Wrong creation of legacy asset in AS91

Hi ALL,

I had create an asset using tcode AS91 and the system assigned main asset number 50000001 automatically to it. Later on, we discovered that we do not want this asset migrated to SAP. (Not yet post to asset reconciliation account in GL) Therefore, by using tcode:AS92 i remove the values for all fields in the 'Takeover values' screen.

The problem is since the main asset number 50000001 has been created in SAP and we would like to use it for normal asset creation. Is it possible for me to change it using AS02 and post value to it through F-90?

Please advise.

Thanks in advance.
