Regarding ALV

Former Member — Tue, 20 Jun 2006 21:41:56 GMT

Hi,

Can someone please tell me something about following:

What is the use of defining CLASS LCL_EVENT_RECEIVER DEFINITION DEFERRED ?

Also can someone tell me where I can get details about Various function modules we use in ALV ? I tried using help.sap.com but didn't find it ?

This is a definition of a local class which is used to recieve the events from your ALV grid which as been implemented as CL_GUI_ALV_GRID.

THe actual statement CLASS LCL_EVENT_RECEIVER DEFINITION DEFERRED means that you can reference the LCL_EVENT_RECEIVER before you actually define it in the code. This comes in handy when having your definitions in a separate include program and having your TYPE REF TO statements in your TOP include program.

Actually I already had that.

What I was asking was is there any documentation where they lists all the functions we use in ALV like resuse_alv_list_display, reuse_alv_events_get, resue_alv_block_list_display, etc.....

Well, now I think we are talking about two different things. The REUSE function modules is the Function Module way of implementing the ALV Grid. I thought that we were discussing CL_GUI_ALV_GRID which is the OO way of implementing. I would suggest getting to know the OO way as it provides better functionality and ease of use.

As far as the REUSE function modules.... do a search in SE37 for REUSE* This will give you all of them.

You can check out some of the examples, look at programs that start with BCALV
