• What is the cause and solution for SAP error message /SAPAPO/RRP_HEUR646 - &1 dependent orders are deleted ?

  The SAP error message /SAPAPO/RRP_HEUR646 indicates that a certain number of dependent orders have been deleted during the planning process in SAP Advanced Planning and Optimization (APO). This typically occurs in the context of production planning and scheduling, where dependent orders are linked to a parent order or a production plan.
  Cause:
  
  Order Deletion: The error usually arises when the planning heuristics or algorithms determine that certain dependent orders are no longer valid or necessary. This can happen due to changes in demand, capacity constraints, or adjustments in the production schedule.
  Data Inconsistencies: There may be inconsistencies in the master data, such as incorrect BOM (Bill of Materials) or routing information, leading to the deletion of dependent orders.
  Planning Parameters: The settings in the planning run, such as the heuristics used, may be configured in a way that results in the deletion of dependent orders.
  Resource Constraints: If resources are not available or are over-allocated, the system may delete dependent orders to optimize the planning process.
  
  Solution:
  
  Review Planning Parameters: Check the settings of the planning heuristics being used. Ensure that they are configured correctly to meet your production requirements.
  Check Master Data: Verify the accuracy of the master data, including BOMs, routings, and resource availability. Correct any inconsistencies that may lead to the deletion of orders.
  Analyze Demand Changes: Look into any recent changes in demand that may have triggered the deletion of dependent orders. Adjust the planning accordingly.
  Run Planning Again: After making necessary adjustments, rerun the planning heuristics to see if the issue persists.
  Consult Logs: Check the planning logs for more detailed information about why the dependent orders were deleted. This can provide insights into specific issues that need to be addressed.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like /SAPAPO/RRP3 to analyze the planning results and see the status of orders.
