Delivery scheduling ME38 / MIGO

Hi everyone.

We know, in the division of delivery schedule in ME38 transaction, we program the delivery date, on standard we can't do the MIGO in an period before the date programed in ME38.

But my customer need take it off this standard validation.

They need do the MIGO even if the delivery date has not been reached.

We have some way to do that on customizing?

Thanks for now.
