Product Catalogs on eCustomer application
For example:
Catalog: 123
Category: ABC
Product: Test
When the eCustomer application is launched you can see Catalog 123 and Category ABC. If you drilldown on ABC you can see some of the products in this particular catalog/category and in fact none of the products listed there are in the catalog/category.
The same behavior does not occur in the sales application. When launching sales application you can see Catalog 123 and Category ABC. If you drilldown on ABC only the product defined for this catalog/category is showing up, using the example above, only product Test is displayed.
