APO DP: Disaggregation to product&plant level from higher levels.

Question

Hi.
We do demand planning on groups of products and for country/region in general, we have around 48.000 CVC's in our current setup. It works very well.
A new situation has arisen where we need to have the forecast split down to product and plant level.
As is we simply don't have the information at this level of granularity.
I don't see how we can add for instance product to our setup, we have around 20.000 products so the number of CVC's in DP would become massive if we did this.
I was thinking that perhaps something could be done by exporting the relevant key figures to a new DP setup with fewer characteristics (to keep the number of CVC's down) via some infocubes, perhaps some disaggregation could be done via some tables and the BW update rules. This still leaves the issue of how to get the figures properly disaggregated to plant and product though.
Does anyone have experiences on how to get the figures split to lower levels from DP when you're planning on a higher level?

Answer 1

Simon,
One approach as you mentioned can be creating Z Table where in you set up disaggregation proportion from product group level to product level or product location level.
Product Group X  100       Product A@loc1 10
                                      Product B@loc1 90
Download your planning area data into infocube C and then use BW routines to convert the data from group in infocube C to lower level refereing Z Table....into another infocube..
SAP also provides such standard functionality of spliting the aggregate Demand plan to detailed level
SNP plan..through functionality like location slit or product split.
Essential you will be using same concept in yor BW solution or you may also want to consider the
release your DP to SNP planning area its as solution of diaggregation of data  to lower level.
