Problem with DYNP_VALUES_READ - ME21N

Former Member — Fri, 25 Jun 2010 19:41:33 GMT

Hello Gurus,

I have this problem:

In transction ME21N and ME22N:

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 you help me?

Thanks

I want to read EBELP and INFNR.

Below is code that i'm using:

----

MOVE 'MEPO1211-EBELP' TO t_campos-fieldname.

APPEND t_campos.

MOVE 'MEPO1211-INFNR' TO t_campos-fieldname.

APPEND t_campos.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = 'SAPLMEGUI'

DYNUMB = '1211'

TABLES

DYNPFIELDS = t_campos

EXCEPTIONS

INVALID_ABAPWORKAREA = 1

INVALID_DYNPROFIELD = 2

INVALID_DYNPRONAME = 3

INVALID_DYNPRONUMMER = 4

INVALID_REQUEST = 5

NO_FIELDDESCRIPTION = 6

INVALID_PARAMETER = 7

UNDEFIND_ERROR = 8

DOUBLE_CONVERSION = 9

STEPL_NOT_FOUND = 10

OTHERS = 11.

READ TABLE t_campos INDEX 1.

l_ebelp = t_campos-fieldvalue.

READ TABLE t_campos INDEX 2.

l_infnr = t_campos-fieldvalue.

----

The sy-subrc = 0, but the FM didn't bring the values of the screen fields. Is there some wrong with the filed name?

Thanks.

Hello,

Where are you writing your code ?

This FM will read the values only if the screen is under processing. So if you can code in an enhancement.

I wrote at enhancement MM06E005 - FM EXIT_SAPMM06E_006.

In the exit EXIT_SAPMM06E_006, you can access the line item details using table TEKPO.

Hope this helps you.

Hi,

Your code

MOVE 'MEPO1211-EBELP' TO t_campos-fieldname.
APPEND t_campos.

MOVE 'MEPO1211-INFNR' TO t_campos-fieldname.
APPEND t_campos.

CALL FUNCTION 'DYNP_VALUES_READ'
EXPORTING
DYNAME = 'SAPLMEGUI'
DYNUMB = '1211'
TABLES
DYNPFIELDS = t_campos
EXCEPTIONS
INVALID_ABAPWORKAREA = 1
INVALID_DYNPROFIELD = 2
INVALID_DYNPRONAME = 3
INVALID_DYNPRONUMMER = 4
INVALID_REQUEST = 5
NO_FIELDDESCRIPTION = 6
INVALID_PARAMETER = 7
UNDEFIND_ERROR = 8
DOUBLE_CONVERSION = 9
STEPL_NOT_FOUND = 10
OTHERS = 11.

READ TABLE t_campos INDEX 1.
l_ebelp = t_campos-fieldvalue.

READ TABLE t_campos INDEX 2.
l_infnr = t_campos-fieldvalue.

Instead you can do this.

READ TABLE t_campos INDEX 1. -

Remove Index and replace with Fieldname condtion.

l_ebelp = t_campos-fieldvalue.

READ TABLE t_campos INDEX 2.----

Remove Index and replace with Fieldname condtion.

l_infnr = t_campos-fieldvalue.{

Read Table t_campus with key fieldname = 'MEPO1211-EBELP' .

Similarly do for the next screen field also.

If required debug the FM output and check the dynpro table.

hi rsely82 /all,

did you solve your problem?

Because i'm trying to get the value of KNTTP field from grid, just before press the SAVE buttom.. and i'm coding my request inside:

badi: CACL_CHARACTER_INPUT

method if_ex_cacl_character_input~set_character_input.

thank you so much for your help!

ps: one more answer: the table t_campos, what is the type for it? Or how is defined?
