Get first value and then remove remaining in query output

Question

hi all,
we have a query where we want to count the number of sales orders and show this count by created on month and salesperson.  trick is that sales orders have multiple line items so the same order can show in multiple months. 
lets say order 1000 has 3 line items.  each item is for month 1,2 and 3 of 2009.  the report is showing as such:
1.2009 1
2.2009 1
3.2009 1
each value represents the same order number.  we only want to see 1.2009 and then 2 and 3 show nothing because the counting of the order should happen 1X.  so the first month it finds an order number in, it counts it for that month and if it finds the same order for a later month then don't count it.
is there a way to accomplish this?
thank you

Hi there,
If you simply want to create count on sales order, then in query designer, just create a calculated key figure in that use option of formula variable,
create one new formula variable of processing type replacement path and assign that sales order number characteristic to reference characteristic.
in next replacement path tab
Replace variable with - Infoobject
Replace with  - Attributes
Attributes - characteristic reference.
For calculated key figure use aggregation after option.
Hope this will help you.
