Dear all.
Problem was solved!
The error was in the withholding tax accounts. The commitment item assigned to these accounts had the financial transaction set to 40 and was not flagged as stat.
I made the changes suggested by the thread below in the commitment itme assigned to these accounts and now everything is working properly.
withholding taxes at invoice are not totally updated at FMF0
Thanks to everyone for your help!.
Mauro.
