Hi team,

As per Standard process, We have created Created PO in Business unit A and project and task info used from Busniess Unit B and AP invoice created with the same details ,validated and accounted.

Now when trying to Import the Supplier cost in project costing , I'm not able to import the PO matched supplier invoice costs in ppm .where as i have created manual invoice i.e. no PO invoice with same POET details which i m able to Import supplier costs.
