Dynamic filter in BPC input form

Hi experts,

I have created in input form that contains the following dimensions :

Columns :

TIME (P1, P2, P3)

Lines :

PROFIT_CENTER (Profit center 1, Profit center 2)

DISTRIB_CHANNEL (Channel 1, Channel 2)

I need to display only channels that are related to each Profit Center.

For example, :

                                                     P1      P2       P3

Profit center 1        Channel1        

                             Channel2

Profit center 2        Channel3

                            Channel 4

The problem is that when I create the input form, I get all the Channels by Profit center which means :

                                                     P1      P2       P3

Profit center 1        Channel 1        

                            Channel 2

                            Channel 3

                            Channel 4

Profit center 2        Channel 1        

                            Channel 2

                            Channel 3

                            Channel 4

I have created a property Profit center in the dimension DISTRIB_CHANNEL to use the filter function in the input form but it's not working.

How can I perform this ? Is it possible to apply a dynamic filter or something ?

I'm working with SAP BPC 10.0 NW for HANA (CPMBPC 801 SP05 and EPM Add-in SP19)

Thanks
