Net requirement calculation tolerances in MTS

Former Member

Colleagues,

We are trying to find a method to fix an issue that we have around tolerances when running CTP heuristics.

Let me start by stating that:

  • We are in mills ECC 6.0
  • We the switch DIMP activated
  • We are running also APO
  • Our scenario is very mill specific and we are running MTS configurable.

In a very simple explanation we are creating sales orders with a series of characteristics like:

  • Grade
  • Width
  • Diameter
  • Core code
  • Sales order number
  • Sales order item

As you can see we added sales order number and item as characteristics which makes the planning segement very unique without having the contraints of MTO.

Our issue is once our sales order is saved and APO planned order gets created immediately (that's working fine).

The planned order and transferred to a TRIM optimizer via a certified SAP APO interface and we get back from the optimizer a new type of planned order called a TRIM sheet order (which is in fact a multiple output). Again this is also working fine.

Now the quantity that we get back from the optimizer always varries from the initial quantity (1 or 2%). A higher quantity is never an issue but if the returned quantity is less than the initial quantity we get a RESIDUAL planned order created for a very small quantity that we will never ever produce.

This is polluting our planning results with a very large number of these small residuals.

SAP has a standard fix for this for MTO only but we must find a solution for MTS.

Is there an enhancement in APO that would allow us to influence the "Net requirements calculation" in order to consider a percentage %. This value could be ideally maintained:

  • At a sales order level with under delivery tolerances
  • At a characteristics level which would be CIFed to APO
  • Or at a product level (a flat % value)

Thanks for your help in advance

Hi Eric,

Have you already tried using the Overall Delivery Tolerance (Under / Over) and Individual Product Tolerance (Minus / Plus) fields available on Pegging sub-screen of Demand tab on the product master? Additionally, you mentioned that you use TRIM optimizer. Is this part of SAP APO or a non-SAP optimizer solution?

Thank you,

Regards,

Jagjeet.
