Dynproproblems - How to reset input fields after exception?

Former Member — Mon, 10 May 2010 13:14:36 GMT

Hi @ all,

I have the Problem that after an exception & his error message all input fields (in my dynpro) are gray marked & can not be field again. Is there any function for reset the input fields, because i don't want to restart the transaction by the transactioncode.

Thaks a lot.

Regrads

Phil.

This is done by [FIELD and CHAIN statements|http://help.sap.com/saphelp_46c/helpdata/en/9f/dbaa4735c111d1829f0000e829fbfe/frameset.htm] in module pool program.

Hi Philipp,

You can use I-messages instead of E-messages (and of course refuse to do the action the user requested).

And Is there no easyer way to do this like call screen 0100 again or initial screen 0100?

Hi,

An E-Message in PAI will gray out all screen fields which are not in the FIELD or CHAIN module of the current PAI module (Marcin already mentioned that). Please refer to the documentation of those flow logic commands.

To prevent fields from being greyed out simple use:

message Ixxx with ....
leave screen.

Leave screen will leave PAI and start PBO of the next screen (which is probably the same screen again, check your screen attributes, if not use LEAVE TO SCREEN SY-DYNNR).

Philipp, as Marcin explained, you should use:


CHAIN.
  FIELD : <list of fields>.
    MODULE paimodule.
ENDCHAIN.

it means that any error message sent by paimodule will make the <list of fields> input-capable (and all the other ones will be protected). This is the basis of dynpro programming.
