How to create a transfer order for stock lying in consignment?

Hi All,

I'm stuck creation of Transfer Order. The scenario is for Intercompany Stock Transfer.

The delivering plant has the requested material as consignment stock only (in a bin in storage type HRC). When the delivering plant attempts to create TO for Outbound Delivery, the error says "System can not find storage bin". When I enter the source storage type and bin, the system says 'Storage type HRC doesn't allow negative stock figure".

My question is, how to enable the system to search the consignment stock?

Thanks,

Rana
