Withholding tax certificate numbers - how to reset ?

Hi Gurus,

I have an issue with witholding tax certifcates numbers for Venezuela and their VAT reporting. User have run report S_P00_07000134 - Generic Withholding Tax Reporting twice in "update" mode which updated certificate numbers in table WITH_ITEM for FI documents. Now they want to revert back to the first range of numbers (from first run).

I identified the number ranges for these certificate numbers in table NRIV and was able to adjust their statuses for previous values but i didn't help at all. The report is not updating numbers accroding to current ststuses of these ranges.

Is there any way to reset these numbers ?

thanks a lot

with regards

Michal
