• What is the cause and solution for SAP error message CNV_10020011 - Function module &1 doest not exist; check your input ?

  The SAP error message CNV_10020011 indicates that a function module specified in your input does not exist in the SAP system. This error typically arises during data migration or conversion processes, particularly when using SAP's Data Migration tools or during the execution of custom programs that rely on specific function modules.
  Cause:
  
  Non-existent Function Module: The function module specified in the input does not exist in the SAP system. This could be due to a typo in the name or the function module not being created or activated.
  Incorrect Input: The input provided to the program or transaction may be incorrect, leading to the system looking for a function module that is not valid.
  Missing Transport: If the function module was recently created or modified in a different system (like a development system) and has not been transported to the current system (like a quality or production system), it will not be available.
  Authorization Issues: Sometimes, the user executing the function may not have the necessary authorizations to access the function module, leading to the perception that it does not exist.
  
  Solution:
  
  Check Function Module Name: Verify that the function module name provided in the input is correct. Look for any typos or incorrect naming conventions.
  Search for Function Module: Use transaction SE37 (Function Builder) to search for the function module. If it does not exist, you may need to create it or check with your development team.
  Transport Check: If the function module exists in the development environment but not in the current environment, ensure that the transport request containing the function module has been released and imported into the target system.
  Authorization Check: Ensure that the user executing the transaction has the necessary authorizations to access the function module. You can check this using transaction SU53 after the error occurs.
  Consult Documentation: If the function module is part of a standard SAP package or solution, consult the relevant SAP documentation or support notes for any prerequisites or dependencies.
