used this functions

REUSE_ALV_BLOCK_LIST_INIT'

inside loop and enloop itab header.

REUSE_ALV_BLOCK_LIST_APPEND'

and then

REUSE_ALV_BLOCK_LIST_DISPLAY'

the report function right with one material, but no with much materials.

I can' t use the function 'REUSE_ALV_HIERSEQ_LIST_DISPLAY because the reporte have many columns.

Please give me reward points if it is useful...

These FMs used for the BLOCKs list.

BLOCK list is if you want differnet ALVs with different Fieldcatalog in the same screen than you can use these FMs.

REUSE_ALV_BLOCK_LIST_INIT - To start the Blockked list

REUSE_ALV_BLOCK_LIST_APPEND - To append the lists into the screen, you may have to use this FM more than once as per your requirment of ALV

REUSE_ALV_BLOSK_LIST_DISPLAY - TO dispaly all appended blocks ...

Hi,

REUSE_ALV_BLOCK_LIST_INIT

This is for initializing the block list output. But if you check the function module documentation, you will see that the function module has not actually been "released" yet. So SAP recommends that you do not use it.

REUSE_ALV_BLOCK_LIST_APPEND

If you want to create the blocked alv then first you have to initialise the block then you can append one by one

REUSE_ALV_BLOSK_LIST_DISPLAY

you have to call the funciton module for dipslay

Regards,

Priyanka.

Hi,

Check the sample program BALVBT01 which uses the function modules

REUSE_ALV_BLOCK_LIST_APPEND

REUSE_ALV_BLOCK_LIST_DISPLAY

Have a look at the following sample reports:

ZUS_SDN_TWO_ALV_GRIDS

ZUS_SDN_THREE_ALV_GRIDS

And if you need more than two or three ALV grids then have a look at my sample report ZUS_SDN_SPLITTER_CONTAINER in thread

Max no of ALV grid's in single screen?

Regards

This looks like a simple report but this report has the features of sorting and filtering only.

The important functions used in this report are:

A. REUSE_ALV_BLOCK_LIST_INIT

B. REUSE_ALV_BLOCK_LIST_APPEND

C. REUSE_ALV_BLOCK_LIST_DISPLAY

A. REUSE_ALV_BLOCK_LIST_INIT

This function module is used to set the default gui status etc.

B. REUSE_ALV_BLOCK_LIST_APPEND

This function module adds the data to the block.

C. REUSE_ALV_BLOCK_LIST_DISPLAY

This function module display the list with data appended by the above function.
