Linked Object in Edit Control Master Data

Hi All,

I have a requirement to enhance Linked Object drop down in 'Edit Control Master data' transaction.

By adding a new value to the list, the corresponding input field should be visible dynamically.

I was able to add the new value to the dropdown list and create new input field .

But I am unable to make to input field appear dynamically when ever the selection is made in the dropdown list.

The Component Configuration- EHFND_UI_CTRL_REF_FRM. Any inputs would be greatly appreciated?
