FF702 - Iteration not convergent: tax code & net & &

SAP Error Message - Details

• Message type: E = Error

• Message class: FF - FI Function Module Messages

• Message number: 702

• Message text: Iteration not convergent: tax code & net & &

What causes this issue?

You are posting to a company code in which the tax of the net goods
value (reduced by a possible cash discount) and the cash discount of
the net invoice value (gross value reduced by the tax) is to be
calculated. You set the parameters in the company code table.
In the case of the posting entered, you want to calculate the tax from
the gross value and also have the system determine the cash discount
base value. The system now attempts to determine both values, however,
does not have sufficient convergence of the results after a certain
number of arithmetic operations. You can find the last two tax amounts
determined in the status bar.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Enter the tax amount specifically or enter the amount eligible for cash
discount in the open item account line items.
