• What is the cause and solution for SAP error message 50300 - Check only one field for each group ?

  The SAP error message "50300: Check only one field for each group" typically occurs in the context of data entry or configuration in SAP, particularly when dealing with fields that are grouped together in a selection screen or a configuration screen. This error indicates that the system expects only one field to be selected or filled in from a specific group of fields.
  Cause:
  The error is triggered when a user attempts to fill in or select multiple fields from a group that is designed to allow only one selection at a time. This is often seen in scenarios where fields are mutually exclusive, meaning that selecting one option makes the others irrelevant or invalid.

  To resolve this error, follow these steps:
  
  
  Identify the Group of Fields: Determine which fields are grouped together and causing the error. This can usually be found in the documentation or by examining the screen layout.
  
  
  Select Only One Field: Review the fields in the group and ensure that you only fill in or select one of them. Clear any other fields in that group that you may have inadvertently filled.
  
  
  Review Field Dependencies: If applicable, check if there are any dependencies or conditions that dictate which field should be filled based on other selections you have made.
  
  
  Consult Documentation: If you are unsure about which field to select, refer to the relevant SAP documentation or help resources for guidance on the specific transaction or configuration you are working with.
  
  
  Test Changes: After making the necessary adjustments, try to execute the transaction or save the configuration again to see if the error persists.
