Creating a Request from OATi webOASIS ATC Offerings

Creating a Request from the OATi webOASIS ATC Offerings Using OATi webOASIS to create a TSR from ATC Offerings MW Amount will default to the full Capacity Available for that Increment (in this case the daily amount of firm available is 232MW)

Creating a Request from OATi webSweep ATC Offerings Clicking on the PostingRef brings the user to the Offering for the specified Service, Path & Term. The offering is for the full Capacity Available for that Increment. User access to webSweep is through OATi ETS

Creating a Request from WebSweep ATC Offerings Creating a TSR from the Offering Detail returns to a TSR Entry form with a Blank or Null MW field.

Creating a Request from OATi ATC Offerings Given the demonstration of the tools, is there sufficient value to warrant asking for a change?
