aggregation mode along one dimension (product) different than along the time dimension

Dear All,

In IBP S&OP, Is it possible that the aggregation mode along one dimension (product) could be different than along the time dimension?

For a demo, a customer has an input at the product family level (vehicle production) which we just “copy” for disaggregation purposes, to the product level (parts), see attached. So for aggregation we used average.

However, time-wise, we need to sum it up.

Thanks for your insight and help.

Kind Regards,

Hi Omar,

Yes it is possible.

1. Create a new planning level (say PERPRODCUST1) which will be a copy of PERPRODCUST (you base planning level).

2. In the PER section of PERPRODCUST1, do NOT mark any period attribute as root. In other words, the roots for this PL will only be PRDID and CUSTID.

3. Now your KF calculations will be:



Since your KF is editable, it is worth mentioning that, following the above steps has trade-offs. Since your KF is editable, you will have issues with disaggregation when you enter the values at an aggregated level of both time and other attributes. My recommendation (for your configuration) is that this will work fine as long you enter the values at the root level of you time attribute.

Hope this helps,
