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.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
