Several important business object attributes have different standard lengths in Windchill and SAP (see Attribute Lengths table). Windchill ESI assumes that your business process limits the Windchill attributes to the lengths allowed by SAP. If the attributes sent are longer than allowed by SAP, BusinessWorks throws an exception. To enforce the length assumptions systematically, systems integrators/customizers can add validation programming logic to Windchill or modify SAP to extend the attribute lengths.

For more information on how to limit Attribute Lengths in Windchill, refer to the "Customizing Column Lengths" section of the Windchill Customization Guide (Windchill 自訂指南).
