Background Processing: Message Bundling 
Use
Program RWNASTVP generates group NAST records from the individual NAST records created using output determination. This sorts article-related data at site level.
When creating a promotion, start program RWNASTVP.
The group NAST records generated in this way are processed by the output processing program RSNAST00. A paper printout is then made.
Prerequisites
You should run program RWNASTVP immediately before program RSNAST00.
Activities
We recommend you run the program daily.
