Hi Ibrahim,
I'm sorry but I cannot give you more detail because I don't have that app installed on my system.
What I mean is that I have solved that problem in several apps by doing two things (depending on the app):
a) Assigning the proper authorizations to objects in PFCG roles and re-generating the profiles.
b) Defining the values needed on transaction SIMGH.
I hope this can give you at least a clue to work on the solution of your issue.
Regards,
David.
