Error: Each line must have a unique combination of INTERFACE_LINE_CONTEXT and INTERFACE_LINE_ATTRIBUTE values for the transaction flexfield.

InterfaceLineAttribute1 and InterfaceLineAttribute2 are the same values across all 6 lines and InterfaceLineContext is the same for each transaction, i.e. 3 lines have the same value then the next three lines have a different value but same across those 3 lines. Oracle has separate transaction numbers for the two invoices (i.e. lines 1 to 3 have the same transaction #, lines 4 to 6 have the same transaction number but different than lines 1 to 3). But, within each Oracle transaction #, InterfaceLineAttribute3 is unique on each line.
