DG message """Dangerous goods master record is not released"

Hello Experts

I have referenced the Material into the specification in material reference and also maintained the DGP1.

The issue I face is when I create the delivery and try to pick it doens allow me throwing a DG message ""Dangerous goods master record is not released""

I tried to go to DGPREL and the product is released. So not sure what step I am missing?

Any ideas

thanks

SK
