VAT File Update

[Mpeter]

Hello,

We have a requirement where in when I run the Sales Update , followed by the POST Program ( .. a standard process) and requested NOT to book any VAT entries!!

I know there is a processing option in P09800 which controls this. I have made it blank , but still I can see an entry in F0018?

Is this controlled some where else like the ( Customer + Item Level) apart from the PO of P09800???

Please let me know?

Thanks
Mark
