BMC Remedy ITSM 7.6.04 Service Pack 1 introduced changes to the underlying protocol.  The result of this is that the raw Remedy data can not be transformed to XML in the script which results in the "Network protocol/data error when performing data operation" error on replay of the script.

Support for BMC Remedy ITSM 7.6.04 Service Pack 1 has been introduced with SP82_Hotfix08_Remedy7604_SP1.  Please contact support to request this Hotfix.
