ledger differences

HI my friends!

I have 2 ledgers at my company, one ledger 00 in USD and ledger 09 in EUR. When i post the document .. i can see the post at both but when i look via OCCM, have some differences .. so ..

at account XXX value is 1000 at ledger 00 USD and 1000 at Ledger 09 EUR difference 0

at account YYY value is 0 at ledger 00 USD and 500 at Ledger 09 EUR difference 500

at account ZZZ value is 500 at ledger 00 USD and 500 at ledger 09 EUR difference 500

DEB 1000 at ledger 00

Cred 1000 at ledger 09

Difference 0

Always when this happens i must delete the ledger 09 EUR... and create again .... then this problems dont happens...

This problem happens with Somebody ?

my best Regards
