Dynamically show key fields of table on selection screen

[former_member690993]

Hi Experts!

My aim is to dynamically display the key fields of the table in a selection screen after entering a table name.

The mandate should not be shown.

Here are two examples:

Here all the three key fields (carrid, connid & date) of table sflight should be displayed.

At VBAK it only would be one key field (vbeln).

Does anyone has any idea on how i could implement this?

Thanks!

Ok, if you absolutely no idea why on earth you would have such a requirement, but I'll try and think along.

If the list of tables for which your program needs to work is known, and limited, I would create a dropdown for the table and separate selection blocks per table. That way you can show/hide those blocks depending on what table is chosen.

If this somehow has to work for all tables, then you have the option to generate a new report at runtime using the statement below.

INSERT REPORT <prog> FROM <program_table>.

For documentation see here: abapdocu

If neither option is to your liking, I'd suggest you take a look at how a transaction like SE16n works. That way you don't have to reinvent the wheel, but it'll require some debugging of standard code..

Also, I found that you can create parameters dynamically according to the abap docu, but the same isn't mentionned for select-options.

Hello Marlon,

You may try to use the Function modules FREE_SELECTIONS_INIT and FREE_SELECTIONS_DIALOG for this purpose.

Hope that helps.

Thanks,

Hello lbldraw427

It's not possible to have the selection screen created dynamically. You either have to have a predefined set of parameters like pvnierop suggests, or use a function like ahana.sengupta suggests.

To have the selection screen dynamic you need to regenerate it every time a user selects a different table. This is also how SE16 works - it regenerates the program every time different selection criteria fields are selected.

Kind regards,

Mateusz
