Hi , i dont reallt get what u mean,
but the main thing is you want to stop the process if robot find particular value on the table right?,
then you can use for each tor ead each row of datable,
then inside for each activity use" if activity"
’ use a condition if row(“columname”) = “value you want to find”’
THEN
'you can stop it using"Message box activity"/“STOP activity”,
Else
“dont put anything on else”
