Variants functionality for a custom made report

Question

Hello everybody,
i want to integrate the variant functionality we all know from reports in a custom made report (Dynpro). Is there any kinda generic functionality available you can hook up with? Like FMs or something?
best regards,
Markus

Hello,
maybe i should start from the very beginning. I am developing an application/report which has besides standard input fields a table (editable Grid Control) as selection fields.
I started off using the selection-screen functionality and integrated the Grid Control as a subscreen. Working great. But as it come to developing the functionaility "variant saving" i went into a problem. The standard input field were covered by the SAP standard functionalities, but not the table (grid control).
What i managed to implement using the possibility of custom code at the standard events AT SELECTION-SCREEN and AT SELECTION-SCREEN OUTPUT was when you click on the save button in a report to save my table content in a own database table with the link to the name of the standard variant. (Systemfield VARI hold the data). I even was able to load my saved table data, when loading a variant. This worked only on the first run (event initialization), as clicking on the load variant button in a report does NOT give me any return-code, like pressing the save button. It just raises the event PBO, as does pressing the enter button. So my problem is, i do not have the info at runtime, whether someone has pressed the load variant button and selected a variant or whether someone just pressed the return key, both do invoke PBO and i cant tell the difference.
So i had the idea of instead of using a report, developing a own dynpro application (Module pool).
