What are the difference between the production process

model (PPM) and the production data structure (PDS).....?

are they totally similar or there are specific applications in which either one of them is only usefull.....?

Thanks in advance.

Hi ,

The PPM is the master data which was available from the very beginning

of APO but will not be developed any further due to some structural limitations

(mainly the lack of engineering change management). The alternative

to the PPM is the PDS. The functionality of the PDS was increased for

APO 4.1. In the releases APO 3.1 and 4.0 the PDS was called run-time object

(RTO). The SAP recommendation is to use PDS for new implementations

whenever possible.

Also check below link

also refer SAP note 1079959 to get the full detailed information on differences between PPM & PDS.

Hope it helps you.

Hi Adding to all above answers, we need to talk about two more points specifically

1. PPM is editable in APO where PDS is only display mode.

2. As you change BOM/Routing/Prod version in R/3 PDS will be updated by the integration model as it is done. but we have the limitation for PPM. With the integration models system will generate PPDS PPM and we manually generate SNP PPM. so once the chagnes done in R/3 will not chagne the SNP PPM. this is the only biggest limitation of PPM.
