CALL DIALOG - Call a dialog module

&ABAP_BASIC_FORM4& CALL DIALOG dial.

Additions

1. ... AND SKIP FIRST SCREEN
2. ... EXPORTING f1 FROM g1 ... fn FROM gn
3. ... IMPORTING f1 TO g1 ... fn TO gn
4. ... USING itab ... MODE mode .

Effect

Calls the dialog module dial ; dial can be a literal or a variable.
To edit dialog modules, select Tools -> ABAP/4 Workbench -> Development -> Programming environ. -> Dialog modules .

Addition 1

... AND SKIP FIRST SCREEN

Effect

Processes the first screen of the dialog module in the background, if all required entry fields have been filled.

Addition 2

... EXPORTING f1 FROM g1 ... fn FROM gn

Effect

Specifies all data objects (fields, field strings, internal tables) to be passed to the dialog module. If the names in the calling and called programs are identical, you can omit " FROM g1 ". Otherwise, fi refers to the field in the dialog module, while gi specifies the field in the calling program.

Addition 3

... IMPORTING f1 TO g1 ... fn TO gn

Effect

Specifies all data objects (fields, field strings, internal tables) to be returned from the dialog module. If the names in the calling and called programs are identical, you can omit " TO g1 ". Otherwise, fi refers to the field in the dialog module, while gi specifies the field in the calling program.

Examples


DATA: BEGIN OF ITAB,
        LINE(72),
      END   OF ITAB,
      TITLE LIKE SY-TITLE.

CALL DIALOG 'RS_EDIT_TABLE'
    EXPORTING SOURCETAB FROM ITAB
              TITLE
    IMPORTING SOURCETAB TO   ITAB.

Notes

The system field SY-SUBRC is automatically exported and imported.

The unknown export/import data in the dialog module is ignored.

The data objects passed should have the same type or structure in the calling program and the dialog module.

Addition 4

... USING itab ... MODE mode

Effect

Calls the dialog module dial and also passes the internal table itab which contains one or more screens in batch input format.
If required, the dialog module may return a message to the system fields SY-MSGID , SY-MSGTY , SY-MSGNO , SY-MSGV1 , ..., SY-MSGV4 .
The specified processing mode mode mode can accept the following values:

'A' Display screen
'E' Display only if an error occurs
'N' No display

If the addition MODE is not specified, the processing mode is 'A' .

The return code value is set as follows:

SY-SUBRC = 0 The processing was successful.
SY-SUBRC <> 0 The dialog ended with an error.

Notes

All lock arguments are automatically exported and imported.
In contrast to a transaction, a dialog module does not form its own LUW (see Transaction processing ). Any update requests which occur there are not processed until the calling program executes a COMMIT WORK .

To return from the dialog module, use the key word LEAVE PROGRAM .

Note

Runtime errors

CALL_DIALOG_NOT_FOUND : The called dialog module is unknown.

CALL_DIALOG_WRONG_TDCT_MODE : The called dialopg module contains errors (incorrect entry in table TDCT ).

CALL_DIALOG_NAME_TOO_LONG : The name of a parameter is longer than permitted.

CALL_DIALOG_NO_CONTAINER : No memory for parameter transfer.
