Step by Step Salesforce Tutorial – Creating Tab and Validation Rule – 3 of n

In this tutorial, we are going to create Tab and Validation rules for Automated tuition class registration.

To create Tab go to Setup -> Create -> Tabs -> New Custom object Tabs, and there select object Student.

After creation of tab, we can also customize / edit the page layout.

Now lets have a look in Validation feature of salesforce.

Validation rules verify that the data a user enters in a record meets the standards you specify before the user can save the record. A validation rule can contain a formula or expression that evaluates the data in one or more fields and returns a value of “True“ or “False.” Validation rules also include an error message to display to the user when the rule returns a value of “True” due to an invalid value.
To begin using validation rules, click Setup | Customize, select the appropriate activity, standard object, or users link from the menu, and click Validation Rules. For custom objects, click Setup | Create | Objects and select the custom object. Validation rules are listed in the Validation Rules related list.

Note : Validation rules apply to all new and updated records for an object, even if the fields referenced in the validation rule are not included in a page layout or an API call. If your organization has multiple page layouts for the object on which you create a validation rule, verify that the validation rule functions as intended on each layout. If your organization has any integrations that use this object, verify that the validation rule functions as intended for each integration.

In our scenario, lets say the installments cannot be less than 500.

    1. Using Validation rule, its not possible. You need to code either Trigger or any VF+Controller for on demand analysis.
