Create Part Picker for New Attribute
I have created a new local (according to https://www.ptc.com/en/support/article/CS348371?source=search , the attribute cannot be global) attribute associated with a "WTDocument" sub-type. I intend on adding this new attribute to one of the layouts associated with the sub-type. I wish to configure the attribute in such a way so that, when a user wishes to populate the attribute value field, they have the ability to use a "Picker" to make a selection from the WTParts that exist in the instance. Specifically, I would want the part number to be inputted into the attribute field upon selection.
I have been looking at various articles/resources of PTCs and I can see that there is potentially a number of ways of doing this. My understanding is that a "Data Utility" could potentially provide the functionality I'm looking for.
Can anybody advise on the best way of achieving my requirement? If any files need to be updated on the server as part of any solutions, please could the full paths be stated? I have noticed that some of the paths referenced on the PTC sites are not featured as part of my server install.
