If the following error message appears when trying to modify a Step in a Test Case:
Failed to post DESSTEPS values
This is because Oracle introduced a bug in 220.127.116.11. The bug limits schema length to 29 characters but QC limits it to 30.
The solution to this problem is to install the following Oracle patch:
Patch 11822454: DRG-10607 “INDEX META DATA IS NOT READY YET FOR QUEUING DML” SINCE 18.104.22.168 UPGR
A workaround is to copy the project to a new project with a schema name no longer than 29 characters.
