API to link non latest EPM Document to WTPart using EPMBuildRule

Are you trying to do this via a code customization or manually from a workspace? Curious as to why you would want to do this?

Could you describe a little more what the end goal is?

I recently looked into something that may be related. If you have:

• CAD document 1 rev A with Owner link to WTPart 1
• CAD document 1 rev B with Owner link to WTPart 2

Every time you do a build of a CAD assembly using that CAD document, the resulting WTPart structure will use WTPart 2.

I'm not sure what your end goal is, but setting the links may not be enough. I think the Build action itself uses the latest version of the CAD.

I could use some more context here, and note as @HelesicPetr  states below, the EPMBuildRule link is actually between versions, not between iterations (take a look at the database table - the values are BRANCHIDA3A5 and BRANCHIDA3B5 which point to BRANCHIDITERATIONINFO).

That said, a code fragment to create one is below -- this does not run a build or anything else, it just creates the link.

WTPart workingPart = (WTPart)WorkInProgressHelper.service.checkout(wtPart, WorkInProgressHelper.service.getCheckoutFolder(), "").getWorkingCopy();
EPMBuildRule epmBuildRule = EPMBuildRule.newEPMBuildRule(epmDocument, workingPart, CADHelper.OWNERLINK);
PersistenceHelper.manager.store(epmBuildRule);
WorkInProgressHelper.service.checkin(workingPart, "Link with CAD");
