DFF segment values of imported receivables invoices

Hello,

I have the following two questions:

1. Please let me know if it feasible to store two different values in the segments of the following two descriptive flexfields for a receivables invoice imported from an external source:

a) Line Transaction Flexfield where Interface Line Attribute1 is Segment 1

b) Invoice Transaction Flexfield where Interface Header Attribute1 is Segment 1

2. If yes, please let me how the two different values should be populated in the following two interface tables:

a) ra_interface_lines_all

b) ra_interface_distributions_all

P.S. Oracle EBS version is 12.2.8.

Thanks & Regards
