Need Some Help On SAP to JDE Mapping

Interesting one that I've not handled before of SAP data needing back into JDE.

So one group already on SAP, with now data within MM module, and inventory needs to transfer into another one that is JDE-based, namely item master table and

then likely onto Branch Plant.

However appears some concerns for existing fields would need to go into some specific fields that have default values that don't seem to match up.

An example: Order Policy Code, IMOPC, doesn't really align to the plan of already defined SAP Order codes or the SAP field to be defined

elsewhere in the table? So not sure how to get those in as desired or is one forced to update the associated UDC against that to match then
