What is the purpose of Catalog tab in Task List and PM order?

I find this in the component overview of orders and task lists. We maintained BOMs for equipment. We use catalogs for Notification.

How to use catalogs in the component overview of order?

Do we need to do some settings in material master?

Answer

If you are referring to the Catalog button at the bottom of the Components tab, then this is used to link to an internal/ external internet site where you can order spare parts.

Have a look in the PM IMG for OCI (under orders).
