GR error from production on RF

Hi All,

I have an error on the RF screen when I try to do the GR from production (See attached) rf-error.jpg I did the picking and the consumption on RF,worked great. and now this error appears at Good Receipt.

The path used on RF is: Rec HU by Manufacturing Order => Rec HU by order => Insert the manuf.order and then the error appears.. :/

Any ideas?
