The grid includes a column for each segment that your agency uses. For each segment, click the popup button and select the code from the list.
Note: If you plan to use the MyGLAccountMaster BOD (Core\Messaging\Mappings\Import\Resources\SyncGLAccountMasterImport.xml in the Operations and Regulations application folder) to import budget numbers, the budget numbers that you define in Operations and Regulations can only have one segment. Budget numbers that are imported through this BOD are always placed in the SEGMENT1 column of the BUDGETNUMBER table, so your Operations and Regulations budget numbers must be set up to match.
