Default Warehouse for Mass Receipt

I am having an issue when receiving a purchase order that is purchased to other. Prior to our update to this version, it would automatically default to our main warehouse. On this version (9.05.702), it shows up blank for this type of receipt. Epicor knows that this is a bug but doesn't have a fix date for it yet. Does anyone know how to write a BPM that would populate the field when it is blank?


Thanks
