If the date is wrong in business objects, check the date style specified in the connector's RDBMS.initsession configuration property. The date format must correspond to the date format used in maps for the business objects.
WebSphere Business Integration Adapter native maps assume that the NT short date style is MM/dd/yyyy. If the short date style is any other format, change the map rules to reflect the new date format and recompile the maps. Use the RDBMS.initsession configuration property to issue SQL statements that set the date format in the database.
