Hi,
Do not use roles provided in content provided from SAP, Instead use the roles that you have uploaded since you are trying to configure EHP 7 functionalities.
Only if you are using EHP6 functionalities , you can use the role present in folder content provided by SAP(roles founnd by deploying ESS MSS business packages).
This is what you are doing wrong.
Steps should be:
Activate WDA business functions.
* Activated all services.
* Created folder 100
* Upload PFGC ESS WDA roles from backend to Portal in these folders.
Check from help.sap the exact backend role for EHP 7 that is to be uploaded.
* Under Iview of ESS, overview -> right click --> properties --> Put system alias which you are using for client 100.
* Assigned same above roles to user of 100.
* In LPD _Cust, I made some services hidden by dragging it to inactive application and same changes are reflecting on portal - so I can make it out that my ESS roles are linked to LPD _cust roles because changes done in lpd are reflecting there.
First do this for client 100 and check.
Once this works, we wil check for 200 client.

Navya.
