  The SAP error message /INCMD/MSG169 Group type is invalid; only FFF class, chains can be used to create PSP typically occurs in the context of Project System (PS) when trying to create a Work Breakdown Structure (WBS) element or a project structure that is not compatible with the specified group type.
  Cause:
  
  Invalid Group Type: The error indicates that the group type you are trying to use is not valid for the operation you are attempting. In SAP PS, only certain group types (specifically those of class FFF) are allowed for creating Project Structures (PSP).
  Configuration Issues: There may be configuration settings in the system that restrict the use of certain group types for project creation.
  Incorrect Master Data: The master data for the project or WBS element may not be set up correctly, leading to the use of an invalid group type.
  
  Solution:
  
  Check Group Type: Ensure that you are using a valid group type. For creating PSP elements, you should use group types that belong to the FFF class. You can check the group type in the project definition or WBS element you are trying to create.
  Review Configuration: If you have access to the configuration settings, review the settings for project types and group types in the Project System configuration (transaction code SPRO). Ensure that the group types you are using are allowed for the project type you are working with.
  Use Correct Class: If you are trying to create a project or WBS element, ensure that you are using the correct class (FFF) for the group type. If necessary, consult with your SAP administrator or functional consultant to verify the correct settings.
  Check Master Data: Review the master data associated with the project or WBS element. Ensure that all required fields are filled out correctly and that the group type is set to a valid value.
  Consult Documentation: If you are unsure about the group types and their classifications, refer to SAP documentation or help resources for guidance on valid group types for project structures.

  User Roles and Authorizations: Ensure that you have the necessary authorizations to create or modify project structures in SAP.
