• What is the cause and solution for SAP error message /PRA/ACCOUNTING335 - You cannot enter both WC and MP number ?

  The SAP error message /PRA/ACCOUNTING335: You cannot enter both WC and MP number typically occurs in the context of SAP's Project System (PS) or Controlling (CO) modules, particularly when dealing with work centers (WC) and maintenance plans (MP) in the context of project accounting or resource planning.
  Cause:
  This error arises when a user attempts to enter both a Work Center (WC) and a Maintenance Plan (MP) in a transaction or screen where only one of these entries is allowed. The system is designed to prevent the simultaneous entry of both types of identifiers because they serve different purposes and contexts in the system.
  Solution:
  To resolve this error, you should:
  
  
  Identify the Context: Determine where you are entering the data (e.g., in a transaction for project planning, resource allocation, etc.).
  
  
  Check Entries: Review the fields you are filling out. Ensure that you are only entering either a Work Center or a Maintenance Plan, but not both.
  
  
  Correct the Input: 
  
  If you need to use a Work Center, remove any entry in the Maintenance Plan field.
  If you need to use a Maintenance Plan, remove any entry in the Work Center field.
  
  
  
  Re-attempt the Transaction: After making the necessary adjustments, try to save or process the transaction again.
  
  
  Related Information:
  
  Documentation: Refer to SAP documentation or help files related to the specific module you are working in (e.g., Project System, Controlling) for more details on the use of Work Centers and Maintenance Plans.
  User Roles: Ensure that you have the appropriate permissions to make changes in the system, as some fields may be restricted based on user roles.
  Consult with Colleagues: If you are unsure about which entry to make, consult with a colleague or a supervisor who is familiar with the project or process you are working on.
