SBO_SP_Transactionnotifaction and Approval Procedures

Question

Hi,
I understand I cannot use SBO_SP to validate row level data in modules where the Approval Procedure are active.
Is there another way to do the following?
I have three header level and row level UDF's that I need to be validated before the users saves the document as draft in the approval procedure. Once the document enter the approval stages it can no longer be update to enter or change the UDF's, in the rows.
U_BU
U_DEPT
U_ProjectInv
Code being used fro other modules. I had to remove modules in approval procedure as documents would simply disaaper when saves as DRAFT.
MY CODE for non approval modules:
+++++++++++++++++++++++++++++++++
---+Force BU DEPT and PROJECT -- IN ALL REQUIRED DRAFT DOCUMENTS++++++++++++++++++++++++++++
IF @transaction_type IN ('A','U') AND @object_type = '112'
BEGIN
IF EXISTS (
select T0.Docentry
FROM     ODRF     T0     inner join DRF1 T1 ON T1.docentry = T0.Docentry and lineStatus ='O'
--select * from ODRF
WHERE
T0.ObjType in ('13','16','17','18','20','22','23','203','204') and
-- ('14','59','60','19''15', )Remove These object as SBO_SP is not compatible with Approval Proceedure
(T0.DOCENTRY = @list_of_cols_val_tab_del  and NOT(T0.U_BU IN (SELECT code FROM [@sg_BU] where code = T0.U_BU)))
or
(T0.DOCENTRY = @list_of_cols_val_tab_del  and NOT(T0.U_DEPT IN (SELECT code FROM [@sg_DPT] where code = T0.U_DEPT)))
or
(T0.DOCENTRY = @list_of_cols_val_tab_del  and NOT(T0.PROJECT IN (SELECT Prjcode FROM [OPRJ] where PrjCode = T0.project)) and not (T0.objtype in ('59','60')))
or
(T1.DOCENTRY = @list_of_cols_val_tab_del  and NOT(T1.U_BU IN (SELECT code FROM [@sg_BU] where code = T1.U_BU)))
or
(T1.DOCENTRY = @list_of_cols_val_tab_del  and NOT(T1.U_DEPT IN (SELECT code FROM [@sg_DPT] where code = T1.U_DEPT)))
or
(T1.DOCENTRY = @list_of_cols_val_tab_del  and NOT(T1.PROJECT IN (SELECT PrjCode FROM [OPRJ] where PrjCode = T1.project)) )--and not (@object_type in ('59','60'))
BEGIN
SELECT @Error = 1, @error_message = 'Business Unit - Department or Project missing from User Defined Fields or Rows'
END
END

Hector,
Sorry for the delay.
The reason I understand it cannot be done as there are postings indicating that SBO_Notifications cannot be used with modules running the SAP Approval Process. I have seen the result my self, with documents disappearing when added as draft with no error message.
If there is a way around this I would appreciate help to implement?
Kind Regards,
