Symptom
When you post to an asset, the system raises the error "AA031 Error when reading fiscal year & for main number &".
Environment
SAP S/4HANA CLOUD
Cause
The reason is that the asset was created when fiscal year 2019 is closed, then you reopened fiscal year 2019 and capitalized the asset in 2019. However there is no entry for this asset in 2019, so there is no way to do any posting in 2019.
Resolution
The asset can't be used any more, please create a new asset to replace it with fiscal year 2019 open.
Please notice that if the legacy transfer date is 31.12.2019 then 2019 should not be reopened as all postings for 2019 and prior fiscal years should already have been included in the take over values posted.
