Inability to edit or delete sales order or Opportunity products in the SalesLogix 7.5.4 web client

If you are running IIS 7 there is an important step you need to do in order to allow the SalesLogix web client to edit or delete products from both the Opportunity and Sales order product’s tabs.

Since the Product’s tab uses client side SData calls,  these calls can’t work right if the All Verbs setting isn’t set on the ‘SimpleHandlerFactory-ISAPI-2.0’.  

The Implementation guide has you set All Verbs, and create the Wildcard mapping on the SData portal.  Apparently this works in IIS6, but in order for the SLXClient portal to work completely in IIS 7, All Verbs needs to be set there too.
