Country specific checks, need standard settings information
I am trying to work on setting up vendors in SAP with international bank information for payments by wires. I am having trouble with the information that is provided to coordinate with how SAP is set up. I have banking information from different countries, however when i try to enter in the data, i keep getting error messages like bank key needs to be numberic. I looked at the country specific checks, and i keep going on line and everyone tells me not to really change the settings that SAP has provided. I need help, specifically right now i have a switzlerland bank, with a BIC that is both Alpha and numeric, however when i put that info in the bank key, SAP states it can only be numeric. Now i know i can change the settings, but again like i said, i have seen other sites tell people not to.
Any help would be greatly appreciated.
PS, for the CH - swizterland bank, i went on their site and their BIC number is both numberic and alpha, so i guess i ask the next question, is that BIC information really needed to be put in the Bank key field?
