Problem with DYNP_VALUES_READ

Former Member — Fri, 04 Dec 2009 11:14:09 GMT

Hallo Gurus,

I have this problem:

in transaction ME21N I have linked a custom Search help on field "Outline agreement" (on PO position).

To develop search help I have used a "search help exit" using a custom function.

In this function I have used function DYNP_VALUES_READ to read the fields that user has filled on the main screen of Purchase order, but the function does not give any result (table empty...).

I have used both SAPLMEGUI 1211

and SAPLMEGUI 0014

as program / dynpro in the function interface.

Could I trouble you for a help...?

Thank you very much!!!

data : dynpread type standard table of dynpread with header line.
* You need to pass fieldname to the Dynpread-fieldname.

CALL FUNCTION 'DYNP_VALUES_READ'
  EXPORTING
    dyname                               = dyname
    dynumb                               = dynumb
  TABLES
    dynpfields                           = dynpfields  " You need to pass this one
 EXCEPTIONS                                             " All exceptions should uncommented
   INVALID_ABAPWORKAREA                 = 1
   INVALID_DYNPROFIELD                  = 2
   INVALID_DYNPRONAME                   = 3
   INVALID_DYNPRONUMMER                 = 4

   INVALID_PARAMETER                    = 7
   UNDEFIND_ERROR                       = 8
   DOUBLE_CONVERSION                    = 9
   STEPL_NOT_FOUND                      = 10
   OTHERS                               = 11

if sy-subrc is initial.
read table dynpread with key fieldname = 'YOUR_FIELD_NAME'
endif

Cheerz

Hallo Ram,

thanks for your kind answer.

Actually the instruction "tables ******" and the exceptions were already uncommented.

Try the following code i hope this will resolve your concern

TABLES:dd03l.
DATA : BEGIN OF ptab OCCURS 0,
field LIKE dd03l-fieldname,
END OF ptab.
DATA : BEGIN OF dynpfields OCCURS 0.
        INCLUDE STRUCTURE dynpread.
DATA : END OF dynpfields.
DATA: it_ret TYPE STANDARD TABLE OF ddshretval,
        wa_ret TYPE ddshretval.
data: read_table TYPE char7.
SELECTION-SCREEN : BEGIN OF BLOCK block1 WITH FRAME TITLE text-001.
PARAMETERS : p_table TYPE dd03l-tabname OBLIGATORY. "Table name
SELECTION-SCREEN : END OF BLOCK block1.

SELECTION-SCREEN : BEGIN OF BLOCK block2 WITH FRAME TITLE text-002.
SELECT-OPTIONS: s_field FOR dd03l-fieldname NO INTERVALS OBLIGATORY.
SELECTION-SCREEN : END OF BLOCK block2.
