Filling BPS_Value by Javascript

HI To everyone,

Hopefully someboday has an idea for this following problem.

Scenario:

I Have a Web Interface / Planning Application which has a an component of type SEL_VARVL which is assigned to a numerical bps variable ( and needs to be assigned to this nummerical bps variable) This vatiable field needs to be filled by a javascript, and should show the new value after the script has been executet.

Any idea?

Best Regards

Mike
