Version: Windchill 12.1

 

Use Case: Using a DAO class that extends com.infoengine.connector.DataAccessObject to link 2 parts: public com.ptc.windchill.ws.GenericBusinessObject [] Link ( java.lang.String parentUfid, com.ptc.windchill.ws.GenericBusinessObject [] associations, java.lang.String [] propertyNames ) throws Exception { String [] ie$dao$names = { "parentUfid", "associations", "propertyNames", }; Object [] ie$dao$vals = { parentUfid, associations, propertyNames, }; Object ie$dao$ret = execute ( "Link", ie$dao$names, ie$dao$vals ); return (com.ptc.windchill.ws.GenericBusinessObject [])ie$dao$ret; }


Description:

Exception thrown when trying to create WTPartUsage between 2 parts.  Same call works in other WC installations (11, 12, 13, etc...) but failed in 12.1.2.  The settings are the same for all the WC servers tested.

This same request works in Windchill 10, 11, 12, 13.  It just does not work in Windchill 12.1.2.  I have checked the settings and they are the same in all the WC servers.  It appears that in 12.1.2, there is this validation check that does not allow this operation.

The error clearly state the quantity unit cannot be empty.

Are you specifying the quantity and the units?

If no, it look like doing so would fix this particular error.

I understand.  If I change my code to provide quantity and unit, it does work.  If this is how it should work, then will future versions behave the same way?  Again, this same code works in WC 10, 11, 12, AND 13.  Will there be a patch to fix this in WC 13 and any future versions of WC?

Again this is only an issue with Windchill 12.1.2.  Works for 10, 11, 12.1, 13.1.  I tried to create an issue, but it leads me to this community.  Is there a way to have someone from PTC/Windchill look at this?
