PO Receipt Error

Hi Experts,
When I try to do the PO receipt from Inventory or Purchasing responsibility the below error am getting

APP-FND-00804: Program error: Invalid arguments to the flexfield routines. Please inform your support representative that:

Routine FDFGST unable to find flexfield qualifier 4. The flexfield routines have been called incorrectly.

Make sure the flexfield qualifiers specified match those defined in the Register Key Flexfield form.

Kindly suggest me how to resolve this issue


Thanks
