different data with another structure in ALV

Former Member — Fri, 19 Feb 2010 09:49:52 GMT

Hello everyone,

I'm having trouble with my ALV grid.

In my functiongroup i have a screen, in the PAI of that screen i have 3 flagvariables to display 3 different types of data.

In my PBO i check those flags and display the desired data.

Now, in each if statement i have:

IF container IS INITIAL.

CREATE OBJECT container

EXPORTING

container_name = 'CONTROL_AREA'.

CREATE OBJECT grid

EXPORTING

i_parent = container.

get fieldcatalog

PERFORM create_workitem_fieldcatalog.

CALL METHOD grid->set_table_for_first_display

EXPORTING

i_default = 'X'

CHANGING

it_outtab = lt_wrkitm

it_fieldcatalog = lt_fieldcat

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4.

IF sy-subrc <> 0.

ENDIF.

ELSE.

CALL METHOD grid->refresh_table_display.

ENDIF.

Now, my question is: is it possible to change the data and fieldcatalog in the alv during runtime.

I have twice the same structure, so that ain't the problem. But the third one has another structure and another fieldcatalog.

When i run the program, all the code works fine, but the output is still the initial one.

I tried to FREE container and grid and create a new alv to display the third option, still no luck.

I will give another overview of the problem.

Situation A: (1 and 2 has the same structure)

Option 1

option 2

option 3

chosing 1: display correct data

chosing 2: display correct data

chosing 3: display data of option 2

chosing 1:display correct data

Situation B: : (1 and 2 has the same structure)

Option 1

option 2

option 3

chosing 3: display correct data

chosing 2: display data of option 3

chosing 1: display data of option 3.

Hope you understand my problem and you're able to help me.

Greetings

Merijn.

Hi,

i think we need ot create the field catalog also dynamically depending on the selections.

thanks,

Well, I found the solution...

I just didn't use the grid->refresh_table_display.

So i created the container and the grid object once and just used the set_table_for_first_display whenever i wanted to display the alv.

Hopefully my solution can help others.

Thanks anyway Teja
