Can anyone help me to understand the Groff lot size heuristic in SAP APOPP/DS (SAP_PP_013)?

As far as I know the data from the product master „Procurement costs“ and „Stock costs“ are relevant for the calculation. Unfortunately I am not able to understand the way SAP APO calculates the lot sizes with the SAP_PP_013 procedure.

Is there any documentation available about the calculation in detail? Any online tool to see the calculation?

Thanks for your help and recommendations.

Best regards,

Jan Schmitz

Hi Jan,

I don't have experience with SAP_PP_013, so I cannot provide a detailed answer myself, but I looked for what documentation is available on it anyway, hope this helps.

Note "538201 - Groff reorder procedure/part period balancing" provides some calculation examples.

In SE37, you can display Function Module /SAPAPO/HEU_PART_PERIOD and click Function Module Documentation button. This provides some detailed information on SAP_PP_013's behavior.

Additionally, SAP Help for Lot-Sizing Procedure has in section Other Lot-Sizing Procedures some other information which may help.

Hi Tiago,

thank you very much for your help!

Note 538201 looks good to me. It provides some new information that I did not find at any other place.
