Administrators and users whom you awarded the corresponding rights are able to see and manage all imports done. The summary illustrates for which products data has been imported and from how many regions. At that point you can see immediately if data is missing for a product (empty fields in the original data file) or sales figures are set to zero.
The appropriate extensions will allow your Pharmalyzer for additional imports and data input at this point, for instance to add ex-factory figures to all imported data sets. Besides you decide whether an import should be visible in the views or not. And the deletion of an import happens as quickly as adding a new one.
