GL to PC Allocation is failing on Transaction Line No join

We are trying to create a PeopleSoft Allocation to pull in fringe benefits from the General Ledger tables into the INTFC_PROJ_RES table.  In the Target, we defined the the Transaction ID = Seq No. along with the projectID, date = req date, and other fields.  We selected no offset.  In the batch records, we used delivered GL TOA tables for the pool & basis, but PC TAO tables for the target.  When we run teh allocation, we get an error:
