Dynamic Validation Entities

Question

I have an FDM Location that a lot of companies will be loading through. Rather than setting up seperate locations / validation entities for each company, I was hoping to use an Event Script which changes the Validation Entity as the data is being processed.
Does anyone have the sample script for this?
Much Appreciated,
Mike

This code can be put on any method (including event handlers) since it doesn't need a reference to the view (thus not forcing you to use WDDOMODIFYVIEW), it sets the required flag based on the binded context attribute:
  DATA:
    lr_elem       TYPE REF TO if_wd_context_element.
  lr_elem = wd_context->path_get_element(
              path = wd_this->wdctx_header
  lr_elem->set_attribute_property(
      attribute_name = 'BNDDT'
      property       = lr_elem->e_property-required
      value          = iv_active_flag   "Boolean parameter i.e. TYPE WDY_BOOLEAN
So, in your event handler for the ONENTER action in your inputfield, you decide if the flag is set as true or false depending on the entered value.
Then you can call in WDDOBEFOREACTION the method cl_wd_dynamic_tool=>check_mandatory_attr_on_view to issue a message in case the field was not populated.
Hope this helps.
