R12.1.3 AP Payment Priority data not transferred through Paybles Invoice Import program

 Dear All,We have supplier Invoice creation requirement from external system. Here is the business scenario,

External system data pushing into oracle ERP staging table along with Payment Priority information. I have transferred the data from staging table to Interface table  & Base tables successfully. But payment priority data is not reflecting in Payment schedule tab in Invoice form.(

I think System is picking payment priority data from Supplier master.

Kindly suggest me How to transfer payment priority data through Payables invoice import program.
