Some fields are not appear in "Originals" Tab in DIR

Hi Experts,

In DIR some fields not appeared under the "Originals" tab like Document Status, Status Text, Created by User and Date/Time. I just wanted to know why it is not coming.

While seraching for information, i found that i had to installed ECL viewer then only possible to see these fields but ECL Viewer is allready installed & available with SAP GUI as i am able to see Autocad files in ECL Viewer.

I am not able to understand, did i am missing any configuration or it is just Bug in SAP DMS.

if anything needs to be done from configuration point of view, please provide me detail information.

thanks...
