3079780 - MAA invoice amounts do not match expected values - SAP ERP & SAP S/4HANA

When creating an Invoice on the online transactions (MIRO/MIR7) and referencing it to a Purchase Order with Multiple Account Assignment (MAA), it is noticed that the amounts coming up for the different accounting lines do not match the remaining amounts to be invoiced.

For example, we have the following 4 accounts set for PO X with some value invoiced already:

Acc. Assig. counter (ZEKKN)	Percentage	Total Value	Sum Invoiced so far	Sum remaining to be invoiced
1	10	200	150	50
2	20	400	300	100
3	30	600	300	300
4	40	800	500	300

Regardless, the values coming up in MIRO (under the MAA button) when trying to create the invoice are different from the remaining ones.

One example could be the following:

Acc. Assig. counter (ZEKKN)	Value
1
2	100
3	300
4	125

Prerequisites:

• PO has Multiple Account Assignment
• Distribution is done by percentage and proportionally (in case of partial invoice)
• PO item refers to services and no GR is expected
