Report generation with custom link types

Hi,

I'm trying to achieve report generation with my custom link type "Mytype". The data for a my requirement type is in an sqlite database and I would like to write a custom "getter" because generateing a report now results in "Unable to resolve file"-error.

To my question: Which function should I implement in order to make the report fetch data from my database? Is it the ContentFcn? And in that case which out paramenter should contain the data which i want in the report?

Best regards

R
