PPM in CTM: Activity Relationships

Dear Friends,

Here a query from my side:

As per CTM Faq note: 855229, CTM supports only End-Start Relationship activities.

We are generating PPMs without Lot Size Margin in APO 4.1 and are getting start-start relationships. This is inspite of the fact, that in the PPDS PPM, the activity relationships are end-start.

Could anyone throw some light on why this is happening? Any note for further reference would be really helpful

Looking forward to hear,

Sudhir

    Hi Sudhir

    CTM is a SNP functionality , so in SNP parellel relationship is not supported in application area>PPM and as well in PDS.

    Since SNP /CTM PPM is using the PPDS PPM to generate you will face problem in application area too.

    Now you need to use PDS inspite of PPM(Since for PPM SAP stopped the development work).

    For PDS - You have an option of generation CTM PDS while generating a PPDS PPM ,there is a Badi needs to be activated for this.

    Start-starts will not be supported.,since this creates a parellel sequece!

    But you want start-start ,in the CTM you can use PPDS source of supply,but the order will be a PPDS Source order,if you dont want then follow the other options.

    I hope I have clarified your doubt.

    Kind regards,

    sundar

      Hello Sudhir,

      I think the problem in your case, having start-start relationship may be due to the usage of overlapping in the routing in R/3.

      I know this from PDS. but, I am not very sure in PPM.

      It is better to find notes on overlapping in PPM.

      Or, the PP/DS PPM could have been changed manually to get this relationship.

      hence, it is better to transfer a new PP/DS PPM and check wheher start-start relationships were created. if not, there should be some issue in the conversion into SNP/CTM.

      Even in PDS, usage of overlapping will lead to start-start, end-end relationships.

      Regards,
