Difference line and distribution in calculating tax on AP invoices

Hi,

We are processing a credit memo with several price corrections. When we calculate tax, there is a difference between the distribution tax and the calculated tax on the lines. The difference is caused by how Oracle calculate tax. The distribution tax lines are calculated by line and the tax of the invoice lines are calculated by the total amount. The distribution tax lines are round off, so that's caused a difference of 0,01.

This happens only in case of price corrections. How can we deal with this?

I hope someone has some ideas.

Thank you,

Patricia
