Diagnosis
You have maintained a reference assignment.
By carrying out this assignment, thestore concerned receivesthe assortment for thereference store. All the materials for the reference store would nowhave to be sent to the store concerned in the change download. As weare talking about the entire assortment of the reference store, thatis, mass data, and since sending the entire assortment of a store isthe same in terms of volume of data as initializing the store, it isbetter for performance to initialize the store. If you reopen a storeand copy the assortment by assigning a reference store, you also needto execute the initialization applications (WPMI or WDBI) for the storein order to implement engineering change management in the following.

System Response
Engineeering change management in the applications POS outbound (WPMU)and assortment list (WDBU) does not react automatically to theassignment of reference stores.

Procedure
If you use the applications POS outbound or assortment list, you mustinitialize them using transactions WPMI and WDBI respectively. Thestores then receive the changes due to the reference assignmentrelevant to them in engineering change management.
