Field link on Grid not allowing link on fields

Applications Grid / Reports
#1

Would like to confirm whether I am doing this right?

Have a grid displaying information from a view, which contains grouping and subtotals.

Would like to create a field link to a control app which is expecting 2 parameters. The fields of the source grid app are not being shown as possible sources to link to the global variables on the control app.

Any feedback would be appreciated.

Any feedback would be appreciated from SC?

#3

What do you use to call your control app then? I guess you didnt look into sc_redir yet?
sc_redir (Application, Parameter01; Parameter02; Target, Error)
This macro its used to redirects to other application or URL.

Links > New Link > Chose Field > Chose Application > Link between Applications (Param definition) picks up the parameters that the destination application is expecting; chose FIELD and the list of fields from originating grid are not being listed?!
