Hi Ram,

    It depends on your scenario. For example, you can do the aggregation in Database itself before bringing to Talend if the source is a DB.

    If it is a sequence number, you can pick the last row's value will since it will be in ordered format.

     If it is in jumbled format, you will have to sort the entire record set using tSortrow and then pick the value of last record by assigning the value of each row to a context variable using tjavarow . Since the previous value will be overwritten when new row is processed, automatically you will get the last row's value once the entire data set is processed.

     I would suggest you to create a sample flow with the logic explained below to practice your learning. Could you please mark the topic as resolved since query has been answered? Kudos are also welcome 🙂

Warm Regards,
