iVend 6.5 update 6
Stock transfer request only created between warhouses which mapped to stores(Retail) and not General Warhouse.
Proposed Solution:
NA
In SAP R3 , value needs to be passed from middleware to make it a general warehouse. In SAP we have Store and Warehouse and no concept of General or Retail. in SAP we create a warehouse and site (store), Site is pushed as warehouse type (Retail) and Warehouse is pushed as (General).This mapping is done in PI/PO.

General/Retail / INTRANSIT warehouse is a concept in iVend which is determined by value 0/1/2 (General = 0, Retail = 1, InTransit = 2)
Request to please check what values (store type General = 0, Retail = 1, InTransit = 2 ) are passing from middleware to ivend HO.
