Referencing UDF's with field values for approvals

Question

Hi there,
Apologies for the weird output I'm getting here - the forum engine is trying to markup my syntax. eg. of what it should look like " $[$38.11.0]"
I have created a generic approval template (due to sheer number of approvals required) for use with Marketing documents in SAP B1.
To explain what I'm on about - I'm not sure exactly what we call these fields in SAP B1, but as an example, the quantity field on the lines of a marketing document is $[$38.11.0]. This enables you to create a generic template across all marketing docs.
I have a UDF on the header which I need to reference in this approval query, but I need a generic reference to it. At the moment, the only way I can get it to work is to directly reference the table of the actual document e.g. $[ORDR.U_APPROVAL.0]. This makes it impossible to make the template generic.
I tried the following code, but I got an internal error 1004:
DECLARE @PROCEED VARCHAR(10)
SET @PROCEED = case when (SELECT ISNULL($[ordr.U_APPROVAL.1],'N')) = 'Y' then 'Y'
               case when (SELECT ISNULL($[oinv.U_APPROVAL.1],'N')) = 'Y' then 'Y'
               case when (SELECT ISNULL($[oign.U_APPROVAL.1],'N')) = 'Y' then 'Y'
               case when (SELECT ISNULL($[oige.U_APPROVAL.1],'N')) = 'Y' then 'Y'
               case when (SELECT ISNULL($[orin.U_APPROVAL.1],'N')) = 'Y' then 'Y' end
Select Result from (select case when isnull($[$38.30.0],'')='210' and @PROCEED = 'Y' then 'TRUE' else '' end as Result
union
select case when isnull($[$13.10001004.0],'')='210' and @PROCEED = 'Y' then 'TRUE' else '' end as Result) as T1 where result <> '' order by 1 DESC
If this worked, it would solve my problem, however, I don't think SAP likes referencing variables that are not on the current open form.
Is there some other way of doing this? SAP gurus out there - please come to my rescue!

Hi Suda,
I'm unfortunately still getting internal error 1004 with the following code:
DECLARE @PROCEED VARCHAR(10)
DECLARE @OBJECT NUMERIC(19,6)
SET @OBJECT = (SELECT ObjectCode FROM  NNM1 WHERE Series = $[$88.0.Number])
SET @PROCEED = (select case when @OBJECT = 17 THEN (SELECT $[ordr.U_APPROVAL.1])
               when @OBJECT = 13 THEN (SELECT $[oinv.U_APPROVAL.1]) 
               when @OBJECT = 59 THEN (SELECT $[oign.U_APPROVAL.1]) 
               when @OBJECT = 60 THEN (SELECT $[oige.U_APPROVAL.1]) 
               when @OBJECT = 14 THEN (SELECT $[orin.U_APPROVAL.1])  end)
Select Result from (select case when isnull($[$38.30.0],'')='210' and @PROCEED = 'Y' then 'TRUE' else '' end as Result
union
select case when isnull($[$13.10001004.0],'')='210' and @PROCEED = 'Y' then 'TRUE' else '' end as Result) as T1 where result <> '' order by 1 DESC
Am I on the right track or did you have a different idea?
Thanks.

Simon
