• What is the cause and solution for SAP error message /SAPAPO/PPM_MAINTAIN508 - Only link type end-start for successor of setup activity &1 &2 allowed ?

  The SAP error message /SAPAPO/PPM_MAINTAIN508 indicates that there is an issue with the link type defined for a successor of a setup activity in the Production Planning and Detailed Scheduling (PP/DS) module of SAP Advanced Planning and Optimization (APO). Specifically, the error states that only the "end-start" link type is allowed for successors of setup activities.
  Cause:
  This error typically occurs when:
  
  You are trying to create a successor activity for a setup activity using a link type other than "end-start." In PP/DS, setup activities must be followed by successor activities that start after the setup activity has ended.
  The configuration or planning setup in your system does not adhere to the required constraints for setup activities.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Link Types: Review the link types defined for the activities in question. Ensure that the successor activity is linked to the setup activity using the "end-start" link type. This means that the successor activity should start only after the setup activity has completed.
  
  
  Modify Activity Relationships:
  
  Go to the relevant planning board or transaction where you manage the activities.
  Identify the setup activity and its successor.
  Change the link type to "end-start" if it is currently set to a different type (e.g., "start-start," "end-end," etc.).
  
  
  
  Review Planning Parameters: Ensure that the planning parameters and settings for the production process are correctly configured to allow for the required link types.
  
  
  Consult Documentation: If you are unsure about how to change the link types or if the error persists, refer to the SAP documentation or help resources for guidance on managing activity relationships in PP/DS.
  
  
  Testing: After making the necessary changes, test the planning scenario again to ensure that the error no longer occurs.
