To view Dangerous goods in GTS

Dear Team,

We have not implemented EH&S module. But we have created a Ztable where we have maintained(Plant+material+UN-Number+DG goods indicator(Y/N).

And then we have implemented oss note-1365020 and we are using GTS version-10.1.

Now during my testing where can I see this DG indicator/UN number in SAP GTS ? Normally what value should come into GTS and how it works.

I checked table-/SAPSLL/LEGCUS as well as in customs document at item level in General Data Tab(Dangerous goods no.). No value is there ?

Thanks

Sits.
