Production (October 2020 - PUBLISHED) vs Pre-Production (March 2021) VERSION 4 traceability

Differences found in package Comparison	Number of records impacted	Rationale
SimpleMap files	282	33 new SimpleMap records + 249 inactivated records, ALMOST as expected as confirmed by Donna in the May 2020 - October 2020 months (inclusive) in the spreadsheet: https://docs.google.com/spreadsheets/d/1IzI2iZTNXKIh8jVVMy5wFByHFlb-Dy_ivw38Wg8Pe9E/edit#gid=123726236 TOTAL = 33 records added + 263 records removed SADLY DOES NOT QUITE RECONCILE WITH DELTA FROM WCI WHICH PROVIDES: TOTAL = 33 records added + 249 records removed Have asked Donna for an answer…. Donna confirmed probably just a few out because of the new report WCI have added into the report generator to allow her to check where a SNOMED concept is inactive yet a GMDN code exists and so the mapping tool has these in the map record. Donna therefore signed off discrepancy as expected. + spot-checked by AAT by comparing actual changes against SimpleMap Delta file provided by WCI + confirmed with the totals in the WCI Delta file + GDMNStats.txt report
ModuleDependency files	2	2 new March 2021 records added as expected
Readme file	n/a	Updated with all March 2021 dates as expected
