• What is the cause and solution for SAP error message W_DSD_01052 - &1 supply relat. restored, &2 supply relat. terminated/deleted ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W_DSD_01052 &1 supply relat. restored, &2 supply relat. terminated/deleted
  
  Meaning / Cause:
  This warning message occurs in the SAP Demand Supply Determination (DSD) process, which is part of the Advanced Planning and Optimization (APO) module or the Supply Chain Management (SCM) system.
  
  &1 supply relationship restored: This indicates that a previously inactive or deleted supply relationship has been reactivated or restored during the supply network planning run.
  &2 supply relationship terminated/deleted: This indicates that a previously active supply relationship has been terminated or deleted during the planning run.
  
  Supply relationships define the connections between supply and demand locations (e.g., between a plant and a customer or between a supplier and a plant). These relationships are used by the system to determine feasible supply sources for demand elements.
  The message is informational/warning and typically appears during the supply network planning run or when the system updates the supply network based on master data changes or planning heuristics.
  
  Causes:
  
  
  Master Data Changes:
  
  Changes in supply relationships in the master data (e.g., product location master, supply network) can cause the system to restore or delete supply relationships during planning.
  
  
  Planning Heuristics or SNP Run:
  
  During the SNP (Supply Network Planning) run, the system may adjust supply relationships based on feasibility, constraints, or optimization results.
  
  
  Data Inconsistencies or Synchronization Issues:
  
  Sometimes, inconsistencies between master data and planning data can cause the system to restore or delete supply relationships.
  
  
  
  Solution / Actions:
  
  
  Check Master Data:
  
  Verify the supply relationships in the master data (e.g., product location master, supply network). Ensure that the relationships are correctly maintained and consistent.
  
  
  Review Planning Run Logs:
  
  Analyze the SNP or supply network planning run logs to understand why the system restored or deleted supply relationships.
  
  
  Consistency Checks:
  
  Run consistency checks for supply network data to identify and fix any inconsistencies.
  
  
  Adjust Planning Parameters:
  
  If the system is deleting supply relationships due to constraints or heuristics, review and adjust planning parameters or constraints.
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that address known issues with supply relationship handling in your SAP APO or SCM version.
  
  
  Monitor Impact:
  
  Since this is a warning, monitor the impact on planning results. If the restored or deleted supply relationships cause planning issues, further investigation is needed.
