Fixed Asset migration - Merger between Companies

Dear All,

I am working for a company which recently acquired another company which has a different ERP system and want to merge their assets into our present company code.

I read that a possibility to upload the assets is to create assets manually and then use ABSO T-code with transaction type 148 to upload the balances.

I am doing some testings but I am having problems with the depreciation that is calculated after the migration.

All the assets that I have to create are capitalized in the current fiscal year.

Any suggestions?

Thanks,
