Dear Suresh,

please find below the detailed comparative account of PDS Vs PPM. You can copy and put it in an excel sheet in different columns and then read which is easy to understand.

PDS:

1. Production Data Structure (PDS) in APO 3.1 & Run Time Object (RTO) in 4.0 and above versions

2. Master Data Object

3. Useful for scenarios where the compoenent has got different validity periods

4. Used as Master data Basis for Planning in SAP-APO

5. Contains active Master data from iPPE (Integrated Product and Process Engineering) generated from a production version

6. PPDS PDS & SNP PDS can be used as master data for planning

7. Change Management, variant configuration & Phantom assemplies are supported in PDS

8. Sub-contracting in SNP is fully integrated with R/3 is supported in PDS

9. Direct transfer of SNP PDS from R/3 is possible

10.Rapid Planning Matrix can be generated

11. Not possible to maintain PDS directly in APO and can be used only in combination with R/3

12. The transfer of data changes is simpler

13. Not possible to create alternate SNP-PDS in std system for different mode combinations

14. PDS can be automatically generated from two sources ie R/3 and iPPE

PPM:

1. Production Process Model

2. Master Data Object

3. Cannot be used for scenarios where the component has got different validity period

4. Used as Master data Basis for Planning in SAP-APO

5. Contains active Master data generated from the combination of routing (BoM & receipe) and production versions

6. PPDS PPM & SNP PPM's can be used as master data for planning

7. Not supported by PPM

8. Not supported by PPM

9. Not possible here. SNP PPMs will be generated via PPDS PPMs

10. Not possible

11. PPMs can be directly created in APO and can be modified without R/3 also.

12. Little Complex when compared to PDS

13. Alternate SNP-PPMs can be easily created

14. PPM can be generated automatically generated only from R/3

Thanks for details difference between PDS and PPM

Point no.13 under PDS ,

PDS

Alternative modes for the PDS can either be created using alternative sequences or resource classification but not both. (Ref- PDS-Guide for the Implementation of and Upgrade to SCM 4.1

Version: 2.0 Date: October 25, 2004)

For the transfer of alternative sequences to the PDS the Badi CUSLNTRTO_ADDIN has to be

implemented (example coding in note 357178).

PPM

For the PPM the User-Exit CIFPPM01 had to be

implemented according to note 217210.
