BW report by Material group

Question

Hello BW Gurus,
I have a Quarterly report in BW, which i have to review each line and combine the sales for the same product .  The initial report has 4000 products on the report.  After I combine the products, there are 2238.  I would like a way to streamline this process.
There are list of product that should be grouped as 1 for the purpose of this report. For Example see below
Material group   Group Name     Material                           Description
1          Audio                            6003707                           AMS KIT-
1          Audio                            6500786                           AMS KIT-
1          Audio                            6500284                           AMS W/O KIT
1          Audio                            6003437                           AMS W/O KIT-
Is there are any ways other can creating a hierarchy in BW? I know even if we create a hierarchy based on these material the users has to notify me when items are updated in the material master that affects the groupings..
Is there a solution for this?
Appreciate your time and response guys..
Regards Renny

Answer 1

Is there a reason you cannot create a navigational attribute for the product group, and use that instead of the material ? We do that in our company. In fact most aggregate material focused reporting uses it, so we've actually added it directly to our data models to avoid navigational attribute performance issues.
