Requisition – Form 1116A (Optional Form)

Form number 1116A is optional for county purchasing agents who choose to utilize a separate form for requisitions instead of utilizing the top portion of form 1116. The purpose of this form is to streamline the requisition process.
19 O.S. § 1505(A)(l) 

1. The form may be filled in and digitally signed by an authorized requisition official so that it may be emailed to the purchasing agent. Adobe will walk the user through the process of setting up a digital signature.
   Note: 
   Digital signatures should be protected by passwords and stored in safe locations to prevent unauthorized use.
2. Alternatively, the form may be filled in, printed, and then signed manually so that it may be scanned, emailed, faxed, or hand delivered to the purchasing agent.
3. Once the requisition is approved, the purchasing agent will fill in the bottom portion of the form, send a copy to the requisitioning department, and then attach the original to the purchase order. The purchasing agent shall then make a note on the top portion of form 1116 referencing the attached requisition.
4. After the requisition is approved and funds encumbered, the purchase may be processed in accordance with county policy and statutes.
