Hi ​@Busra Akcan ,

You can select the Valid for Original Authorization option if you want the rule to be used for authorization of the original purchase order revision. You can learn more about Purchase Authorization and the functionality of its different checkboxes and fields via below link:
http://clouddocs/ifsdoc/Apps10/documentation/en/Procurement/AboutPurchaseAuthorization.htm?StandAlone=true

As far as I am aware, the standard functionality does not offer the ability to apply the purchase order authorization rule based on order creation date.

Hi ​@Busra Akcan , Agreeing with above comment and adding below information. 

Even if there were no authorization required at the point of order release, if a purchase order did not have any authorization fetched at order release but have a valid authorization at order arrival, authorization will be fetched. The purpose of having the purchase order authorization rule fetch at receipt is to make sure orders are not received without any authorization at all.

It is designed to perform purchase authorizations not only when receiving purchase orders but also when confirming. This is a feature in the complex Purchase Order Authorization functionality. If the purchase order is not authorized when released, then the system fetches a purchase order authorization rule which meets certain criteria and has the highest priority at the time of receipt. If there is not a single PO authorization rule active at that time then nothing will prevent the arrival.

Hope this helps.

Thanks,

Sayuri.
