Hi All,

Here i am trying to share some important things, which needs to be asked while doing SCM server sizing exercise, off-course actual scenario varies from one business to business, but some ground rule stays.

Then we always have quick sizer from SAP itself.

Here we go;

MODULE: DP

Total
Start of processing time of DP user End of processing time of DP user

MODULE:SNP and PPDS
