We are re-implementing our SAP B1 system and are migrating data from the old system to the new. I am relatively new to SAP B1 and would like some guidence on what is the best order to import the files. For example, you can not have a preferred vendor on an item unless the vendor exists, so you need to upload business partners before items. You can not have a contact person on the BP unless you have uploaded those, etc. These are the kind of dependencies I am looking for. What is the best order to proceed in?
