Select month using specific date fields

[fgirardin]

Hello,

I'm trying to show documents that have been created on a specific date in my ERP

Table looks like this

If I select a month using the calendar data, I can see every documents created this month but, since I have 3 fields with dates (dd.mm.yyyy) it will only display datas from the month I selected

If I select "MARCH" on my calendar, the result will be:

I would like to be able to show ALL documents with shipping date = march

I've tried to select dates from the document_shipping_date field. This field use the "dd.mm.yyy" date format. If not converted to dates, the datas look like this

Is there a way to select "Shipping Dates" = March so it displays all shipping documents and order / invoice documents related ?

Let me know if my question is not clear

Thank you !

After checking your link, I'm not sure I can use this solution as the field "Date" is used by all 3 document types (order,shipping, invoice)

What I did on my table to separate the dates is use the following expression (1 for each document type): 

=only({<DOC.Type_document = {'Shipping'}>} DOC.Date_document))

Is it possible to load the dates separately in my script ?
