Hi,

DSYS_SHOW_FOR_F1HELP

AT SELECTION-SCREEN ON HELP-REQUEST FOR <MY FIELD> .

PERFORM HELP_F1.

In the routine you have to insert the code to display the text, it depends on how you want to create it.

For example I created a text by trx SO72 and this is the code to display it:

DATA: T_LINE LIKE TLINE OCCURS 0,

XHEAD LIKE THEAD,

HELP_INFO LIKE HELP_INFO,

TEXC LIKE SY-UCOMM OCCURS 0,

V_OBJECT LIKE DOKHL-OBJECT.

DATA: PREF_SIMG(4) VALUE 'SIMG',

DOCID_HY LIKE DOKHL-ID VALUE 'HY'.

CONCATENATE PREF_SIMG 'Z_MY_DOC' INTO V_OBJECT.

Estrazione testo

CALL FUNCTION 'DOCU_GET_FOR_F1HELP'

EXPORTING

ID = DOCID_HY

LANGU = SY-LANGU

OBJECT = V_OBJECT

IMPORTING

HEAD = XHEAD

TABLES

LINE = T_LINE

EXCEPTIONS

RET_CODE = 1

OTHERS = 2.

CASE SY-SUBRC .

WHEN 0.

GET CURSOR FIELD HELP_INFO-DYNPROFLD.

HELP_INFO-DOCUID = DOCID_HY.

HELP_INFO-DOCUOBJECT = V_OBJECT.

HELP_INFO-SPRAS = SY-LANGU.

HELP_INFO-PROGRAM = SY-REPID.

HELP_INFO-DYNPRO = SY-DYNNR.

HELP_INFO-DYNPPROG = SY-REPID.

HELP_INFO-PFKEY = SY-PFKEY.

HELP_INFO-FIELDNAME = HELP_INFO-DYNPROFLD.

CALL FUNCTION 'HELP_DOCULINES_SHOW'

EXPORTING

HELP_INFOS = HELP_INFO

OVERLAY_HEADER = XHEAD

TABLES

EXCLUDEFUN = TEXC

HELPLINES = T_LINE.

WHEN OTHERS. MESSAGE S720(SH).

ENDCASE.
