 # Data Controller for SAS® - Troubleshooting
 
 ## Overview

 The reason is that the context chosen when importing the SPK (perhaps, SASApp) is not available to your business user.  It's likely you have multiple contexts.
 
-The SPK must be re-imported with the correct context chosen.  This may require regenerating the tables, or adjusting the permissions, if the new context uses a different system account.

+#### Change Tracking
+Currently, transactional changes made to tables in Data Controller are tracked by means of individual CSV files.  A user can navigate to the HISTORY tab, find their change, and download a zip file containing all relevant information such as the original excel that was uploaded, SAS logs, the change records (CSV) and the staging dataset.
+
+Whilst helpful for investigating individual changes, the mechanism does not curently exist for (easily) tracking changes to particular variables / records across time, nor for (easily) re-instating versions.
+
+A transaction table would fix this.  However, given that the number of changes could be quite large, this should be an optional (configurable) feature.
+
+The proposal is as follows:
+
+* Create a switch (new variable) in MPE_TABLES to enable tracking on a table-by-table basis
+* Create an MPE_AUDIT_HISTORY table to contain records of all changes to tracked tables
+
+Model Changes:
+
+```sas
+/* MPE_TABLES updates */
+proc sql;
+alter table dc.mpe_tables
+  add track_changes char(1);
+
+/* no PK defined as it is a transaction table */
+create table dc.mpe_audit_history(
+  load_id char(32),
+  processed_dttm num format=E8601DT26.6,
+  libref char(8),
+  dsn char(32),
+  key_hash char(32),
+  move_type char(1),
+  is_pk char(1),

+  oldval_num num,
