• What is the cause and solution for SAP error message LTR2_BASIS203 - Only character-like fields are allowed ?

  The SAP error message LTR2_BASIS203 ("Only character-like fields are allowed") typically occurs in the context of data processing or data transformation, particularly when working with data types in SAP systems. This error indicates that a field being processed is not of a character-like type (e.g., CHAR, STRING) when it is expected to be.
  Cause:
  
  Data Type Mismatch: The most common cause of this error is that a field being used in a function or operation is of a numeric or other non-character data type, while the operation expects a character-like field.
  Field Definition: The field may be defined incorrectly in the data structure or database table, leading to a mismatch when the system tries to process it.
  Data Transformation: If you are using data transformation tools (like LSMW, BAPIs, or custom ABAP programs), the mapping of fields may not be set up correctly, leading to this error.
  
  Solution:
  
  Check Field Types: Review the data structure or table definition to ensure that the fields being processed are defined as character-like types. You can do this by checking the data dictionary (SE11) for the relevant table or structure.
  Modify Data Mapping: If you are using a data transformation tool, ensure that the mapping of fields is correct. Make sure that numeric fields are not being passed to functions that expect character-like fields.
  Data Conversion: If necessary, convert the data type of the field to a character-like type before processing. In ABAP, you can use functions like CONCATENATE or WRITE to convert numeric values to strings.
  Debugging: If you are developing custom code, use the debugger to trace the values and types of the fields being processed at runtime. This can help identify where the mismatch is occurring.
