HI haritha,
Navigational attribute is used for drilling down in the report. We don't need to maintain Navigational attribute in the cube as a characteristic (that is the advantage) to drill down
0MATERIAL has a Display attribute called MATGROUP and a Navigational attribute called MATTYPE.
If you want your report to show MATGROUP, you need to have 0MATERIAL in the query too. A Display attribute always 'tags' along with the 'parent' characteristic.
However you can include MATTYPE in your report without using 0MATERIAL. For reporting purposes a navigational attribute behaves just like another characteristic. This means that you can also have variables for navigational attributes.
One drawback is that since they are stored outside your Info Cube (in master data tables), the OLAP has to perform an extra step to pull in this data and this leads to some performance impact, although in most cases this is negligible.
When you double click on a cell in a report which contains a characteristic value, the report is filtered for this value and the entire characteristic column is removed from the results area. If you double click on material 1001, the material column goes away from the results and in the filter cells above the report, you can see value 1001 against Material.
If you double click on a key figure value, nothing
happens.
If you double click on a Char column heading, the char is removed from the drill down.
If you double click on a key figure column heading, all key figures go away, and the values that are left are for the key figure you double clicked. Again you can verify this by looking at the filter cells against the key figure structure.
