BEx Designer: How to count if an InfoObject(field=ProblemNr) is empty

Question

Hi,
in the ROWS i have an InfoObject (let's say ProblemNumber) and in the COLUMNS another InfoObject (Date).
The IO in the Rows is not a primary key and it's not always filled in. The OrderNr might be a primary key.
I want to find out how many of the entries in a specific month (IO Date) have ProblemNr and how many not.
So basically would lool like the following:
                              April
With ProblemNr:    25
W/o Problem Nr:   18
Would you give me tips how i can show such a result.
Thank you!

Answer 1

I have two Field in the Multiprovider: DocNumber & DeliveryDate.
In the Query Design I created a Count (Calculated Key Figure) to count the entries
since Iu2019m not allowed to change anything in the Data Model.
The DocNumber might and might not have a DeliveryDate, Ex:
DocNumber     DeliveryDate 
1234               12.03.11
2345                    --
4567                11.01.10
6789                01.05.11
So i need to design a Query to count Number of Documents (DocNumber ) that have
No(Empty) DeliveryDate  & also Number of Documents (DocNumber ) that
have DeliveryDate.
So the result would look like something like this:
                              April    May    June   July
No DeliveryDate     54       23          22         56
With DeliveryDate   32       3             52         26
So there are 54 Documents that have DeliveryDate Field empty and
32 Documents with DeliveryDate filled in.
