How to find which levels are not used in Demantra

Hi All,

When i see business modeler, i can see less number of levels, where as in t_src_item_tmpl, i will see multiple columns and mostly sending N/A data. now we had one requirement to add a level and how to make use of these existing ones. can see in staging table and these are not seen in business modeler. how to map these two?

based on some doc, instead of going new level, existing unused level needs to be used.

regards

Mahesh
