• What is the cause and solution for SAP error message CJ193 - Selct one or more project objects of the same type ?

  The SAP error message CJ193 ("Select one or more project objects of the same type") typically occurs in the context of project management within SAP, particularly when working with project structures in transactions related to project planning, such as CJ20N (Project Builder) or CJ40 (Project Planning).
  Cause:
  This error arises when you attempt to perform an action (like copying, deleting, or changing) on multiple project objects (like WBS elements, networks, or activities) that are not of the same type. For example, if you select a WBS element and a network at the same time, SAP will not allow the operation because these are different types of project objects.
  Solution:
  To resolve this error, you should ensure that you are selecting only one type of project object at a time. Here are the steps you can take:
  
  
  Review Your Selection: Check the objects you have selected in the transaction. Make sure they are all of the same type (e.g., all WBS elements or all networks).
  
  
  Select Individually: If you need to perform an operation on different types of objects, do it one type at a time. For example, first, select all WBS elements and perform the desired action, then do the same for networks or activities.
  
  
  Use Filters: If you are working with a large number of project objects, consider using filters to narrow down your selection to a single type.
  
  
  Check for Mixed Selections: If you are using a selection screen or a list, ensure that you are not inadvertently mixing different types of project objects.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ20N (Project Builder), CJ40 (Project Planning), and CJ30 (Project Budgeting) to understand where this error might occur.
  SAP Documentation: Refer to SAP Help documentation for detailed information on project management and the specific transactions you are using.
  User Authorizations: Ensure that you have the necessary authorizations to perform actions on the selected project objects, as sometimes authorization issues can lead to unexpected errors.
  
  By following these steps, you should be able to resolve the CJ193 error and continue working with your project objects in SAP.
