This error indicates that a conversion length has not been defined for a specific data type conversion operation.
  Cause:
  The error can arise in the following scenarios:
  
  Data Type Mismatch: When trying to convert a data type (e.g., from a character string to a numeric type) without specifying the necessary conversion length.
  Incorrect Use of Conversion Functions: Using conversion functions (like CONVERT_TO_STRING, CONVERT_TO_INTEGER, etc.) without providing the required parameters.

        lv_string TYPE string.
  
  lv_number = 12345.
  lv_string = CONDENSE( lv_number ).  " Ensure proper conversion
  
  
  Check Data Declarations: Review your variable declarations to ensure that all fields have appropriate lengths defined. For example:
  DATA: lv_char TYPE c LENGTH 10.  " Specify length
  
  
  Review Conversion Functions: If you are using any conversion functions, check the documentation to ensure you are using them correctly and providing all required parameters.
