DOCUMENTATION

Functionality

You can use this function module to reset selected help processor field contents in the corresponding screen fields

Example

  • data: dyname like d020s-prog value 'TESTPROG',

  • dynumb like d020-dnum value '100'.

  • data: begin of dynpfields occurs 3.

  • include structure dynpread.

  • data: end of dynpfields.

  • move 'TABNAME' to dynpfields-fieldname.

  • move 'Testtable' to dynpfields-fieldvalue.

  • append dynpfields.

  • move 'FIELDNAME' to dynpfields-fieldname.

  • move 'Testfield' to dynpfields-fieldvalue.

  • append dynpfields.

  • call function 'DYNP_VALUES_UPDATE'

  • exporting

  • dyname = dyname

  • dynumb = dynumb

  • tables

  • dynpfields = dynpfields

  • exceptions

  • invalid_abapworkarea = 01

  • invalid_dynprofield = 02

  • invalid_dynproname = 03

  • invalid_dynpronummer = 04

  • invalid_request = 05

  • no_fielddescription = 06

  • undefind_error = 07.


    • Notes
    This function module should be used in the user-programmed help if one or more screen fields are to be given selected values, e.g. if the values are to be reset after calling HELP_VALUES_GET_WITH_TABLE_EXT. automatic value reset, as performed e.g. by the function module HELP_VALUES_GET_EXTEND, can also be overwritten.
    Screen field contents are read by the function module DYNP_VALUES_READ.
    The field names in DYNPFIELDS can be defined by the user, as in the above example,where the fields TABNAME and FIELDNAME occur on the screen. A Dictionary reference of these fields (... like...) is unaffected.
    The module DYNP_GET_STEPL must first be called in strp-loop or table control to set the correct step-loop.
    All exceptions are called by the system function HELP_GET_FIELDS.

    Parameter documentation

  • Import parameters:

  • DYNAME: Program name (of the calling screen)
    • Meaning:   Name of the program from which the function

the step-loop lines, if it is a
step-loop screen.
