You must have noticed that the Publication Date and the Order Date displays the Date & Time currently and it needs to be formatted for date only. This can be achieved using a formula field.
Right click on the Formula Fields option under the Field Explorer window, and select New.
Give your formula a name and this opens up the Formula Editor window where you can type in the actual date conversion formula. Note that the image shows the code required to extract the date alone from the PublicationDate Field.
Now replace the original PublicationDate field on the report with this formula field.
Now view the report in a browser and you will notice that the report is getting real close to what we saw initially (at least functionality wise).
