Cannot Delete / Cancel / Reverse Service Purchase Order. Please Help....

Question

If you create a service entry sheet, process the service entry
approval,post an invoice for an amount greater than the Service entry
then, cancel
the entry sheet and add a new service specification (i.e. same entry
sheet), the following problem occur:
1. You can no longer cancel the invoice if the services of the entry
sheet are deleted.
2. After changing the entry sheet and renewed acceptance of services
performed, a posting takes place where the value differs from the
value of the entry sheet.
Steps to Reproduce:
1. Create a Service Purchase Order of $2,675.00
2. Create a Service Entry against the Purchase Order for $2,675.00
3. Approve Service Entry against the Purchase Order for $2,675.00
a/c postings Dr Expense $2,675.00
Cr GR/IR $2,675.00
4. Create an Invoice against the Service Purchase Order for $6,452.50
a/c postings Dr Expense $3,777.50
Dr GR/IR $2,675.00
Cr Vendor $6,452.50
5. Create Credit Memo $1,537.00
6. Revoke the Service Entry against the Purchase Order for $2,675.00
I am expecting the Reversal of the Service Entry figure is $2,675.00, but instead, the Reversal of the Service Entry figure is $1,537.00. Why is that so? I need to be able to Reverse/Delete the PO. Please help...
Thank you.
