Pricing at time of goods receipt not possible for this item

Question

We're receiving error Message no. 06634 Pricing at time of goods receipt not possible for this item when trying to change the PO Pricing Date Category from No Control to 5 GR Date.
The error message is clear and reads:
Pricing at time of goods receipt not possible for this item
Message no. 06634
Diagnosis
For this purchasing document item, you wish to specify that a new price determination process is to be carried out at the time of goods receipt.
System Response
Pricing cannot be carried out for the item at the time of goods receipt because the price was either entered manually or copied from the last purchasing document.
The scenario is that we have a contract reference on a PO and the contract condition records are to be maintained as a new price is valid each day.  The problem without this is that the new pricing will not be reflected in the GR.
What is the solution to overcome this issue?
NOTE:  the Info Record conditions are not being read during GR as the PO references a contract.

Answer 1

For further clarification the PO is referencing a contract and as such not pulling the pricing information from the info record and instead pulling the price from the conditions on the contract. 
I want to change the pricing date category from " No Control" to "5 GR Date" however I'm receiving the error message stated and unsure of how to make this change.
The intent is not to create a new PO each day the condition record is created and instead we are utilizing one PO referencing one contract with multiple date delimited condition records containing the daily pricing.
