Filling in the selection screen parameters based on condition

[Former Member]

Hello,

I am trying to fill in default values for a parameter that is seen on the selection screen. This parameter refers to an O/P file name and needs to be filled with a default value based on the system that is being used:

For e.g: If the system ID is DV2, then the O/P file name should be
DV2\File A

if it is QA2, then the O/P file name should be
QA2\File A

I tried using IF...ELSE...ENDIF to check for sy-sysid :

IF sy-sysid = 'DV2'.

parameter: fname default '
DV2\File A'.

ELSE.

parameter: fname default '
QA2\File A'.

ENDIF.

but it gives the error "Parameter 'FNAME' has already been defined".

Is this possible? If yes, could someone please tell me how to do it?

Thanks,

what you need to do is to define your parameter once, then in the initialization event write the code to set the default for your values

so your code would be

parameters: fname like xxx.

initialization.

IF sy-sysid = 'DV2'.
 fname = '\\DV2\File A'.
ELSE.
 fname = '\\QA2\File A'.
ENDIF.

Thanks for your reply. However, if I use this IF..ENDIF condition in the initialization section, then it would not appear in the selection screen. Is it possible to determine this before the selection-screen is displayed.

Thanks,

using initialization will make it appear on the selection screen .so no issues for you. Try it and see

and if your file name differs just by the SID of the SAP box, then it is better to define a logical file name as Rob mentioned and use that instead of doing such hardcoding .

try to use

at selection-screen output ....(pbo event)

Unfortunately, it is not working...

Please find my code below and let me know if this is correct:

SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-183.

PARAMETERS: p_ifile LIKE rlgrap-filename OBLIGATORY "Input File

• DEFAULT 'F:\shared\acct\pr\sapje2000\pr_xxxje.prn', "01/06/03 Miu chg

DEFAULT 'F:\Accounting\payroll\pr\sapje2003\pr_xxxx_je.prn'.

PARAMETERS: outfile(40) LOWER CASE OBLIGATORY.

*********************************

SELECTION-SCREEN END OF BLOCK b1.

SELECTION-SCREEN SKIP.

SELECTION-SCREEN SKIP.

SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME TITLE text-020.

SELECTION-SCREEN END OF BLOCK b2.

outfile = '

ELSEIF sy-sysid = 'PR2'.

outfile = '

ENDIF.

Please tell me how I can use a logical filename.

Thanks,

where is your initialization command ? I see it is commented in your code

[Former Member]

try txn code FILE and see the option there.

else use

Initialization.

concatenate  '\\dbsapdv2\basis\flat_files\' sy-sysid '\payroll'  into outfile.
condense outfile no spaces.

there is no need to code for each system.

Thank you MxG, the event INITIALIZATION was missing. Thank you for correcting it.

Thanks to everyone for your useful input.

Please see the documentation under IMG activity:

System Administration -> Cross Client Maintenance of File Names and Paths

This way you don't have to worry about which instance you are on. The logical file name takes care of it for you.

I think you can use logical file names for this as well.
