• What is the cause and solution for SAP error message IAOM198 - Only one project definition can be maintained ?

  The SAP error message IAOM198: Only one project definition can be maintained typically occurs in the context of project management within SAP, particularly when dealing with project definitions in the Project System (PS) module. This error indicates that the system has detected an attempt to create or modify a project definition when there is already an existing project definition for the same project.
  Cause:
  
  Duplicate Project Definition: The most common cause of this error is that there is already an existing project definition for the project you are trying to create or modify. SAP allows only one project definition per project.
  Incorrect Project Number: You may be trying to create a project definition with a project number that is already in use.
  System Configuration: There may be specific configurations or settings in your SAP system that restrict the creation of multiple project definitions.
  
  Solution:
  
  
  Check Existing Project Definitions: 
  
  Navigate to the Project System (PS) module and check if a project definition already exists for the project number you are trying to use. You can do this by using transaction codes like CJ20N (Project Builder) or CJ03 (Display Project).
  
  
  
  Use the Existing Project Definition: 
  
  If a project definition already exists, you should use that existing definition for your project activities instead of trying to create a new one.
  
  
  
  Modify the Existing Project Definition: 
  
  If you need to make changes, you can modify the existing project definition rather than creating a new one.
  
  
  
  Consult with Your SAP Administrator: 
  
  If you believe that there should not be an existing project definition or if you need to create a new one for a valid reason, consult with your SAP administrator or support team. They may need to check the system settings or provide additional permissions.
  
  
  
  Review Documentation: 
  
  Check the SAP documentation or help files related to Project System for any specific guidelines or restrictions regarding project definitions.
