Check for mandatory attributes

[former_member728513]

Hi experts,

We need to make a few input fields on WDA "/SAPSRM/WDC_UI_DO_SHIPTO" mandatory. I've created an enahancement implementation and removed the standard fields we want to be required and re-created new fields based on the standard ones. I've set the "STATE" flag for each of the input fields to REQUIRED and implemented the code below:

  data: lo_wd_view_controller type ref to if_wd_view_controller.

  lo_wd_view_controller = wd_this->wd_get_api( ).

* Check for mandatory attribute
  cl_wd_dynamic_tool=>check_mandatory_attr_on_view(
  exporting view_controller  = lo_wd_view_controller
            display_messages = abap_true ).

The above code was implemented in the "WDDOBEFOREACTION" method. We tried it as a pre-exit, post-exit and overwrite method but none of them trigger a message of any sort if the input fields are not populated.

As a sanity check I created a quick bespoke WDA with a couple of input fields and implemented the above actions and everything worked great so I'm at a loss to what the issue could be within the enhancement implementation.

Any help or guidance would be very much appreciated.
Thanks in advance,
Chris

Hi,

Have you placed a breakpoint to make sure code is actually executed? There has been issues in some applications with pre-exit or post-exit not being executed but don't know if that could be the case here..
