+# MPE_DATASTATUS_TABS
+
+The `MPE_DATASTATUS_TABS` table captures frequently changing SAS table attributes such as size (if filesystem based), modification date, and the number of observations.
+
+To trigger a scan, see the Refresh Data Catalog [instructions](https://docs.datacontroller.io/admin-services/#refresh-data-catalog).
+
+## Columns
+
+ - `TX_FROM num`: SCD2 open datetime 
+ - 🔑 `TX_TO num`: SCD2 close datetime
+ - 🔑 `LIBREF char(8)`: SAS Libref (8 chars)
+ - 🔑 `DSN char(64)`: The library member name
+ - `FILESIZE num`: The size of the table (in bytes), displayed with the SIZEKMG. format.  Only applicable to BASE engine libraries.
+ - `CRDATE num`: Creation date of the table
+ - `MODATE num`: Modification date of the table
+ - `NOBS num`: Number of Observations.  Note - if the table is a SAS dataset then this _includes_ deleted rows.  To remove deleted rows from a SAS dataset, it must be re-created.
