Service Tax Accounting not reversed in AR on in-complete transaction

Hi

We are on Version 12.1.1

1. Responsibility - India Local Receivables

2. Form - Transaction Localized

3. Create transaction and attach inclusive Service Tax

4. Complete transaction, The following accounting entry generated:

Debtor A/c     Dr.   1000 (Total Amount including tax)

     To Revenue              1000 (Total Amount including tax)

India Localization entry in GL Interface

Revenue       Dr     100 (Service Tax Amount)

     To Service Tax            100 (Service Tax Amount)

Entries are ok

5. Now if we in-complete the transaction and complete again, the system generate India Localization entry again without reversing the previous entry

6. Means everytime we incomplete and complete the same transaction, one India Localization Entry generated without reversing the previous
