GRNI G/L Acc not automatically clearing (reconciling)

Hi Everyone

My GRNI account is continuing to build up and build up transactions without automatically reconciling itself.

(I.e.: the Credit posted from the GR PO is not automatically reconciling with the Debit posted from the AP Invoice.)

What could be the reasons for this?

Is there a tick box I’m missing somewhere perhaps?

I found this thread http://scn.sap.com/thread/1575608 which has a similar issue but the solutions are inconclusive.

To try and cover what I done so far:

1. My G/L Account Determination Allocation Account is posting to my GRNI Account, this is both at the main level and at the warehouse level as set by my Item. The warehouse has been ticked as Nettable.
2. I have done an Internal Reconciliation to manually reconcile the all Debits and Credits in the GRNI account so I’m left with just the open items (or GRPO’s where there is no Vendor/Supplier Invoice received yet)
3. I have run the SQL query from the thread above which pointed me to two JE entries which I’ve also manually reconciled.
4. My SAP Version is 8.81 PL:08

One possible solution offered in the thread is “You need to check the links between GRPO and AP Invoices.  Some links must be wrong or broken.”  - Does this mean the base and target document links in both the document row tables could be incorrect?

Any further help will be gladly received.

Thanks
