Please see my scenario below and help me if you can.
Step 1 : Excel file has data columns A to P
Step 2 : Column P Filter : remove rows which has “abcd”
Step 3 : Get the values from Column D (Multiple rows are there , non static number of rows)
Step 4 : Need to process each of the values of Column D on website portal.
Step 5 : IF process success then Update the value on same row but column P.
Step 6 : Else Need to update “Error” on same row but column P.
While iterating through the data table, you can update column P after you perform a condition check on column D.
If you face any Concurrent access exception then probably you can create a variable with DataRow and assign it with the current row then update column P based on your check.
