The xAssets API - Method : AssetAuditXML

Summary

Generate a table of Asset History information for an asset or a list of assets

xAssets stores each instance of an asset record every time it is saved, so a full audit trail exists for the asset in a history table

Use this function to query the asset history. You can query for a specific field or for all fields, and over all time or over a specific time frame

Any number of Asset table fields can be added to the data

Parameters

Parameter : sArguments

"ASSET" to return data for a single asset or "FIXEDLIST" to return data for a list of assets

AssetID or List of Asset IDs, comma separated

Flag for whether to report all changes(false) or just most recent changes(true)

Text to use for when the asset was created (defaults to "First Version")

Transformation to run and then rollback after the report is created (for impact assessment)

Asset Table Field name we are reporting changes for

Days to report (eg 60 = most recent 60 days) 0 = All

Fields to report history on. If left blank, this will return the WhatsChangedField. It can also contain OldValue and NewValue. Any other fields are taken from the new asset record. e.g. Arguments(7) = "WhatsChanged,AssetRef,OldValue,NewValue"

Returns

Asset History XML in standard format
