ABAP OO context for dynamic data

Hi Team,

I am having a small problem. I did this kind of things earlier but I dont know for some reason I was not able to do this now.

I have a WA declared like this in METHOD A.

DATA : CS_DATA TYPE REF TO DATA.

I enhanced SAP Standard Class and in METHOD B.

I need to assign the structure of the CS_DATA only when required fields come in METHOD B

Both METHOD A and B are called in three different classes N number of times.

For example there is a structure like XYZ and has Fields A,B,C.

I know the fields of the structure but not the structure name. It is very dynamic one.

so I need to capture the structure name in METHOD B so that I can assign that type to my field-symbol for further processing.

Please advice..
