• What is the cause and solution for SAP error message CJ008 - Choose only one WBS element (PR...) ?

  The SAP error message CJ008 ("Choose only one WBS element (PR...)") typically occurs when you are trying to assign or process multiple Work Breakdown Structure (WBS) elements in a context where only one is allowed. This can happen in various transactions related to project management, such as when creating or modifying purchase requisitions, purchase orders, or other project-related documents.
  Cause:
  The error is triggered when the system detects that multiple WBS elements have been selected or entered in a field that only allows a single WBS element. This can happen due to:
  
  Multiple Selections: You may have inadvertently selected multiple WBS elements in a selection screen or input field.
  Incorrect Input: You might have entered multiple WBS elements separated by commas or spaces in a single input field.
  System Configuration: The configuration of the transaction or the specific field may be set to accept only one WBS element.
  
  Solution:
  To resolve the CJ008 error, you can take the following steps:
  
  
  Select a Single WBS Element: Ensure that you are only selecting or entering one WBS element in the relevant field. If you have multiple WBS elements, choose the one that is appropriate for your transaction.
  
  
  Check Input Format: If you are manually entering a WBS element, make sure that you are not including any delimiters (like commas or spaces) that could cause the system to interpret it as multiple entries.
  
  
  Review Transaction Settings: If you are using a custom transaction or report, check if there are any settings or configurations that might be causing this issue. You may need to consult with your SAP administrator or technical team.
