• What is the cause and solution for SAP error message RSSDA123 - Field &1: Conversion exit SNUMC does not support type DECIMAL FLOAT ?

  The SAP error message RSSDA123 indicates that there is an issue with the conversion exit SNUMC when it is applied to a field of type DECIMAL FLOAT. This error typically arises when there is an attempt to convert a decimal floating-point number using a conversion exit that is not designed to handle that data type.
  Cause:
  
  Data Type Mismatch: The SNUMC conversion exit is intended for character strings that represent numeric values, typically in a fixed-point format. When it encounters a DECIMAL FLOAT type, it cannot process it, leading to the error.
  Incorrect Field Definition: The field in question may be incorrectly defined in the data dictionary or in the program, leading to the use of an inappropriate conversion exit.
  
  Solution:
  
  Check Field Definition: Review the field definition in the data dictionary (SE11) to ensure that the field is defined with the correct data type. If the field is supposed to be a numeric type, consider changing it to a compatible type (e.g., DECIMAL or CHAR).
  Use Appropriate Conversion Exit: If you need to convert a DECIMAL FLOAT, you may need to implement a custom conversion routine or use a different conversion exit that supports DECIMAL FLOAT.
  Modify the Program Logic: If the conversion exit is being called in a program, check the logic to ensure that it is only applied to fields that are compatible with SNUMC. You may need to add checks or conditions to prevent the conversion exit from being applied to incompatible types.
  Consult Documentation: Review SAP documentation or help resources for more information on conversion exits and their appropriate usage.
  
  Related Information:
  
  Conversion Exits: These are routines in SAP that allow for the conversion of data between different formats. Each conversion exit is designed for specific data types.
  Data Types in SAP: Understanding the various data types in SAP (like CHAR, NUMC, DECIMAL, FLOAT) is crucial for proper data handling and avoiding type-related errors.
  Debugging: If you are unable to resolve the issue, consider using the debugger to trace where the error occurs and inspect the values being processed.
  
  If the problem persists after trying the above solutions, it may be beneficial to consult with an SAP technical consultant or refer to SAP support for further assistance.
