Wrong update of FMAVCT table

Hello

In ECC6 version I have a probelm with postings into FMAVCT table.

Example: I opened EMF for 100 $ and then Pur. Req. for 20 $.

I expect to see in FMAVCT (under my user specific ledger) value 100$,

but I see only 80 $ (e.g. 100-20).

In addition in FMIOI and FMIT tables I see right values - sum of all

lines is 100$, and if I do RECONSTRUCT I get after this right values in

FMAVCT.

May be you know what is the problem ?

Thanks.
