Background Processing: Automatically Generating Assortment Lists 
Use
If you use the automatic option, you can have the system generate either a full version or a change version assortment list in cycles.
Prerequisites
Before change versions and full versions of the assortment list can be generated in cycles, a site has to be initialized.
The relevant programs for background processing are:
-
RWDBBINI for initializing a siteProgram RWDBBINI is used for the initial transport of the assortment list/shelf-edge labeling data to stores with the appropriate sales organization, distribution chain and site, using selectable assortment list categories.

The program is only run when this data is transported to the stores for the first time.
If the data is transported again, you use program RWDBBUPD.
Program RWDBBUPD sends the relevant data to the stores.

Assortment program RWSORT07 must run beforehand.
It is not necessary to run the program daily. We recommend that you run the program weekly, at the weekend.
Activities
In the Control check box, you can select parallel processing. This is recommended if a large number of recipients (for example, stores) receive assortment lists. You can enter the maximum number of parallel processes and a server group to be used.
Generate mixed versions means that you combine the last assortment list with assortment list changes. SAP recommends you generate mixed versions to improve performance.

The cycle and the number of change versions which have to be created before a full version is created, is defined in the assortment list type.
