When you need to upload many lines of the same type of information, such as in a table or a grid where the header stays the same and the line-item data changes, you can use a loop. The loop tells the script to process each row of line item data that is associated with the header data. Looping is applicable only in cases where line items are created on similar endpoints. In cases where looping is not applicable, you should record different scripts for each line item.
For instructions on adding a loop, see the following:
