matnr TYPE vbap-matnr,

arktx TYPE vbap-arktx,

END OF help_item.

DATA: dynfields TYPE TABLE OF dynpread WITH HEADER LINE.

dynfields-fieldname = 'P_VBELN'.

APPEND dynfields.

**Read the Values of the SCREEN FIELDs

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

dynumb = sy-dynnr

translate_to_upper = 'X'

TABLES

hi,

you can directly attach f4 help to any field you want on selection screen.

select-option: s_matnr for mara-matnr matchcode object searchhelpname.

this way you can assign any help here.
