• What is the cause and solution for SAP error message CPWB503 - Select one item only ?

  The SAP error message CPWB503 ("Select one item only") typically occurs in the context of the SAP Production Planning (PP) module, particularly when working with the Capacity Planning Workbench (CPWB). This error indicates that the system expects the user to select only one item for processing, but multiple items have been selected instead.
  Cause:
  
  Multiple Selections: The user has selected more than one item in a list or table where only a single item is allowed for the operation being performed.
  User Interface Limitation: Certain functions or operations in SAP are designed to work with a single item at a time, and selecting multiple items violates this requirement.
  
  Solution:
  
  Single Selection: Ensure that you only select one item from the list or table when prompted by the system. Deselect any additional items before proceeding.
  Review Functionality: Check the specific functionality you are trying to use and confirm that it indeed requires a single item. If you need to perform actions on multiple items, look for batch processing options or alternative methods that allow for multiple selections.
  User Training: If this error occurs frequently, consider providing training or documentation to users to help them understand the selection requirements for specific transactions.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with the relevant transaction codes in the Capacity Planning Workbench, such as CPWB, to understand where this error might occur.

  Documentation: Review the SAP Help documentation for the Capacity Planning Workbench to understand the limitations and requirements of the tool.
