Once you have uploaded an XSLT file, it is stored as an object in Workday. If you make changes to the file outside of Workday, you must upload the new version to replace the existing file stored. You execute the Edit XSLT Attachment Transformation task. This will enable you to upload the new version without creating a new object. No additional edits are needed to the integration system itself.

EIBS: RUNTIME BOUNDARIES ON EIBS WITH CUSTOM XSLT TRANSFORMATIONS 

When you transform very large amounts of data, outbound EIBs with custom XSLT transformations consume as much as 10 times the amount of memory that the source data requires. Workday recommends that the amount of data transformed not exceed 100 MB. Although EIBs that transform more than 400 MB of data have a high risk of malfunctioning, Workday still attempts to complete all EIBs. The maximum amount of memory that is allocated to an EIB transformation is 15 gigabytes (GB). 

An EIB's custom XSLT transformation portion can process for up to 2 hours. Custom XSLT transformations that spend more than 2 hours processing are terminated automatically. 

We recommend that you take one or more of the following steps to avoid malfunctions: 

·       Run the EIB with different filters, using either custom report filters and/or launch parameters to filter the data source to reduce its size. 

·       Review your custom XSLT for possible processing inefficiencies. 

·       Consider converting your EIB to a Workday Studio integration.

 If you are in the process of designing/developing Workday integrations, please consider the future growth of your data when choosing between implementing on EIB vs. Workday Studio.
