As you may be aware, as well as my work here on the ONE.Source Community, I also do quite a bit of consulting with SAP Business One users and I also run an SAP Business One Cloud Hosting company - SMB Cloud Services.
In the course of doing the various tasks involved in keeping the HANA Servers up and optimised I often have to go digging for information on the SAP Support Portal - sometimes a challenge in itself although it has continued to improve!
When I find useful documents I will share them with you and here's one I found when working on some data exports and imports that has a summary of some guidance that you may find useful
I have posted the link to the SAP Note here
If you don't have access to the SAP Support Portal (which as an SAP Business One customer you should have) I also grabbed the latest update of the note in to a PDF and you can find it attached here
