# Column Level Security
|
|
|
|
Column level security is implemented by mapping _allowed_ columns to a list of SAS groups. In VIEW mode, only allowed columns are visible. In EDIT mode, allowed columns are _editable_ - the remaining columns are read-only.
|
|
|
|
## Configuration
|
|
|
|
The variables in MPE_COLUMN_LEVEL_SECURITY should be configured as follows:
|
|
|
|
### CLS_SCOPE
|
|
Determines whether the rule applies to the VIEW page, the EDIT page, or ALL pages.
|
|
|
|
- When applied to VIEW, then only allowed columns are _visible_
|
|
- When applied to EDIT, then only allowed columns are _editable_ (the remaining columns are read-only, and visible). Also, when CLS is applied in EDIT mode, the user will not be able to ADD or DELETE records.
|
|
|
|
### CLS_GROUP
|
|
The SAS Group to which the rule applies. The user could also be a member of a [DC group](/dcc-groups).
|
|
|
|
- If a user is in ANY of the groups, the columns will be restricted.
|
|
- If a user is in NONE of the groups, no restrictions apply (all columns available).
|
|
- If a user is in MULTIPLE groups, they will see all allowed columns across all groups.
|
|
|
|
### CLS_LIBREF
|
|
The library of the target table against which the security rule will be applied
|
|
|
|
### CLS_TABLE
|
|
The target table against which the security rule will be applied
|
|
|
|
### CLS_VARIABLE_NM
|
|
This is the name of the variable against which the security rule will be applied
|
|
|
|
### CLS_ACTIVE
|
|
If you would like this rule to be applied, be sure this value is set to 1.
|
|
|
|
|
|
## Example Config
|
|
Example values as follows:
|
|
|
|
|CLS_SCOPE:$4|CLS_GROUP:$64|CLS_LIBREF:$8| CLS_TABLE:$32|CLS_VARIABLE_NM:$32|CLS_ACTIVE:8.|
|
|
|---|---|---|---|---|---|
|
|
|EDIT|Group 1|MYLIB|MYDS|VAR_1|1|
|
|
|ALL|Group 1|MYLIB|MYDS|VAR_2|1|
|
|
|ALL|Group 2|MYLIB|MYDS|VAR_3|1|
|
|
|VIEW|Group 1|MYLIB|MYDS|VAR_4|1|
|
|
|
|
|
|
If a user is in Group 1, and viewing `MYLIB.MYDS` in EDIT mode, **all** columns will be visible but only the following columns will be editable:
|
|
|
|
* VAR_1
|
|
* VAR_2
|
|
|
|
The user will be unable to add or delete rows.
|
|
|
|
If the user is in both Group 1 AND Group 2, viewing `MYLIB.MYDS` in VIEW mode, **only** the following columns will be visible:
|
|
|
|
* VAR_2
|
|
* VAR_3
|
|
* VAR_4
