How to Set up Self Billing( Pay on Receipt autoinvoice) to match Tax lines to the PO in Payables wor

 Currently, when we run the ER(Evaluated Receipt Settlement) job, it created tax correctly in payables.

The problem is that the Tax lines created via the ERS job are not match to the Purchase order that was used as the base to create the self billing. Today, the item lines are matched to the PO and not the tax lines in the Line tab of the Payables workbench and this creates TAX ACCRUALS in the AP and PO Accrual reconciliation report that will not drop-off the report.- the tax accrual is a result of matching the AP amount(excluding tax) against the PO amount( that includes tax), this creates a difference of the tax amount on AP side.
