• What is the cause and solution for SAP error message UPS1151 - Subplans &1 and &2 have &3 common nodes ?

  The SAP error message UPS1151 indicates that there is a conflict in the configuration of subplans within a project or process. Specifically, it states that two subplans (identified as &1 and &2) share a certain number of common nodes (indicated by &3). This can occur in various contexts, such as project management, production planning, or other areas where subplans are utilized.
  Cause:
  The error typically arises when:
  
  Overlapping Nodes: The two subplans have been defined in such a way that they include the same nodes or activities, which can lead to ambiguity in execution or reporting.
  Configuration Issues: There may be a misconfiguration in the way the subplans are set up, leading to unintended overlaps.
  Data Integrity Issues: There could be issues with the data integrity in the system, where nodes are incorrectly assigned to multiple subplans.
  
  Solution:
  To resolve the UPS1151 error, you can take the following steps:
  
  
  Review Subplan Definitions: Check the definitions of the subplans &1 and &2 to identify the common nodes. You can do this by navigating to the relevant configuration or planning transaction in SAP.
  
  
  Modify Subplans: If the common nodes are not intended to overlap, modify one or both of the subplans to eliminate the shared nodes. This may involve:
  
  Removing nodes from one of the subplans.
  Reassigning nodes to different subplans if they are meant to be exclusive.
  
  
  
  Consult Documentation: Refer to SAP documentation or guidelines related to the specific module you are working with (e.g., Project System, Production Planning) for best practices on defining subplans.
  
  
  Data Consistency Check: Run a data consistency check to ensure that there are no other underlying issues causing the overlap. This may involve checking for orphaned nodes or incorrect assignments.
  
  
  Testing: After making changes, test the configuration to ensure that the error is resolved and that the subplans function as intended.
  
  
  Seek Help: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide more tailored assistance.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Familiarize yourself with transaction codes related to subplan management in your specific SAP module (e.g., CJ20N for Project Management).
  User Forums: Engage with SAP community forums or user groups where similar issues may have been discussed, and solutions shared.
