Here are the steps to enable DFF's on OAF pages. You can do this for any OAF page in Oracle Apps R12.
Start by adding a DFF to Create Purchase Order page in Buyer Work Center. First we need to define the DFF. The steps are as follows:
1. Create a new Value Set.
2. Define Values for the value set created in step 1.
3. Add Value Set to the Flex Field Segment in Application: Purchasing and Title: PO Headers.
4. Freeze and Compile the FlexField definition.
Enable this DFF in Buyer Work Center. the steps are as follows:
1. Enable profile Personalize Self-Service Defn to yes at the user level.
2. Click Personalize Page at the top of the Create Purchase Order page.
3. Look for Flex: (HeaderRN.DescFlexfields)
4. Click Edit (Pencil)
5. Chang Rendered from false to true

One more example: Add DFF to iProcurement Requisition header in the same way. Define a DFF again:
1. Create a new Value Set.
2. Define Values for the value set created in step 1.
3. Add Value Set to the Flex Field Segment in Application: Purchasing and Title: ReqExpress Headers.
4. Freeze and Compile the FlexField definition.
