selection screen field value

[Former Member]

Hi All,

I am facing a problem with selection screen parameter.

I have one file parameter p_fname TYPE rlgrap-filename OBLIGATORY.When I enter some file path and excute I will get the result and once again when I start to execute the program I expect the previous value(file path) should be available for this file parameter that has entered on the selection screen but I am not getting that.

I dont find any parameter id for this field data element.

Please let me know how to do this?

Best Regards

Ramesh

Hi,

You should have..

DATA: FLNAME TYPE STRING.

PARAMETERS: FILENAME TYPE RLGRAP-FILENAME.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILENAME.

CALL FUNCTION 'F4_FILENAME'

IMPORTING

FILE_NAME = FILENAME.

Find the demo code below, it uses the file :

report ZDS_BDC_MM01_2
       no standard page heading line-size 255.

*include bdcrecx1.

*parameters: dataset(132) lower case.
***    DO NOT CHANGE - the generated data section - DO NOT CHANGE    ***
*
*   If it is nessesary to change the data section use the rules:
*   1.) Each definition of a field exists of two lines
*   2.) The first line shows exactly the comment
*       '* data element: ' followed with the data element
*       which describes the field.
*       If you don't have a data element use the
*       comment without a data element name
*   3.) The second line shows the fieldname of the
*       structure, the fieldname must consist of
*       a fieldname and optional the character '_' and
*       three numbers and the field length in brackets
*   4.) Each field must be type C.
*

hi use this ,

PARAMETER P_FILE LIKE IBIPPARMS-PATH.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_FILE.

CALL FUNCTION 'F4_FILENAME'

EXPORTING

PROGRAM_NAME = SYST-CPROG

DYNPRO_NUMBER = SYST-DYNNR

FIELD_NAME = 'P_FILE'

IMPORTING

FILE_NAME = P_FILE.

Hi,

Check this piece of code.

DATA: v_var TYPE rlgrap-filename.
SELECTION-SCREEN: BEGIN OF BLOCK b1.
PARAMETERS:p_fname TYPE rlgrap-filename DEFAULT v_var OBLIGATORY.
SELECTION-SCREEN: END OF BLOCK b1.

v_var = p_fname.

Reward points if it helps.

Regards.

Abhisek.
