Hi,
1. Transcation code : OMET - Function authorization
in that, there is one check box called REF TO PURCHASE REQUISTION under the section of possible reference object (2nd from top). Activate this check box.
Assign this Function authorization key to the user profile.
Now onwards, this specific user cann't create PO with out PR. 
PR is mandatory for the PO creation for this user only. But other users can create PO, with out PR also.
This is user level control
2. Transcation: OMEC
Select your document type and   note down some where filed selection key which is maintained for your document type.
Transcation code :OMF4
Navigation path : Spro-Materials Management-Purchasing-Purchase Order-Define Screen Layout at Document Level
Select field selection key, which is identified in the first step and click on the details icon.
Click on the "Reference data, item"
set Purchase requisition as required (mandatory) entry.
Now onwards, you cann't create PO with out PR number.
This control is applicable for all the users. But for your document type only, which is used in the first step.
For what are the document types used this field selection key, you can't create PO with out PR number.
For other document types you can create PR with out PR number also.
