Hi,
To get Navigational attributes to enable in Infoset , you need to add master data Info object of that respactive nav.attibute and join and finally enable Nav attributes.
Suppose :
To enable Navigatinal attribute of 0MATERIAL - 0MAT_TYPE.
You need to add 0MATERIAL into Infoset and Join it to DSO.
Then enable 0MAT_TYPE.
Regards,
Vijay
