How to make a field readonly when certain field value changes from the oldvalue ?

[ABHI08]

Need to make a field readonly when the value changes for the first time to avoid multiple changes

Hi @ABHI08 

You need combination, server side with client side 

1 - Business Rule (Server-side)

Create a Business Rule to detect first-time change:

• Table: your target table (e.g., incident)
• When: before
• Update: (checked)
• Condition: Leave blank or add any condition you want

if (!current.u_priority_changed && current.priority.changes()) {
current.u_priority_changed = true;
}

2 - UI Policy to Make Field Read-Only (Client Side)

Create a UI Policy to make the short_description (example field) read-only when the flag is true:

• Table: your target table (e.g., incident)
• Conditions:
  
• u_priority_changed is true
• In the UI Policy Actions:
  
• Field: short_description
• Read-only: (checked)

@Ankur Bawiskar I want to make a field read only after after the field value have been changed once. The read-only part is only to avoid any further changes to the field value after the 1st time change

1st time change for new record or existing record?
