center assigned to company code and that specific G/L account. This is because when the value of the profit center is blank from where it has to pick the profit center, then default profit center should come. So this case is happening.

Now I would like to know for tax values, from where the profit center will be picking.

Please reply if this information is not sufficient.

Best regards,

SASi
