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 the allowed columns are visible.
• When applied to EDIT, then only the allowed columns are editable (the remaining columns are read-only, and visible)

CLS_GROUP

The SAS Group to which the rule applies. The user could also be a member of a DC group.

• 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

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
