# Data Mapper scope, security and maintenance standards

*Omnistudio Consultant Study Guide · Data Mappers · Last updated October 27, 2026 · https://www.certifyforce.com/study-guide/omnistudio-consultant/data-mappers/data-mapper-scope-security-and-maintenance-standards*

The standards a consultant sets for Data Mappers: targeted scope combined in Integration Procedures, unique names and single mappings, a fixed Interface Type, Required Permission and its parent-IP gap, field-level security and encrypted fields, and the Data Mapper versioning source conflict.

- Certification: Salesforce Omnistudio Consultant
- Exam section: Data Mappers
- Study guide: https://www.certifyforce.com/study-guide/omnistudio-consultant

**Official exam objective:**

> Discuss best practices for Data Mappers.

## What the exam expects

- Recommend targeted Data Mappers combined in an Integration Procedure over one large Data Mapper shared by many callers.
- Set naming and mapping standards: unique output names, one mapping per target field with a formula for precedence, and query hierarchy kept in Extracts with a Transform for reshaping.
- Explain that the Interface Type is fixed at creation, so a type change means a new Data Mapper.
- Recommend Required Permission values, explain the blank-value default and why a parent Integration Procedure needs the same restriction.
- Recommend field-level security per Data Mapper or org-wide, and explain encrypted-field display by designer.

Key terms: **targeted Data Mapper** (extracts or loads only one operation's data); **Interface Type** (Extract, Turbo Extract, Load or Transform, chosen at creation); **Required Permission** (who can run a Data Mapper); **DefaultRequiredPermission** (the org-level fallback); **EnforceDMFLSAndDataEncryption** (Omni Interaction Configuration that enforces field-level security for all Data Mappers).

## Check yourself

- Why must a restricted Data Mapper's Required Permission also be set on the Integration Procedures that call it on Standard Runtime?
- When does a blank Required Permission let every user run a Data Mapper?
- Why should a field be mapped only once in a Load?
- When does selecting Check Field Level Security change a Data Mapper's caching on Standard Runtime?
