Hi,
My question was whether you follow your budget up to payment itself, i.e. is it important for you to know budgetary-wise if the invoice was paid. In FM these values will be registered with '57' value type. If the answer is positive, then you cannot base your FM update only on GR: it has to be IR or IR/GR. Otherwise, you can base your FM update on GR.
Your second point is not clear: what do you mean by making 'payment to commitment budget'?
Regards,
Eli
