Hi, need to know how to have different BU to be populated for RNV account

Hi,

Business Scenario- Different Cost Centers are involved in Purchase of same item. hence need to have different BU.Object.Sub (only different BU will also be helpful)  to be populated on every Purchase order detail line so that RNV (4320) will be recorded in different accounts.

We can use J line type and achieve this, but user would like have the account number to be defaulted automatically.

How should i use Flex accounting in this scenario?

Thanks in advance

BR,
