Hi ramanathan,
here i am giving the steps to enhance the datasource.
1. go to-> RSA6 selece ur datasource & click on the push button enhance extract structure
2. the system will propose a extract structure name which will prifix with ZA accept it
3. in the next screen enter the field name & componant type, make sure that the field name will start with ZZ.
4. save the structure & activate it.
5. now again go to RSA6
6. select the data source & say change. scroll to the bottom thr u will find ur field, by default hide option is selected, remove it flag the appropreate option & save it.
Up to here we added the field successfully.
Now we need to populate the field with data.
this needs the ABAP programme.
Sap provides sap enhancement RSAP0001.
You need to provide following information to ur ABAP colegue.
Datasource name
Extractstructure name
field name
table name
Infosource name.
He will write the functionmodule.
in ur case the exit is Exit_SAPLRSAP_002.
Hope this helps.
