• What is the cause and solution for SAP error message PLM_SE_PRS_MESSAGES035 - NetworkRelationship: Predecessor activity must be the parent activity. ?

  The SAP error message PLM_SE_PRS_MESSAGES035 indicates that there is an issue with the relationship between activities in a project or process within the SAP Project Lifecycle Management (PLM) module. Specifically, the error states that a predecessor activity must be a parent activity, meaning that the predecessor activity you are trying to link is not correctly positioned in the hierarchy of activities.
  Cause:
  This error typically occurs due to one of the following reasons:
  
  Incorrect Activity Hierarchy: The predecessor activity you are trying to set is not a direct parent of the successor activity. In project management, a predecessor must be a higher-level task that must be completed before the successor can begin.
  Misconfiguration: There may be a misconfiguration in the project structure or the way activities are defined.
  Data Entry Error: There could be a simple data entry error where the wrong activity is selected as a predecessor.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Activity Hierarchy:
  
  Review the hierarchy of the activities involved. Ensure that the predecessor activity is indeed a parent of the successor activity.
  You can do this by navigating to the project structure and verifying the relationships between the activities.
  
  
  
  Adjust Relationships:
  
  If the predecessor is not a parent, you may need to adjust the project structure to ensure that the correct parent-child relationships are established.
  You can either change the predecessor to a valid parent activity or restructure the activities to reflect the correct hierarchy.
  
  
  
  Re-enter Data:
  
  If you suspect a data entry error, re-enter the predecessor activity to ensure that the correct one is selected.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on setting up activity relationships correctly.
