Help on OIB_QCI_ROUND BADI

Hi,

I had implemented the badi OIB_QCI_ROUND (IF_EX_OIB_QCI_ROUND_QTY~ROUND_QTY) and it works fine when I use BDC for PGI. This BADI is called for each line item of delivery.

But When I use the BAPI or FM then the badi is called but the data of item,uom are blank while import as the export statement written in other BADI is not getting called.

Can any one please do share any suggestions on this. The FM used is WS_DELIVERY_UPDATE.
