Customer Change Team Leader


This change seeks to reject replacement Meter Reads, using an existing rejection code, provided by either the DMSP or Shipper User where the read date is prior to the current LIS date. 

The LIS date is set each year and estimated reads are generated for 01/04/YYYY where no reading(s) exist for 3 years prior to the new LIS date and no reading exists after this date. Therefore, where there is no estimated or actual LIS read, then the read immediately prior to the LIS date will remain a valid read to be replaced and subject to all other read validations and reconciliation/invoicing processes. In these cases, re-reconciliation will be triggered to correct the post LIS period, only.
