Intercompany : Inter Plant stock transfer

Dear SAP Guru's,

We have done the configs of Intercompany stock transfer.

And Set the Purchase order for stock transfer in the CUstomization of MM.

(Keeping in mind two comany codes two plants all configs)

Then we have created PO document type NB and the delivery type NLCC ..

When we create outbound delivery through VL10b the purchase order is put in the Column.

The activities due for shipping there the purchase order is not appearing

What could be done from the SD side..

regards,

Amlan Sarkar
