Answer / vamsi

In a general scenario, we cannot use two 01 level numbers in
the same structure.
We can use this when we want to redefines entire structure only.
Eg:
01 ws-input.
10 name pic x(40).
10 desig pic x(40).
01 ws-input-re redefines ws-input
10 name pic x(30).
10 department pic x(10).
10 designation pic x(20).
10 salary pic s9(13)v99.
10 filler pic x(13).

this way we can use.
