SDP94 - Macro how to count the number of planned order for a bucket?

Hello All,

I'd like to create a ratio in which I could calculate the number of planned order in the bucket.

Would you have an idea to do this functionnality?

Ex:                                    Week 15.2015      16.2015     17.2015

Planned order                                   200          150               150    

Number Planned order                        4               3                    3

Thank's for you help
