Hi Alka,
You did not mention that the asset was fully depreciated. Is this another asset?
If the Asset is fully depreciated, indeed the value might become negative. There is a setting in the parameters to allow negative value, but I would suggest to not use this.
If it has been fully depreciated, I assume you could have the next Asset values:
Acquisition value: 5500
Depreciated: 5500
In fact there is nothing to post, other than reducing both balance accounts for Aqcuisition and Cumulative depreciation. Why would you post the Asset value to another account if it is already fully depreciated? As it is fully depreciated, it will not change any Profit & Loss account.
If you dispose 1 out of 10 (10%), normally you post in summary:
Acquisition value: -550
Depreciated: -550
You can achieve this by creating one asset journal and first create a line for the Depreciation adjustment and then the line with the Acquisition adjustment. This to be sure AX will think there will be no negative value.
(it was zero, depreciation adj - acquisition adj). If you don't specify the offset account, AX will take one voucher.
