• What is the cause and solution for SAP error message /SAPAPO/TDL_DAO143 - An error occurred when saving LC planned orders ?

  The SAP error message /SAPAPO/TDL_DAO143 indicates that there was an issue when trying to save Local (LC) planned orders in the Advanced Planning and Optimization (APO) module. This error can arise due to various reasons, and understanding the cause is essential for finding a solution.
  Possible Causes:
  
  Data Inconsistencies: There may be inconsistencies in the data related to the planned orders, such as missing or incorrect master data (e.g., material master, resource master).
  Locking Issues: The planned order might be locked by another user or process, preventing the current transaction from saving changes.
  Configuration Issues: Incorrect configuration settings in the APO system can lead to errors when saving planned orders.
  Authorization Issues: The user may not have the necessary authorizations to save planned orders.
  System Performance: If the system is under heavy load, it may lead to timeouts or other issues when trying to save data.
  Transport Issues: If there are recent transports that have not been properly imported or have errors, this could affect the saving of planned orders.
  
  Solutions:
  
  Check Data Consistency: Verify that all relevant master data is complete and correct. Ensure that the materials, resources, and other related data are properly maintained.
  Release Locks: Check if the planned order is locked by another user. You can use transaction SM12 to view and release locks if necessary.
  Review Configuration: Ensure that the configuration settings in APO are correct. This may involve checking settings related to planning areas, planning books, and other relevant configurations.
  Check Authorizations: Ensure that the user has the necessary authorizations to create or modify planned orders. This can be checked using transaction SU53 after the error occurs.
  Monitor System Performance: Check the system performance and load. If the system is slow, consider optimizing performance or checking for background jobs that may be consuming resources.
  Review Transport Logs: If there have been recent transports, check the transport logs for any errors that may have occurred during the import process.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (to check locks), SU53 (to check authorizations), and ST22 (to check for dumps).
  SAP Notes: Search for SAP Notes related to this error message in the SAP Support Portal. There may be specific notes that address known issues or provide patches.
  Debugging: If the issue persists, consider debugging the process to identify the exact point of failure. This may require assistance from a technical consultant.
  
  If the problem continues after trying the above solutions, it may be beneficial to consult with your SAP Basis or APO support team for further investigation.
