Why did the asset not make any adjustments, but the depreciation was rolled back.

One asset was adjusted in 2018 and has not been adjusted so far, but depreciation is automatically rolled back at the end of August 2020.Upon enquiry, it was found that the depreciation of the asset in August had been passed on to GL, and the journal approval for depreciation of the asset could also be found in GL, but the account generated by depreciation of the asset was queried from FA Finance, but there was no journal approval. Equivalent, the journal lot name is not written back to the FA.It is not clear whether this is related to rollback depreciation.
