Hello,
Currently
LineItem objects do not have a way to retrieve the progress of a line item via API. In
reportService you can run a report with dimension attribute
LINE_ITEM_DELIVERY_INDICATOR but that will only give you the following percentages for a line items progress:
100% - The LineItem is on track to deliver in full as per LineItem.unitsBought.
> 100% - The LineItem is on track to overdeliver.
< 100% - The LineItem is on track to underdeliver.
N/A - The LineItem does not have any quantity goals, or there is insufficient information about the LineItem.
