f you just want to display message (not block submit):

👉 Service Catalog → Catalog UI Policies

But UI Policy alone cannot stop submit — only client script can.

Best Practice (Enterprise)

ServiceNow architects typically:

• Use Catalog Client Script for hard validation

• Keep Order Guides generic

• Apply logic at Item level

This keeps Order Guides reusable.

Hello @Harika Thota ,

We have one method in client script :

g_cart.setQuantity(2);

This will automatically set the quantity mentioned :
