Multiple External Lists in One External Content Type

Hi,

I am creating an HTML form in SharePoint 2013 where I need to populate some drop-down controls with values from different Tables from SQL Database.

I created an External Content Type and have included Read List and Read Item Operation for all the lists however I can have only one default operation for each operation type (Read, Modify, Delete and Create). If I try to populate a drop-down from the external list whose Read Operation is not the default then it gives the below error:

"No default finder found for ViewGroup associated with SpecificFinder (Read Item) operation {Operation Name} in EntityNamespace '{Site Url}, {External Content Type Name}'".

So if I need to populate 10 dropdown controls with each having a different data source (Table in Database) then I need to create 10 different External Content Types, one for each Table?

Thanks
