Missing data when extracting data from Cerner and generating QVD files in QlikView
I have an issue with incremental loading in QlikView. The data is extracted from Cerner and saved in QVD files. This task is set to auto -run every four hours. We noticed that data was extracted on 4/1/2021 but didn't go into QVD file. It went back normal the next day. Does anyone have the similar issue?
I have another question. This QVD file is generated by incremental loading. How can I recover only data on 4/1/2021?
