Cannot save order due to credit block V1849

In VA01, when I try to craete a sales order with Production order/ plan order , I get an information message saying that 'Subsequent function not possible due to credit block.'

It is going into the incomplete logs and requires to provide details for purchase order requistion. That however we cannot complete as credit limit is exceeded.

But as per requirement, the order should be saved even if the credit limit exceeds though the message pops up. the message number is V1849. Can you please tell me how to do that? The purchase order req should be created after release of credit limit.

Switching off credit control for this order type is no solution.

Thanks

Hein
