Hi,
my report is failing with "ERROR: Empty path name is not legal" since yesterday. I did change the report but can not find the cause.
I already tried disabling dynamic naming and removing folder destination but no luck.
NP 18 (also after upgrade to 18SR1), QV 12.2SR1, ppt version 2010.
Anyone encountered this before?
rpc
Thanks,
Matus

It was a combination of incorrect column name in a table and incorrect filter.
That is why it failed in both cases - filter without objects and objects without filter.
After I fixed the filter it was still failing. At the end I had to update the tables (columns were removed + added). This fixed the problem and the report started working again.
Thanks a lot for your help!
