Asset with no values still depreciating

Hi All

I have a strange issue where asset is depreciating even though there is no acqisition value.

Asset Explorer-

It shows no values.

Even shows nothing was posted.

No activity shows at AR02 or S_ALR_87012936.

However it shows value posted at G/L level.

Even shows depreciation to be posted for 4th period.

Regards

Pankaj
