Depreciation is not posted in spite of planned depreciation

Hi,

I have an asset number that have planned depreciation for year 2009. I saw it in AS03 in asset values. But in spite of running transaction AFAB in all their options (planned, repeat, restart and unplanned posting run) i receive the message that their is not areas to post in company code GN23.

All seems to be all right with that asset. Can you tell me what possible i am doing wrong?

Best Regards

João Fernandes
