R12 payment document do not differentiate between different operating units
We are R12 (12.0.4)
We have two legal entities, two ledgers with the same chart and two different operating units. We defined different banks and assigned each one to its related operating unit.
Our problem while making an electronic payment in one of the AP operating units it picks up the serial of the other payment document in the other bank related to the other operating unit.
We defined the payment document and it should start from one. When we create the payment we see number one as the document number but once we save this document number gone and picks the other payment document number that relates to another bank and operating unit.
