Our xml file was rejected for MANIFEST-025: Manifest 'ChecksumAugmentationNum' must match the IRS-calculated 'ChecksumAugmentationNum' value of the transmission. We had our IS dept generate a new check sum, updated the manifest xml file and resubmitted. This file was rejected again along with the same MANIFEST-025 error. After being on hold for over an hour with the IRS the Benefits analyst was told to submit a replacement file. I ran a new BN299 as a replacement and linked it back to the original rejected IRS Receipt ID. Still Rejected! Same MANIFEST-025 error. Any ideas?
