I know this has been posted here for a while but in case someone encounter the same issue just like I just did.
Here is what I did to get this one fix. Go to Fixed Asset No. (Fixed Asset Card), and click Ledger Entries to see all the entries have been entered for this FA. Check for the last date on the list. The Disposal Date must be later than that date. That means the posting date in the Sales Invoice (for FA Disposal) must be later on the that last day. Hope it helps.
This issue is been pending for long, but still posting it as it may be helpful for seekers…
This error appears when you have done depreciation for a month and trying to sell the FA prior to depreciation month.
the solution for this is to cancel depreciation entries rather than reversing depreciation entries. the cancelled entries will not be available in General Ledger entries but will be available in error ledger entries in FA card.
then try to dispose the entry through fa GL journal…
