Has ever anybody used and worked with the mass resource maintenance in APO within the /SAPAPO/RES01 ?
Since no any hint in the related help.sap.com, OSS, a step by step guide would be appreciated by the whole APO community.
No, I we are not interested about the MASSD, since this has no such options like the RES01 would offer. Like the mass Capacity or Shift seq. assignment.
The screenshots below shows what suppose to work: --> EXACTLY HOW? 
thanks in advance
