Hello Pavan

Have a look through the sample reports in package SLIS and check transaction SE83 (Reuse Library).

The reports are not well structured but quite reasonably documented (in the header section).

Regards

Uwe

Hello Pavan,

You cannot directly put data in container. for that you need to use some custom control like avl grid, tree view etc.

After loading custom control in container you and fill data in custom control and display the data.

Just to start with the custom control, You can try loading ALV grid in container.

Follow the link [ALV Grid|http://help.sap.com/saphelp_erp2004/helpdata/EN/22/a3f5ecd2fe11d2b467006094192fe3/frameset.htm] for more details.

Also you can follow link [Custom Container|http://help.sap.com/saphelp_erp2004/helpdata/EN/d3/2955360b00a115e10000009b38f839/frameset.htm] for more detail on types and usage of containers

Hope this helps!

Thanks,

Augsutin.

Hello Pavan,

Whatever code you have written is correct just need to change one little thing is while passing table also put [] for table body

as follow:

You need to select data into internal table before you call method SET_TABLE_FOR_FIRST_DISPLAY.

and if you change something on ALV then that part you need to handle in PAI event.

Check flow login documentation on SAP help.

CREATE OBJECT GRID1

EXPORTING I_PARENT = G_CUSTOM_CONTAINER.

CALL METHOD GRID1->SET_TABLE_FOR_FIRST_DISPLAY

EXPORTING

I_STRUCTURE_NAME = 'SFLIGHT'

CHANGING

IT_OUTTAB = GT_SFLIGHT[].

Hope this help!

Thanks,

Augustin.

Hello Pavan,

You can create structure using SFLIGHT table.

By the way I am not able to understand What you mean by you don't have strucuter?

You have structure right? SFLIGHT is the structure you are using to pass data either you can use that way or you can pass fieldcatalog table with the fields that you want to show in alv grid.

Follow the link provided in previous post and try building fieldcatalog with different methods like manually, automatic and semi-automatic fieldcatalog generation.

In your code below:


I_STRUCTURE_NAME = 'SFLIGHT'
CHANGING
IT_OUTTAB = GT_SFLIGHT[].

GT_SFLIGHT is internal table only and you must have defined that at the start of report. Right?

Normally steps in AVL report are:

1. Declare object and table variables

2. Prepare field catalog and layout tables

3. Register events

4. select data into internal table from required table

5. Create instance of alv class and call method to display data

Let me know if any issue,

Thanks,

Augustin.

Re: Regarding ABAP Through OOP

Hello,

You need to set OUTPUTLEN of fieldcatalog table for every column you are passing to fieldcatalog table

for example:



ls_fcat-fieldname = 'BNAME' .
ls_fcat-inttype = 'C' .
ls_fcat-outputlen = '12' .
ls_fcat-coltext = 'User Name' .
ls_fcat-seltext = 'User Name' .
APPEND lw_fcat to lt_fieldcat .

Hope this helps!

Thanks,

Augustin.

Hi, thanks

Can you please paste here the code for the below query(if possible),

select 2 or 3 fields from a database table (some MAKT), store them in an internal table, create a container and to display the fields of the internal table in that container using ALV

Thanks & Regards,

Pavan.
