set_objkeya only works on ENTER

Hi,

I am calling NEW ACTIVITY from Lead. I have created custom button for this. I am not using create followup functionality.

In the do_prepare_output method of ZL_BT126H_C_SCDETAILS_IMPL (Activity). I am writting the following code.

      me->typed_context->btdocflow->set_objkeya( attribute_path = 'OBJKEYA'                                                          value = lv_value1 ).

But somehow its not working in the first round when the view is displayed. I need to press ENTER and then it works. Any idea how to fix it?

I have checked lv_value1 does contain the data in the first round also.

Thanks,
