FWPMUPD (8.4.c) This process updates the MWESB vendor type identifiers (MN, SB and WB) in the Banner vendor records based on record matches with the GAO file. The GAO file is located in the OSBA Banner instance and is a subset of the larger MWESB vendor file maintained by the GAO. The subset file contains the minimum data needed to identify a Banner vendor as MWESB. The OSBA file is updated from the larger MWESB vendor file the last working day of each month.
