Calendar input help in web layout

Hi Community,

I have a BPS web interface with a planning layout for input of date, which has been generated by the means of bps_wb. This layout uses key figure of type date in data columns.

If I execute the layout in BPS0 the calendar input help pop-up (F4) comes automatically, which is not the case in web.

Is this a bug or lack of functionality?

I just want to be sure if OSS call is legitim.

Many thanks for any info!
