3. Introductions

MCT discussions:

-       Currently the AMS Indicator (REF~MR) in the Implementation Guide shows multiple REF~MR can be sent in the same transaction.  ERCOT is suggesting this be updated to only allow 1 per transaction.

o   If multiple are sent to ERCOT they will not know what to display on TML

o   ERCOT would like to receive REP input on receiving multiple REF~MR in the same transaction. 

§  What would you do? 

§  Would you expect ERCOT to reject so you only receive 1?  Or would you store both?
