How to make dynamic WD filed as Read Only

Hi All,

We are working on SLM /SRM  module and below is our requirement  .

        We  are adding several fields (Attributes)   to SAP standard Classification Class  in CT04 and CT02  transactions. After this we are able to see those fields in the screen also ,but in the    EDITABLE  mode ,but our customer needs in Read Only mode, where we will fill the data during run time.

  SAP using FPM_OVP_Component and when I checked the WD  Component its shows Empty View:) . So SAP populating all the fields at runtime .Using feeder class  .

      But in the class I am not able to find any method which can help me to make this fields as Read Only . Do any one of you guys have the idea on this. If so let me know.

Thanks and Regards
