Former Member — Sun, 16 Mar 2008 23:17:31 GMT

Hi Experts ,

I got 4 internal tables in my report . I have retrieved the data .

I should display the report in alv . How can i merge all the internal tables into single output table.

i want to print all the fields of my internal tables in single table.

thanks

For that you should have some common unique fields in all the internal tables. If so you can loop one internal table and read all the other table with unique key fields.

Hi Raj,

As mentiones u have data in 4 different internal tables and u want to display through 1 internal table, so declare ur it_final that should have all the fields to be displayed.

Now move the data from all 4 internal tables into this it_final using statement:

Move-Corresponding.

Say u have 4 internal tables it_tab1, it_tab2......

Loop At it_tab1 into wa_tab1.

Move-Corresponding wa_tab1 to wa_final.

Append wa_final to it_final.

EndLoop.

Loop at it_tab2 into wa_tab2

Move-corresponding wa_tab2 to wa_final

modify it_final from wa_final transporting fld1 fld2......

Endloop.

Here transportingwill contain the fields which are to be transfered frfom second internal table, so it will not affect the modifications from internal table1.

Hope it helps to resolve ur problem.

Please revert back for any clarification.

Regards,

Ashish

Hi,

If those internal tables have common key then u can merge all into on single that should contain all fields of 4 internal tables .

Otherwise you have one option in ALV to display all internal tables one by one .

Here is the sample program for Blocked ALV

report zvenkat_blocked_alv.
