Custom Attribute on Document "References Documents" link

Hi all,

Using Windchill PDMLink 10.2.

I have, in the past added custom attributes for EPMDocument usage links directly in the Type and Attribute Management , navigating to the EPMDDocument .

Also, custom attributes in Part Usage link.

But, here I want to add custom attribute in the link "References Document", however there is no Object Type like this (Similar to EPmDocument Usage Link or Part Usage Link).

There is only Document Uses link, but this is meant for the Document Structure Tab and not for the References Document in the Related Objects tab.

If there is no object type for this link, then only way is to study what is going into that link through the JCA debug or look at the Document tables in DB..

Is ther any way out?

Thanks & Regards

Hari
