Error not displaying while Invoice Apprvoal in detail tab

Question

Hi,
Here is the problem we are facing. We are at SRM 5.0 with Extended Classic and no IMS configured.
u2022 Activity u2013
1. Invoice with value more than PO value is posted and triggered for approval. Zero Tolerance  maintained.
2. Posted Invoice has status u2013 u2018To Be Corrected Manuallyu2019.
3. Work Item triggered for approval and is in Approver's inbox.
4. Approver approves the Invoice.
u2022 Expected Result u2013 If Approver tries to approve the Invoice then he/she should get error message u2018Document Contains Errors Approval Not Possibleu2019.
u2022  Actual System Behavioru2013
1. If approver tries to approve the Invoice at header level then error message u2018Document Contains Errors -
>Approval Not Possibleu2019 is getting populated. But we have deactivated the approval/rejection button at the header level.
2. Approver is opening up the invoice document and then approves the Invoice. At that time, error message mentioned in point 1 is not getting populated. Instead the message appears as u2018The Invoice Approvedu2019. This is a false indication to approver and work item remains in Approveru2019s queue.
Any solution to resolve this issue?

Hi AP,
Same approver when approves the Invoice at header level, error msg displayed properly. But if he tries to appove the invoice in detailed view - clicking on SAVE - then the error msg is not displayed and instead it shows Invoice Approved and workitem remains in his work list.
Is this because of Autho issue? In that case what autho objects we need to check?
My wild guess about this issue could be because system is not checking if the Doc is complete or not to trigger the respective message. Any thoughts?
Thanks.
