Hello!
Hope you all have a great day.
So, I've been implementing Personnel Cost Planning and Simulation for a new system. To check how it all went I decided to run a test plan. In transactions PHCPDCEM and PHCPADMN everything went smoothly/ As a result I've got my plan as you can see on screenshot below.

Then I went to Detail Planning app. The problem is that I can't choose my plan in It.
I have all the needed roles, such as SAP_HR_CPS_DET_PLAN_D_SR_NWBC, SAP_HR_CPS_DET_PLAN_L_SR_NWBC, SAP_HR_CPS_HR-MANAGER and SAP_HR_CPS_MANAGER.
I've assigned an employee with a manager position, but still can't choose my plan.

What should I do?
Thank you in advance!
