An issue has been identified where an 867_03F is received on a cancelled MVO, which was cancelled due to a same day MVI. The 867_03F should have been sent referencing the MVI instead.
Next Step:
Changes were made to the Stacking Logic to allow the TDSP to decide whether to accept a cancel on MVOs depending on whether they have been worked. Change Control 758 was written to allow the TDSP to reject an 814_08 cancel on any MVO that was already worked.

Review Stacking Documentation to see whether there is need to change the Implementation Guide or just the Stacking Documentation.

867_03F
Description:
This issue is a result of the faster timelines for completing AMS MVOs and the MVO has been completed before ERCOT sends the cancellation. When the TDSP runs their batch update that evening the 867_03F goes out but is for the MVO since they actually completed it and then completed a separate MVI.
Reason:
Incorrect reference in this transaction is causing system exceptions and resulting in rejects of the 867_03F.
