The main usage of a Master Selection Formula in Zaapit for Salesforce is as a powerful rule that helps users automatically determine the master (or survivor) record when duplicates exist.
๐ก What It Does
When multiple records share similar or identical data, Zaapit uses the Master Selection Formula to auto-select the one that should be kept as the master record, while marking others as duplicates.
This ensures consistency, accuracy, and control in your deduplication process.

๐งญ To create a formula do the following:
๐งญ Step 1: Go to Object Manager
- Click the โ๏ธ Setup icon (top right corner).
- Select Object Manager.
- Choose the object you want to add the formula to, for example, Opportunity or Custom Object.
๐งฎ Step 2: Create a New Formula Field
- In the objectโs sidebar, click Fields & Relationships.
- Click New.
- Choose Formula as the type, then click Next.
- Enter:
- Field Label (e.g., Expected Close Date)
- Field Name (auto-fills)
- Formula Return Type โ select Date/Text/any
- Click Next.
๐ง Step 3: Write the Formula
In the formula editor, enter your logic using Salesforce formula syntax.
Exmaple: IF( IsPrimary__c = TRUE, “Master”, “Duplicate” )
tep 4: Check Syntax and Save
Click Save.
Click Check Syntax to validate your formula.
Click Next, set field-level security as needed (admin only), and no need to add it to your page layouts (it will be used inside the merge job).
You can disblae & clone an existing job to chnage the master selection formula:
