AssetWise APM asset mass data upload

Myself and our support group are attempting to upload assets into our APM 7.5 TEST environment.  We've been unsuccessful to date with the process.  It appears that a batch job needs created to kick off the upload.  We've spent some time trying to create but no success to date.  Has anyone successfully used the mass upload feature in 7.5 for assets and perhaps provide insight into the process and requirements?

Thanks
