We have custom webjcets for creation of WTpart and WTPartUsageLink.
These were able to use with no problem in Windchill 9.1.
But the webject for WTPartUsageLink only when it updates multiple records(ex: a process is a update of one parent and creations of multiple WTPartUsageLink) in one transaction, no longer returns the process after upgrade from 9.1 to 11.1.
The webject for WTpart (this process is always one record update in one transaction), and also webject for WTPartUsageLink when it updates one record in one transaction have no problem under Windchill 11.1.
We have thoroughly investigated this webject's logic and it seems fine. We also checked property files(wt.properties and db.properties), but could not determine whether they were affected or not.
Are there any other points we should investigate to help us resolve this issue?
