Error while executing Query with Variable.

Question

Hi All,
I have written a query to fetch values from some user tables and sap tables. The query is as below.
select a.docentry,a.u_scname,e.block,e.[City],
e.[Country], e.[State1],
e.[StreetNo], e.[ZipCode],
e.[Building], e.[Cellular],a.[U_WONo], a.[U_DocDate],
a.[UserSign], b.[LineId], b.[U_Des],
b.[u_SDes], b.[U_UoM],
b.[U_Qty], b.[U_Rte],
b.[U_Tamt], a.[U_PrjName], a.[u_WO_PB],
a.[U_WO_UL], a.[U_WO_FC],
a.[U_WO_PYT], a.[U_WO_COP],
a.[U_WO_TRMT], a.[U_WO_DocSub],
a.[U_WO_ADV], a.[U_WO_OCondition],
a.[U_WO_PRPBY], a.[U_WO_RCMBY],e.[CntctPrsn],
(T4.[WhsName]+ '-' + T4.[Street] +'-' + T4.[Block])  as 'Work Address ',
T4.[Building], T4.[City],
T4.[ZipCode], T4.[U_PMCNT],  T4.[WhsName], e.Taxid0
from [@e360_owor] as a join [@e360_wor1] as b
on a.docentry = b.docentry
left outer join
( select c.cardname,d.TaxId0,d.Taxid1, c.block, c.[City],
c.[Country], c.[State1],
c.[StreetNo], c.[ZipCode],
c.[Building], c.[Cellular], c.[CntctPrsn]  from ocrd
as c  join crd7 as d  on  c.cardcode = d.cardcode 
  where d.TaxId0 is not <b>null</b> ) as e
on
a.U_SCName = e.CardName 
left outer join OWHS T4 on T4.[WhsName] = a.[U_Prj]
where
a.U_WONo = '[%0]'
In this code, when the variable is assigned to field U_WONo, then I get an error
Must Specify A Table To Select From. Statement 'Service Contractors' (OCTR) (s)  could nto be prepared.
But when the values for variables are hard coded, the query executes.
I have been working on it from long time, but same error exists. Could anybody help resolve the same...
I am using SAP B1 2007 B, patch level 15.
Thanks in advance,
Regards
Rohan

Answer 1

The error messages may be misleading. With complicated queries with parameter request I frequently saw references to service contract (or something other).
Sometimes SBO does not manage correctly variables in complicated queries and there is a note about the workaround to solve the problem:[Note730960|https://websmp130.sap-ag.de/sap/bc/bsp/spn/sapnotes/index2.htm?numm=730960]
