In the option to post a reversal (FB08), the system uses the same dollar, strong currency, value as originally published. Correct, when we talk about incorrect postings or posting to non-monetary accounts.
However, when you use the accounting system where you reverse a provision in full, to post the new value instead of making a supplementary entry. This leaves an impact on the exchange rate variation.
I need a new form of reversal, in which the dollar amount is translated on the day the reversal is recorded, rather than the original entry.
