problem CTM calculation in case of IC groups

Hello all,

We have some problems with the calculation of production plan with CTM for interchangeable products.


Model A will be replaced by model B on 01/12/2014. Model A has a demand of 200 pcs safter 01/12/2014 and a stock of 500 pcs at the end of the horizon. Model B has a demand of 2000 pcs from 01/12/2014 onwards.

We created an IC group for both products with following characteristics:

     Valid date = 01/12/2014

     Location = Cross-location

     Direction = Full

     Use up strategy = Yes

After we run CTM, we see that 2200 planned orders are created for model B.

The 500 pcs of model A, which are still in stock at the end of the horizon,are not taking into account.

From my point of view, if direction is set on full, also supplies of model A should still be taken into account and only 1700 planned orders should be created for model B.

Kind regards,
