Environment

Release : 10.4.1

Component : Spectrum Core / SpectroSERVER

Cause

Spectrum was checking for deleted models during Full Sync, this should not happen and those models should be ignored until the next incremental sync is performed.

Resolution

Code changes were made in Spectrum to prevent this.
Please open a support issue and request patch 10.04.01.PTF_10.4.120a from Support.
This problem was also seen in 10.3.2 and the patch to resolve is Spectrum_10.03.02.D90e

If you have installed 10.3.2_BMP_10.3.202 then you will need patch 10.3.2_PTF_10.3.257

Additional Information

Please note that Spectrum_10.04.01.PTF_10.4.120a  requires Spectrum_10.04.01.BMP_10.4.101b to be installed first.  Spectrum_10.04.01.BMP_10.4.101b  is required on all servers (OneClick and SpectroSERVER) in the environment.
