Showing a Schema Map From a List View

[Jim Coyne]

NOTE: There's a newer version of this tool

"Show Schema Map" Tools

You should take a look at it instead of continuing on with this outdated post.

Mark Stanger has a great article over on the ServiceNowGuru site which explains how to create a UI Action that will popup a schema map to show you the table relationships from a form. It's a great tool and I use it constantly, but I've always thought it would be helpful to do it from a list view as well.

So, I created a Context Menu (https://wiki.servicenow.com/index.php?title=Context_Menus) that does the trick, even on related lists:




Here is how you set it up:

Table: Global [global]
Menu: List Header
Type: Action
Name: Show Schema Map
Condition: gs.hasRole("admin")
Order: 100000

Action Script:
u_showSchemaMapFromList();

function u_showSchemaMapFromList() {
   getTopWindow().popupOpenFocus('schema_map2.do?sysparm_stack=no&sysparm_attributes=table=' + g_list.tableName, 'super_schema', 950, 700, '', false, false);
}
