You can use a Business Rule to update the field automatically when a record is created or updated.

Steps:

1. Go to System Definition → Business Rules.

2. Create a new Business Rule on the required table.

3. Set When to Before and choose Insert and/or Update depending on when you want it to run.

4. Add a Condition if the update should only happen under certain circumstances.

5. In the Script, set the field value.

Example:

(function executeRule(current, previous) {
    // Automatically set var to 'new value'
     current.var = 'new value';
})(current, previous);

Hello @surajsengar ,

Configure Before Insert/Update BR on the target table.

(function executeRule(current, previous /*null when async*/) {

    if (condition) {
        current.active = true;
    }

})(current, previous);

Note : Using a Before BR is considered best practice because it avoids additional database updates and improves performance.

Hello @surajsengar ,

Use before update/insert business rule , add required condition then use below code snippet

(function executeRule(current, previous) {
     current.your_variableName = RequiredValue;
})(current, previous);

When you use before update/insert business rule, at that time above logic will set required value and it will inserted/updated automatically.

If this helps you then mark it as helpful and accept as solution.
