Dear experts,
Please could you kindly help us with this issue:
We have created an Internal Project using Create Internal Projects app (F1656).
We now need to assign a Resourse to Work Packages:

But when we try to add a Resourse there is no one available to pick up for an assignement.
We have created several empoyees for this assignement using Import Employee app.
Employees are assigned to the same Service Organization as Project (Combination of Cost Center & Company Code)
All created Employees have Service Cost Level Assignement.

Please could someone kindly help us to understand why cant we assign those Employees as a Resourse to Internal Project?
