Where shared logic belongs (one Integration Procedure reused by Omniscripts, Flexcards, Apex and Flow), how Omnistudio, Flow and Apex call each other, which package-era actions and batch jobs the Standard Runtime lacks, when Document Generation needs Omnistudio, and the benefits and limits of Business Rules Engine tools.

- Certification: Salesforce Omnistudio Consultant
- Exam section: Best Fit Solutions
- Study guide: https://www.certifyforce.com/study-guide/omnistudio-consultant

**Official exam objective:**

> Justify and recommend architectural choices, demonstrating how Omnistudio components fit into the overall Salesforce and enterprise system landscape.

## What the exam expects

- Recommend one Integration Procedure for shared, non-interactive logic that Omniscripts, Flexcards, Apex and Flow reuse.
- Explain how Omnistudio, Flow and Apex call each other instead of copying one rule into several components.
- Spot package-era capabilities the Standard Runtime doesn't have (Intelligence and OmniForm actions, Vlocity scheduled and batch jobs) and redesign around them.
- Use Integration Procedure actions that reach other services (Docusign Envelope, Chatter, Email) instead of rebuilding them.
- Decide whether Salesforce Document Generation needs Omnistudio.
- State the benefits and limits of Business Rules Engine tools, including effective-dated decision matrix versions.

Key terms: **Integration Procedure** (server-side actions, no user interaction); **Remote Action** (calls Apex or an invocable action); **Business Rules Engine** (expression sets plus lookup tables); **decision matrix** (inputs matched to a row); **decision table** (lookup over rule records); **expression set** (stepwise calculation).

## Check yourself

- Why should a Standard Runtime design reuse an existing invocable action through a Remote Action instead of rebuilding its rule in Omniscript formulas?
- When does Salesforce Document Generation need Omnistudio?
- Which permissions do matrix builders and runtime users need?
- When can a Salesforce Flow use a decision table without Omnistudio?
