我正在将 Crystal 报表转换为 SSRS 报表。 需要用多个 arguments 转换一个 IIF 表达式

Question

I need to convert an expression with multiple arguments. Below is the crystal expression

if Sum ({t_bol_cartons.no_of_cartons}, {t_bol_cartons.hu_id}) = 0 and {t_bol_cartons.sub_status} <> 'S' and {t_bol_cartons.loaded} <> 0 then 1 else if Sum ({t_bol_cartons.no_of_cartons}, {t_bol_cartons.hu_id}) = 0 and {t_bol_cartons.loaded} = 0 then 0 ELSE Sum ({t_bol_cartons.no_of_cartons}, {t_bol_cartons.hu_id})

I have converted in SSRS as below

IIf((Fields,no_of_cartons + Value.Fields.hu_id.Value = 0) AND (Fields,sub_status,Value <> "S") AND (Fields.loaded.Value <> 0)."1", IIf((Fields,no_of_cartons.Value + Fields.hu_id.Value = 0) AND (Fields!loaded.Value = 0),"0", (Fields!no_of_cartons.Value + Fields!hu_id.Value)))

I am getting an error as "The Value expression for the textrun 'Sum_cont.Paragraphs[0].TextRuns[0]' contains an error: [BC30516] Overload resolution failed because no accessible 'IIf' accepts this number of arguments." Please could anyone help with this? Thank you.

The is first part is wrong, you have Fields!no_of_cartons + Value instead of Fields.no_of_cartons.Value

Try

IIf(
  (Fields!no_of_cartons.Value + Fields!hu_id.Value = 0) AND (Fields!sub_status.Value <> "S") AND (Fields!loaded.Value <> 0),
  "1", 
  IIf(
      (Fields!no_of_cartons.Value + Fields!hu_id.Value = 0) AND (Fields!loaded.Value = 0),
      "0",
      (Fields!no_of_cartons.Value + Fields!hu_id.Value)
      )
    )
