QlikView Expressor v3.11.1 (r26528)
Qlik is aware of issues related to the QVD feature that was added to the Read and Write QlikView operators in v3.11.1 (refer to the list below for details on each issue). Qlik R&D has identified the root causes of each of these issues and is in the process of verifying their respective fixes for the upcoming v3.12 release of QlikView Expressor.
Due to the variability of their occurrence and lack of available workarounds, Qlik Product Management advises users of QlikView Expressor v3.11.1 to avoid using the QVD mode of the Read and Write QlikView operators in any dataflows used in a production environment. Note that this advice does not apply to the use of the QVX mode to read and write .QVX files using the Read and Write QlikView operators which remains stable in v3.11.1.
