Unable to create subtype for EPM Document

[taruchamy]

wt.epm.EPMDocument cannot have more than one type

This is a new installation of 10.2 M030, where creating sub type for EPM Document failed.

But sub type for the Part is successfully created.

Below is the error message :

Caused by: wt.util.WTException: wt.epm.EPMDocument cannot have more than one type.

Nested exception is: (wt.epm.util.EPMResource/132) wt.util.WTException: wt.epm.EPMDocument cannot have more than one type.

Thanikachalamurthi Aruchamy‌,

This might be stating the obvious, but did you check the setting "Subtypeable" in Type/Attribute Manager?

Hi Ben,

Thanks.

I did not check “SubTypeable” earlier. Howevwe, after enabling the same, the issue still persists.

Hi Thanikachalamurthi,

This is intended behavior. Even I tried it with subtypable to true on older releases (10.0 and 10.1) and got same behavior.

EPMDocument cannot be subtyped and "wt.epm.EPMDocument cannot have more than one type" error message is expected while creating of Soft-Type for EPMDocument in Type and Attribute Manager.

Regards,

Shirish
