update dynpro field

[Former Member]

Hi,

I am currently adding some dates validations on an user exit. When I validate a date, I call a pop-up window to tell the user the date is wrong and I also suggest a new one. My problem is that I can´t update the field in the dynpro with the new value for the date afther the user accepted to change the date with the one I suggested.

Is there anyone who can help me with this?

Thanks in advance,

Best Regards,

Hi Martin,

It seems to me that you have given an error message when the value entered by the user has been found to be incorrect. In programming a Screen in ABAP, the error message ashould always be given in the FIELD MODULE.

For example, if the data field that you have on your screen is lv_datum, then your flow logic should have something like -

PROCESS AFTER INPUT.
  FIELD lv_datum MODULE validate_date.

Now, if ou give an error message in the <b>validate_date</b> module, then you will see that the data field is open for inout even after the error.

Do get back if I have not correctly assessed the problem.

Hi, for reading the user inputted in the dynpro screen, call this function

TMP_FLD-FIELDNAME = 'XXXX'. * field name on dynpro

APPEND TMP_FLD TO IT_FLD.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = SY-REPID

DYNUMB = SY-DYNNR

DETERMINE_LOOP_INDEX = CNS_X

TABLES

DYNPFIELDS = IT_FLD

EXCEPTIONS

OTHERS = 01.

Hope it will be helpful
