How To Fix PRP088 - You cannot staff role &2 with resource &1

SAP Error Message - Details

• Message type: E = Error

• Message class: PRP - Project Resource Planning: General Messages

• Message number: 088

• Message text: You cannot staff role &2 with resource &1

What causes this issue?

You want to staff role &V2& with user &V1&. This would enable the user
to have the authorization defined in the role type for all the project
elements to which this is assigned, if required.
However there is at least one project element below the project
definition (phase, task, or checklist) that cannot be locked because the
project element or a lower-level project element is already being
processed.

System Response

To prevent inconsistencies between staffing and the authorizations
assigned, the system does not allow the role to be staffed.

How to fix this error?

Try to staff the role again later on. This is possible once all the
phases, tasks, and checklists involved can be locked.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
