Hi,
I use custom developed solution, because I haven't found OOTB software, that would have fulfilled our needs.
I use Motorolla MC3000 to inventory of fixed assets in SAP ERP 6.0 with custom WinCE application which saves data in a file.
ABAP developer created an application that reads numbers from that file and matches them to EQUINR at SAP.
Whole processof comparingscanned data torecordsinSAP is executed by custom application too.
But if your client requires more functions you might be interested with other solution :
fully automated SAP Auto-ID Infrastructure for SCM.
