Hi @Amin, I’m not sure I understand your topic but: have you tried activity “Filter Data Table”? You can filter multiple columns from one datatable variable (not from 2 variables unfortunately).
this is sample of the excel file,.
for example
240369411000 have multiple row data.
when ever i used look up range, the result will indicate same cell for those 5 row
you can always loop the table with the “For Each Row” activity and then check if the value is a specific one, with an “IF” activity. Would this work?
