Foriegn Currency Valuation Ecc 6.0

Question

When we carry out foreign currency valuation with the FAGL_FC_VALUATION .
It generates the following postings:
DB Unrealised Gains  10 ( Example Amount )
CR Adjustment account  10 10 ( Example Amount )
So far so good.
As part of the delta logic at the time of payment/clearing system should post the following posting:
Dr Vendor 200 (the full invoice amount)
Dr Unreal gain 10 (reversal of previous entry)
Cr Bank -190 (Invoice amt - gain from reval)
Cr B/S adjustment -10 (reversal of previous entry)
Cr Realised gain -10
The question now is system is not passing the above entries. Instead of that system, only passing following entry.
Dr Vendor 200 (the full invoice amount)
Cr Bank -190 (Invoice amt - gain from reval)
Cr Realised gain -10
In our case System creates adjustment postings (to reverse the difference due to valuation previously posted) in the subsequent valuation run.
Instead of that we want entry should be posted at the time of Clearing.
Please Clarify.
