As seen below

Step 2: Grant a Permission

• Open the Permission Role for user whom you like to grant access to all jobs.
• Click on Permission
• Under Employee Data: Grant Permission
• Click on Save Changes.

Step 3: Create rule: use base object : Trigger onView Rules for HRIS Elements

1. Create Rule - View in Edit Mode

Note: Please refer to Rule Scenarios for Employee Central Core

use base object : Trigger onView Rules for HRIS Elements

• You can use this scenario to create rules that defaults the value for a field or change field properties or calculate fields that are transient (this means that the result is not a fixed value stored on the database but is calculated during rule execution when the user calls up the page). In Manage Business Configuration, rules created using this scenario can be used only for the onView event type.

View Rule

Step: Add Rule to Manage Business configuration or BCUI

• Click on employmentInfo

• Save

<hris-element id="employmentInfo">

<label>Employment Details</label>

<label xml:lang="en-US">Employment Details</label>

Example:

• Hire date: Jan 1, 1996

Q) Where can I get information on this from the Guide?

A) Guide:Implementing Employee Central Core   /     Chapter:Rule Scenarios for Employee Central Core

Q) Can I run a report on transient field?

A) Just a quick note on onView calculated fields:

• Calculated fields are transient fields, meaning they are not stored in the database.
• Instead, values are calculated dynamically each time you view a user’s Biographical Information.
• Because of this, these fields are not supported for reporting and will not be available in reports when the rule is set to trigger onView.
