description: Viewing and Modifying SAS Formats in Data Controller
---
!!! warning
Work in Progress!
# Formats
SAS Formats are stored in Catalogs, and are used for in-memory lookup operations. Some formats are available by default, others (custom formats) are maintained seperately.
Using Data Controller to manage formats means that it will no longer be necessary to maintain 'CNTLIN' datasets seperately to the main catalog.
Using Data Controller to manage formats avoids the need to maintain 'CNTLIN' datasets seperately to the main catalog.
Formats will be presented with a new icon (`bolt`), in the same library as other tables (in both the VIEW and EDIT screens):

Viewing a format catalog will always mean that the entire catalog is exported and displayed.
Viewing or editing a format catalog will always mean that the entire catalog is exported, before being filtered (if filters applied) and displayed. For this reason, it is recommended to split a large format catalog over several catalogs, if performance is a consideration.
Filters will be applied after the export. DDL / excel exports will apply to the export.
The usual export mechanisms can also be applied - you can downlad the DDL, or export the catalog in CSV / Excel / Datalines formats.
The MPE_TABLES for formats will need to be configured with a new LOADTYPE (FMTCATALOG) and specific CLOSE_VARS and BUSKEY values.
When adding a format to MPE_TABLES, the `DSN` should contain the format catalog name plus a `-FC` extension. The LOADTYPE should be `FORMAT_CAT` and the BUSKEY should be `FMTNAME START`. HOOK scripts can also be applied (run some DQ after an edit, or re-run a batch job after an approval).
Edits to formats will follow the regular approval process, with changes logged in MPE_AUDIT.
Just like regular table edits, all changes may also be logged in the `MPE_AUDIT` table.
