fixed asset data in SAP B1 9.1 PL05

Dear Experts,

I want to know if fixed asset data of previous SAP B1 9.1 PL05 version can be used.

It is because we want to upgrade our SAP B1 version

We have made some upgrade tests but we are surprised why our assets data in previous version are not available in SAP B1 9.1 PL05 after fixed asset is enabled. I've checked sap note 1903799 but failed.

Please help to solve this issue.

Thank you.

Regards,

Steve
