• What is the cause and solution for SAP error message IU853 - ICNV lock could not be executed -> Is deleted as candidate ?

  The SAP error message IU853, which states "ICNV lock could not be executed -> Is deleted as candidate," typically occurs in the context of the SAP Integrated Business Planning (IBP) or SAP Advanced Planning and Optimization (APO) systems. This error is related to the handling of locks on data objects during planning activities, particularly when there are issues with the data consistency or when a lock cannot be acquired for a specific object.
  Cause:
  
  
  Data Locking Issues: The error often arises when the system is unable to acquire a lock on a data object because it is already locked by another process or user. This can happen during planning runs, data uploads, or when multiple users are trying to access the same data simultaneously.
  
  
  Deleted Candidates: The message indicates that the system has identified a candidate for processing that has been marked as deleted. This could occur if a planning object was removed or if there was an inconsistency in the data.
  
  
  Configuration Issues: There may be configuration issues in the planning area or in the settings related to the data locks.
  
  
  Solution:
  
  
  Check Locks: Use transaction codes like SM12 to check for existing locks on the relevant data objects. If you find locks that are no longer needed, you can delete them (if you have the necessary authorizations).
  
  
  Review Data Consistency: Ensure that the data being processed is consistent and that there are no deleted or invalid entries in the planning area. You may need to run consistency checks or data validation processes.
  
  
  Reprocess the Planning Run: If the error occurred during a planning run, try to reprocess the run after resolving any locking issues or data inconsistencies.
  
  
  Adjust Configuration: Review the configuration settings related to the planning area and data locks. Ensure that they are set up correctly to avoid conflicts.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of SAP you are using. There may be specific patches or updates that address this issue.
  
  
  Contact SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP support for further assistance. They may provide insights based on the specific context of your system.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM12 (for lock entries), SM21 (for system logs), and SLG1 (for application logs) to help diagnose the issue.
  SAP Notes: Search for SAP Notes related to IU853 or data locking issues in the SAP Support Portal. These notes may provide additional troubleshooting steps or known issues.
  User Authorizations: Ensure that users have the appropriate authorizations to access and modify the data objects involved in the planning process.
