• What is the cause and solution for SAP error message /SAPAPO/CDPSPRESENTA129 - Predecessor order selected ?

  The SAP error message /SAPAPO/CDPSPRESENTA129 indicates that a predecessor order has been selected in the context of a planning or scheduling operation in SAP Advanced Planning and Optimization (APO). This error typically arises when there is a conflict in the order scheduling due to dependencies between orders.
  Cause:
  The error occurs when:
  
  An order that is dependent on another order (predecessor) is being processed, but the predecessor order has not been completed or is not in a suitable state for the dependent order to proceed.
  The system is trying to schedule or process an order that cannot start until its predecessor has finished.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Order Status: Verify the status of the predecessor order. Ensure that it is completed or in a state that allows the dependent order to proceed.
  
  
  Adjust Scheduling: If the predecessor order is delayed, you may need to adjust the scheduling of the dependent order. This can involve rescheduling the dependent order to start after the predecessor order is completed.
  
  
  Review Dependencies: Check the dependencies between the orders. Ensure that the relationships are correctly defined in the system and that there are no unnecessary constraints.
  
  
  Use Transaction Codes: Utilize relevant transaction codes (like /SAPAPO/SDP94 for planning board) to analyze the orders and their dependencies. This can help you visualize the order flow and identify any issues.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on handling order dependencies in APO.
  
  
  Contact Support: If the issue persists and you cannot identify the cause, consider reaching out to your SAP support team or consulting with SAP experts for further assistance.
  
  
  Related Information:

  APO Configuration: Ensure that your APO system is configured correctly to handle order dependencies. This includes settings related to production planning and scheduling.
  Error Logs: Check system logs for additional error messages or warnings that may provide more context about the issue.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
