Data Controller for SAS® - DQ Validations¶
Overview¶
Quality in, Quality out! Data Controller lets you enforce quality checks at the point of data entry, both directly via the web interface and also via Excel uploads.
Default Checks¶
By default, the following frontend rules are always applied:
- Length checking per target table variable lengths
- Type checking per target table datatypes (Character, Numeric, Date, Time, Datetime)
- Not Null check per target table constraints
- Primary Key checking per business key defined in MPE_TABLES
It is possible to configure a number of other rules by updating the MPE_VALIDATIONS table. Simply set the BASE_LIB, BASE_DS and BASE_COL values, and ensure RULE_ACTIVE=1 for it to be applied.
Configurable Checks¶
Check back frequently as we plan to keep growing this list of checks.
| Rule Type | Example Value | Description |
|---|---|---|
| CASE | UPCASE | Will enforce the case of cell values. Valid values: UPCASE, LOWCASE, PROPCASE |
| NOTNULL | (defaultval) | Will prevent submission if null values are present. Optional - provide a default value. |
| MINVAL | 1 | Defines a minimum value for a numeric cell |
| MAXVAL | 1000000 | Defines a maximum value for a numeric cell |
| HARDSELECT | sashelp.class.name | A distinct list of values (max 1000) are taken from this library.member.column reference, and the value must be in this list. This list may be supplemented by entries in the MPE_SELECTBOX table. |
| SOFTSELECT | dcdemo.mpe_tables.libref | A distinct list of values (max 1000) are taken from this library.member.column reference, and the user-provided value may (or may not) be in this list. This list may be supplemented by entries in the MPE_SELECTBOX table. |
| HARDSELECT_HOOK | /logical/folder/stpname | A SAS service (STP or Viya Job) or a path to a SAS program on the filesystem. User provided values must be in this list. Cannot be used alongside a SOFTSELECT_HOOK. |
| SOFTSELECT_HOOK | /physical/path/program.sas | A SAS service (STP or Viya Job) or a path to a SAS program on the filesystem. User-provided values may (or may not) be in this list. Cannot be used alongside a HARDSELECT_HOOK. |
Dropdowns¶
There are now actually FIVE places where you can configure dropdowns!
- The MPE_SELECTBOX table
- The HARDSELECT validation (library.member.column reference)
- The SOFTSELECT validation (library.member.column reference)
- The HARDSELECT_HOOK validation (SAS Program)
- The SOFTSELECT_HOOK validation (SAS Program)
How do these inter-operate?
Well - if you have values in MPE_SELECTBOX and/or HARDSELECT / SOFTSELECT tables, they will be merged together, and served in ADDITION to the values provided by any HOOK program.
Dropdowns are SOFT by default, unless a HARD rule is present.
Data Controller will not let you submit both a HARDSELECT_HOOK and a SOFTSELECT_HOOK on the same variable.
