SET_TABLE_FOR_FIRST_DISPLAY and HotSpots

Hello,
We have a report that uses SET_TABLE_FOR_FIRST_DISPLAY which works well but I have been asked to add a hotspot to call another screen. I see that a fieldcatalog can be passed but I have not found a method that corresponds to REUSE_ALV_FIELDCATALOG_MERGE.
I am a novice at method programming and did think that using the FM was the correct thing to do. Is there was a method that would do the same thing? Does anyone have some sample code?
Thank you in advance.
Regards, Dean.

Hi Dean,
There is no harm in OOALV, But I would suggest you to go for the OOALV.
Now a days a new feature has provided by SAP regarding ALV which is SALV.
I have created a sample program corresponding to almost all funcitonality.
just copy and paste this program you will see the difference how easy is OOALV (SALV).
