There are 750 subcontracting POs created by users in system, at two different locations - head office & regional office. The process is same for all users i.e. PO (ME21N)>>Issue to SC Vendor>>GR (MIGO) >>IR (MIRO). All invoices have been paid to subcontractor but the problem is that the regional team, instead of posting invoices through MIRO, have been paying them through FB60! Now, there are almost 400 POs in system that are left without IR since their payment was done without reference to any PO. This has happened over the last ten months, so reversals are not an option.
First choice - MR11 but there is hardly any stock coverage and account maintenance will hit price difference account, which is not acceptable.
Dear experts, what other choices are there to sort this out?
