Creating a Data Source for Linked Parameters

To implement linked parameters, you must first build a mobile business object that contains all of the dependent values, and a relationship between the values.

The mobile business object can use any data source, for example:

You must convert the data output from these data sources into a table of a specific format by using a transformation method, for example, using an XSLT template for the Web-service output, or using a stored procedure, or a formatted SQL query.

Required attribute names for linked parameters are:
For example, a correctly formatted SQL table looks like this:
CREATE TABLE "dba" . "linked_params" (
"index" INT NOT NULL ,
"display_name" VARCHAR (50) NOT NULL ,
"value_data" VARCHAR (50) NOT NULL ,
"value_name" VARCHAR (50) NOT NULL ,
"link" INT NOT NULL ,
)
IN SYSTEM
;
ALTER TABLE "dba" . "linked_params"
  ADD CONSTRAINT "ASA105" PRIMARY KEY CLUSTERED ( "index" )
;
ALTER TABLE "dba" . "linked_params"
  ADD CONSTRAINT "ASA106" UNIQUE NONCLUSTERED ( "index" )
;
