Infopath-Webservices-SQL server

[swethabilla]

Hi !

I created an infopath form which talks with the SQL server via
webservice.
I have 2 tables in the database Customer and Product ,with ID being
the primary key in the Customer table through which it links to the
product table.

I cascaded the tables for the delete and insert operations.(both in
SQL server and while creating the dataset")

Now , when I query from the Infopath form, all the records are
displayed however when I try to submit a new record it gives an error
as follows...

" SoapException: server was unable to read request ---

System.InvalidOperationException: Nested table "Product" which

inherits its namespace cannot have multiple parent tables in
different namespaces".

Can anyone tell me how to fix this problem.??
Thanks.
