Can We Use SAP-APO-DP And SAP-APO-PPDS (DO NOT FEEL NEED OF SAP-APO-SNP)

[Former Member]

We are in process of finalising the modules to be opted for SAP-APO. On analysing, we found that SAP-APO-DP and SAP-APO-PPDS are the modules of our interest. But only at one point, we are feeling the use of SAP-APO-SNP. i.e. capacity levelling. We wants to know that how does capacity levelling can be taken care of in PPDS without doing SNP Capacity Levelling in SNP.

Kindly Confirm.

Dinesh,

You can level capacity/dispatch orders in Detailed scheduling, much the same way you would do in R/3, using the DS planning board. You can also run DS heuristics as part of your planning run to automate the process. To accomplish these tasks, you do not need SNP.

Dinesh,

Details of how to set up and execute capacity leveling would require a small book. Basically, the Master data required are the Resource data (like R/3 Work Center capacities) and the Production Process models (alternatively the Production Data Structures)(like R/3 routings&BOMs). The general gist of the most common approach is that you first execute an infinite plan using an MRP-type PP heuristic. Then, you Run a finite Detailed Scheduling heuristic, such as Schedule Sequence. In the detailed scheduling of the orders, your DS heuristic adjusts the dates of the planned orders in an attempt to completely fill in under-utilized resources, and reduce the loads of over-loaded resources.

If you have ever cap leveled in R/3 after an MRP run, the process will be very familiar to you. My opinion is that PPDS will give you a more accurate picture of capacity consumption than SNP (some people may disagree), but the setup, and the ongoing master data maintenance for PPDS is substantial. The results of a PPDS MRP/Cap leveling run should yield an executable plan without further adjustment.

and topics in the same general area of SCM help gives an overview of the major points of finite scheduling in DS.
