• What is the cause and solution for SAP error message CNV_PE_CHECK291 - Dynamic assign to field &1 of table &2 failed ?

  The SAP error message "CNV_PE_CHECK291 Dynamic assign to field &1 of table &2 failed" typically occurs during data migration or conversion processes, particularly when using the SAP Conversion Tools or during the execution of programs that involve dynamic field assignments. This error indicates that the system attempted to dynamically assign a value to a field in a specified table, but the assignment failed, likely due to one of the following reasons:
  Causes:
  
  Field Not Found: The specified field (&1) does not exist in the specified table (&2). This could be due to a typo or because the field has been removed or renamed in the current version of the table.
  Data Type Mismatch: The data type of the value being assigned does not match the data type of the target field. For example, trying to assign a string to a numeric field.
  Field Visibility: The field may not be visible or accessible in the current context, possibly due to authorization issues or because it is not included in the data dictionary for the current user session.
  Table Structure Changes: If the table structure has changed (e.g., during an upgrade or modification), the program may be trying to access fields that no longer exist or have been altered.
  
  Solutions:
  
  Check Field and Table Names: Verify that the field name and table name are correct. Ensure there are no typos and that the field exists in the specified table.
  Review Data Types: Ensure that the data type of the value being assigned matches the data type of the target field. If necessary, convert the data to the appropriate type before assignment.
  Check Authorizations: Ensure that the user executing the program has the necessary authorizations to access the specified field in the table.
  Review Table Structure: If the error occurred after a system upgrade or modification, review the table structure in the data dictionary (SE11) to confirm that the field is still present and has not been changed.
  Debugging: If you have access to the ABAP code, you can debug the program to identify the exact point of failure and gather more context about the values being assigned.
  
  Related Information:
