• What is the cause and solution for SAP error message 5W655 - No relationship found ?

  The SAP error message 5W655: No relationship found typically occurs in the context of SAP's Project System (PS) or when dealing with network activities and dependencies. This error indicates that the system could not find a valid relationship between the objects you are trying to work with, such as tasks, activities, or other project elements.
  Causes:
  
  Missing Relationships: The most common cause is that the required relationships (dependencies) between tasks or activities have not been defined in the project structure.
  Incorrect Configuration: The project or network might not be configured correctly, leading to missing links between activities.
  Data Inconsistencies: There may be inconsistencies in the data, such as deleted or inactive activities that are still referenced.

  Data Consistency Check: Run a consistency check on the project or network to identify any inconsistencies or errors in the data. This can often be done through transaction codes like CJEN (for project structures) or CN22 (for networks).
  Review Authorizations: Ensure that you have the necessary authorizations to view and modify the project or network. If you suspect authorization issues, contact your SAP security team.
