Другим менее изящным способом было бы вложить ваши заявления IIF
=IIf(Fields!t_cpcp.Value ="310", "Purchased Material & Raw Material",IIf(Fields!t_cpcp.Value ="320", "Manufacturing Direct Labor",IIf(Fields!t_cpcp.Value ="325", "Subcontract Cost",IIf(Fields!t_cpcp.Value ="330", "Engineering Direct Labor",IIf(Fields!t_cpcp.Value ="340", "Manufacturing Labor O/H",IIf(Fields!t_cpcp.Value ="345", "Engineering Labor O/H",IIf(Fields!t_cpcp.Value ="350", "Material O/H",IIf(Fields!t_cpcp.Value ="355", "Labor O/H Surcharge",IIf(Fields!t_cpcp.Value ="360", "Subcontract Material Burden",IIf(Fields!t_cpcp.Value ="MFD", "Manufactured Items", Nothing))))))))))
Вы также можете сделать свою логику в запросе:
CASE t_cpcp WHEN '310' THEN 'Purchased Material & Raw Material'
WHEN '320' THEN 'Manufacturing Direct Labor'
WHEN ... THEN ....
ELSE ''
END as t_cpcp_DESC
