New to BCS hence needs guidance from you experts
1. Can we define Trading Partner for a specific Item in a company or replace the existing partner with new partner
2. I have uploaded a file thru Flexi upload method, I want to reload that file with some changes, will it remove the entire data loaded earlier thru this file. For example, if I hv uploaded 10 items earler now I need to upload only 8 items, will it remove/delete the remaining 2 items
3. What could be implications in doing re-upload, or do we need to chg some configuration.
Would be thankful on your inputs.
