Is there any activity which adds a validation column to the input file for the records that have been successfully processed and the records that have failed. Something like Yes/No?
What are the activities which would perform this activity?
In this case using IsMatch activity could be better option here,
So using proper regex pattern in this activity, and output variable will give, a boolean variable that is true if the regular expression finds a match, else false.
Then, using —> bool.Tostring=“true” (Condition) in If activity you can able to write correct findings accordingly (Yes in Then & No in Else) using write cell OR Assign and then write range.
