In the fixed assets area, reclassifications of fixed assets (from one group to another) are covered by a functionality in D365 (mainly from "under contruction" to the final asset group), not by a posting entry.
However, from financial reporting perspective reclassifications need to be tracked as postings. This means, we need to define
1. Reclassification (gross acquisition cost) and
2. Reclassification (cumulative depreciation)
as additional posting types, to be tracked in the GL and to be reported on in the asset balances.
This is very much a standard requirement. Since this requires at least 4 posting transactions, the background postings may be defined similar to disposals where also some additional postings to the sales/scrap main account entries are done.
