  The SAP error message SWDC122 indicates that there is an issue with the configuration of a table control in a screen (dynpro) where a column is being incorrectly defined as a "Radiogroup." This typically occurs in the context of SAP ABAP programming when designing user interfaces.
  Cause:
  The error arises when:
  
  A column in a table control is defined to use a radio button group (radiogroup), but the column does not meet the requirements for such a configuration.
  The column is not of a suitable data type or does not have the necessary attributes to function as a radiogroup.
  The radiogroup is not properly defined in the screen layout or the associated ABAP code.
  
  Solution:
  To resolve the SWDC122 error, you can take the following steps:
  
  
  Check Data Type: Ensure that the data type of the column you are trying to use as a radiogroup is compatible. Typically, it should be a character type (e.g., CHAR) that can hold the values representing the radio button options.

  Setting the RADIOBUTTON attribute for the relevant fields.
  Ensuring that the GROUP attribute is set correctly for the radio buttons to group them together.
  
  
  
  Review Table Control Configuration: Verify the configuration of the table control in the screen. Ensure that the column intended for the radiogroup is correctly set up and that it is not being used for other incompatible purposes.
  
  
  Check for Multiple Columns: If you are trying to use multiple columns as a radiogroup, ensure that they are all part of the same group and that the grouping is correctly defined.
  
  
  Debugging: If the issue persists, consider debugging the screen to see if there are any runtime errors or misconfigurations that could be causing the problem.
