There is no need to have two object reference for the ALV (E_object) and (GRID).

You are first creating the object for the GRID and than using the same parent, you are creating the object E_OBJECT. This might clear the link between GRID and CON. Comment out the portion where you are creating object E_OBJECT.

For reference check: BCALV_GRID_DEMO

hi thank you namesh...

[Former Member]

First you need to create a container at se51 for holding data at runtime.

those you alredy created with name of CONT.

after that we need to create grid and in this grid we pass

the container name those we created in object point of view (con)

in this way we provide the link between our program to container.

and finally we call method grid->set_table_for_first_display

and pass the structure name 'MARA' and changing (it_outtab) = itab.

no need to create any thing apart from this.

plz do this i hope you get the output.

best regards:

mahesh, Its showing dump yar.Please send me the documents and steps to create containers in alv using ooabap.Please kindly request you to send me atleast links.It would be a lot privilege to me.

[Former Member]

same code is working in my system correctly. might be you are not creating the container at se51.

just you double click on 100.

set screen 100

system open a module pool screen and click on LAYOUT.

just double click on second last button on left side (when u place the cursor the name is howing custum container) after that u see one image like envalope . just u double click on this image give the name container1 at attribute. and save check activate. came back and there u see MODULE STATUS_1001. and MODULE USER_COMMAND_1001. just uncomment this module and save check activate.

and finally came back to abap code and save check activate.

this should be work (bcoz in my system it is runs perfectly)
