Newbie here again. 15 Enterprise in the cloud for now. Small startup company, small number of skus (<20), mostly ingredients for  a food product plus some packaging. Have about 6 months of inventory transaction history. Want to import old data from .xlsx since it will has lot traceability data that I must maintain into the future so don't want to just use a starting inventory quantity. So far, any attempt to save an inventory transaction in the past is futile. Not sure about import as there is no documentation on this that I have found. If this is not possible then I am wasting my time with this software and need to cancel.
