• What is the cause and solution for SAP error message AQV721 - An icon can only be assigned to an icon field ?

  The SAP error message AQV721, which states "An icon can only be assigned to an icon field," typically occurs when there is an attempt to assign an icon to a field that is not designated to hold an icon. This error is often encountered in the context of SAP GUI programming, particularly when working with screen elements in ABAP (Advanced Business Application Programming).
  Cause:
  The error is caused by trying to assign an icon (usually a graphical representation) to a field that is not defined as an icon field in the screen layout. In SAP, certain fields are specifically designated to display icons, and if you attempt to assign an icon to a standard text field or any other non-icon field, this error will be triggered.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Field Definition: Ensure that the field you are trying to assign the icon to is defined as an icon field in the screen layout. You can do this by checking the screen attributes in the Screen Painter (SE80 or SE41).
  
  
  Use the Correct Field Type: If the field is not an icon field, you will need to either:
  
  Change the field type to an icon field if appropriate.
  Use a different field that is already defined as an icon field for your icon assignment.
  
  
  
  Review Icon Assignment Code: Look at the ABAP code where the icon assignment is made. Ensure that the assignment is being made to the correct field type. For example, if you are using the SET ICON statement, make sure it is being applied to a field that can accept an icon.
  
  
  Testing: After making the necessary changes, test the screen or program to ensure that the error no longer occurs.
