We have some flows that have been brought into openLCA via excel spreadsheet import. Some of these flows were imported as elementary flows (because they were marked as such in the spreadsheet) when they should be product or waste flows. Would it be a bad idea to change the tbl_flows.FLOW_TYPE from "ELEMENTARY_FLOW" to "PRODUCT_FLOW" or "WASTE_FLOW" by SQL commands or even manually updating with a tool like SQuirreL?
