For audit purpose, we would like to block invoices for payment when they're posted through MIRO with some direct posting on GL (GL tab in MIRO lines).
Basically, when user is assigning some unexpected cost to a certain GL/Cost center or Internal order.
I know it is possible to unactivate completely the tab in the Customizing (Materials Management -> Logistic Invoice verification -> Incoming Invoice -> Activate direct postings to G/L accounts and material accounts)
(We also use the Unplanned cost field, but there's only one field and it will all post in one GL only or split among GR lines.)
But I need to let the GL tab available and useable to users in MIRO, as they have to allocate these amounts on specific GL, depending on the type of the charges. I just need the invoice to be blocked for payment and to require additional step of unblocking (unblock in MRBR for example). Is that feasible ? If yes, can we control that by setting a limit above which the block would happen ?
The audit issue here, is that part of the invoice amount is directly allocated somewhere without any additional control.
Thanks for your help !
