Hi @VV7 ,
You can utilize the 'Charindex' function in expression as below:
Iif(Charindex(@label, 'labelname1') > 0 OR Charindex(@label, 'labelname2') > 0,'A1' ,Iif(Charindex(@label, 'labelname3') > 0 OR Charindex(@label, 'labelname4') > 0,'A2','A3' ) )
The above expression will result the value ...
