Old and new OO based ALV

[Former Member]

Hi,

What are the advantages of new oo based alv grid over the older function module based version?

In new version, we need to define a screen to keep the container.

If I do not want to define a screen, can I still use the older version?

How do I create a field catalog automatically ( i.e. from a dictionary table) in older version?

Can I have a mix of these 2?

Thanks,

Rupalee.

There are many advantages of the OO as opposed using the FM. I prefer to answer your specific questions. Yes, you can continue to use FM, and if your field catalog is only the list of fields from data dictionary structure/table, you can just specify this in the I_STRUCTURE_NAME field.

Advantage in the case of OO based ALV is you have various methods related to ALV which can help modify the ALV Screen or maintain the screen in a better and easier way.

You can still use the Old FM.

'REUSE_ALV_FIELDCATALOG_MERGE': will help you build field catalog for old version.

You cannot have Mix
