Need to see total quantities from start date to end date

Hello,

At the end of the month I am asked to see how many machines were created in one month.

Example how many XYZ machines were created in Jan?

I use COOIS already, but when I try using the dates section nothing comes up, even when I look at a production order to see what date it was created.

I am just wondering if there is another t-code I can use.

Thank you for your help!
