F1204 - Location Tracking Table - Object Account Field (OBJ)

Hi, how the field F1204.OBJ is populated and what is the purpose of this field?

I'm working with the R12108 Asset Transfert, to transfer assets locations.

The assets are transfered correctly and the location traking table is updated, but I can't find nothing explaining me how the field F1204.OBJ is populated, the value that i see in this field after the asset transfert doesn't make any sense, I was assuming this field would track the changes on the asset but the value is not the old account before the transfert.

Thanks

Michele
