NOTICE DATE: July 6, 2012 NOTICE TYPE: R-A070612-01 – Extracts SHORT DESCRIPTION: TDSP ESIID Extract – AMS Indicator Defect INTENDED AUDIENCE: CRs and TDSPs DAYS AFFECTED: June 12, 2012; June 18, 2012; June 25, 2012; July 2, 2012; July 3, 2012 LONG DESCRIPTION: Texas Set 4.0 changes included the addition of the TDSP_AMS_INDICATOR column to account for the AMSR and AMSM values. ERCOT has identified a defect which allows the value of R to be populated in this column as well. Rows with the R value should indicate premises where AMS meter existed but has been removed. ERCOT will update the code to prohibit the R values from populating in the TDSP ESIID Extract in a future release. Until the change is implemented, market participants should treat the value of R in the TDSP_AMS_INDICATOR column as a null value.
