• What is the cause and solution for SAP error message CNDP009 - CNDP: Only single-column CHAR tables can be sent as strings ?

  The SAP error message CNDP009 indicates that there is an issue with the data structure being sent to a function module or method that expects a single-column character (CHAR) table. This error typically arises when the data being passed does not conform to the expected format.
  Cause:
  The error occurs when:
  
  You are trying to pass a table that has multiple columns or a different data type (e.g., numeric, date) to a function that only accepts a single-column character table.
  The structure of the data being sent does not match the expected input format of the function module or method.
  
  Solution:
  To resolve the CNDP009 error, you can take the following steps:
  
  
  Check the Data Structure: Ensure that the table you are trying to send is indeed a single-column character table. You can do this by checking the definition of the table in your ABAP code.
  
  
  Modify the Data Structure: If the table has multiple columns, you will need to create a new internal table that contains only the relevant single column. You can do this using a loop or a SELECT statement to extract the required data.
  Example:
  DATA: lt_source TYPE TABLE OF your_source_structure,
        lt_char_table TYPE TABLE OF char_field_type.
  
  LOOP AT lt_source INTO DATA(ls_source).
    APPEND ls_source-char_field TO lt_char_table.
  ENDLOOP.
  
  
  Use the Correct Function Module: Ensure that you are using the correct function module or method that matches the data structure you are working with. If the function requires a different format, you may need to find an alternative function that can handle your data.
  
  
  Check Documentation: Review the documentation for the function module or method you are calling to understand the expected input parameters and their types.
  
  
  Debugging: If you are still facing issues, consider using the debugger to inspect the data being passed to the function. This can help you identify any discrepancies in the data structure.
  
  
  Related Information:
  
  Function Modules: Familiarize yourself with the specific function modules or methods you are using, as they often have specific requirements for input parameters.
  Data Types: Understand the different data types in ABAP, especially CHAR, NUMC, DATS, etc., and how they can be converted or manipulated.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to the CNDP009 error.
  
  By following these steps, you should be able to resolve the CNDP009 error and ensure that your data is formatted correctly for the function you are trying to use.
