Selection Screen INFO : selinfo

Hi,

I am using the FM: RS_SELECTIONS_DESCRIPTION to read the selection screen structure.

The resulting List is of the structure selinfo. My system does'nt shows its documentation. I have trouble understanding its meaning.

The fields are :

1. name

2. Kind

3. type

4. Length

5. che_rad

6. id

7. nodi

8. Obligatory

I need to understand the significance of 5,6,7 and 8.

Thanks in Advance.

Ravi.
