RAP Fiori Elements filter required

[Former Member]

Hello together,

I want to develop a RAP app whose list is output only after entering a filter. The classic mandatory approach will not work here, because this would require that a value be specified in each filter field for all filters. I have four filter fields and at least one needs to be filled, not all.

Can something like this be realized?

Bonus:

If no filter contains a value, a popup should appear with the request to specify at least one filter.

Hi,

It is not possible to achieve this with annotations. One way you could do this is by returning a backend transition message once the Go is fired - the same should be then shown by fe in a message dialog to alert the user that at least one the of fields should be filled.

At which point in the RAP model can I intercept the Go button in the backend?
