Data Controller for SAS® - Options

The MPE_CONFIG table provides a number of system options, which apply to all users. The table may be re-purposed for other applications, so long as scopes beginning with "DC_" are avoided.

Currently used scopes include:

  • DC
  • DC_CATALOG

DC Scope

DC_EMAIL_ALERTS

Set to YES or NO to enable email alerts. This requires email options to be preconfigured (mail server etc).

DC_MAXOBS_WEBEDIT

By default, a maximum of 100 observations can be edited in the browser at one time. This number can be increased, but note that the following factors will impact performance:

  • Number of configured Validations
  • Browser type and version (works best in Chrome)
  • Number (and size) of columns
  • Speed of client machine (laptop/desktop)

DC_REQUEST_LOGS

On SASjs Server and SAS9 Server types, at the end of each DC SAS request, a record is added to the MPE_REQUESTS table. In some situations this can cause table locks. To prevent this issue from occuring, the DC_REQUEST_LOGS option can be set to NO (Default is YES).

DC_RESTRICT_EDITRECORD

Setting YES will prevent the EDIT RECORD dialog appearing in the EDIT screen by removing the "Edit Row" option in the right click menu, and the "ADD RECORD" button in the bottom left.

Anything other than YES will mean that the modal is available.

Default=NO

DC_RESTRICT_VIEWER

Set to YES to restrict the list of libraries and tables in VIEWER to only those explicitly set to VIEW in the MPE_SECURITY table. The default is NO (users can see all tables they already have permission to see).

DC_VIEWLIB_CHECK

Set to YES to enable library validity checking in viewLibs service. This means that on first load, SAS will attempt to open each library to see if it is possible to do so. This reduces the number of libraries in the list, but means that it is slow to load the first time around.

The default is NO.

DC_LOCALE

Set to a locale (such as en_gb or en_be) to override the system value (which may be derived from client browser settings). This feature is useful when importing ambiguous dates from CSV or Excel (eg 1/2/20 vs 2/1/20) as DC uses the anydtdtm. informats for import.

Default=SYSTEM.

Note

If you have clients in different geographies loading excel in local formats, you can also address this issue by ensuring the locale of the windows user profile is not set to the default (eg English (United States)). When leaving the DC_LOCALE as SYSTEM, the locale settings in SAS are not added or modified.

DC_CATALOG Scope

DC_IGNORELIBS

When running the Refresh Data Catalog service, it is often that case the the process will fail due to being unable to assign a library. To avoid the need to resolve the connection issue elsewhere in SAS, you can simply exclude it from the Data Catalog, by including the LIBREF in this field (pipe-separated)

DC_REVIEW Scope

HISTORY_ROWS

Number of rows to return for each HISTORY page. Default - 100. Increasing this will increase for all users. Using very large numbers here can result in a sluggish page load time. If you need large amounts of HISTORY data, it is generally better to extract it directly from the MPE_REVIEW table.
