Re: DG Goods Incompatibility.

1.Make sure you have Dangerous goods profile created from SPRO path -> SAP Transportation management -> Transportation management -> Basic functions -> Dangerous goods.

2. Assign this Dangerous goods profile to Freight unit type and Forwarding order type as well.

3. You should have incompatibilities created from Easy access -> Master data -> Application administration->Planning. This Incompatibility shall have Freight unit type assigned as a condition.

Please go through the below links.

Configuration of DG processing

Let me know if you stuck up somewhere or any specific question.
