KB196412593: Device Manager - Submitting merged plate to CDI fails with is.st.mismatch: Current XMP differs from XMP (in DB) at submit time

Summary

A merged plate is created by the Plate Merger. The "Submit to CDI" task fails with the message "is.st.mismatch - Current XMP differs from XMP (in DB) at submit time". 

Symptoms

Submit to CDI task fails.

Details of the task contains entries like:

• Mismatch detected for xxxxx-xxxx-xxxx-xxxx-xxxxxxxx : Current XMP of \\server\container\folder\filename_separation.len differs from XMP (in DB) at submit time.
• Detected X mismatch(es) on image file(s).

Log file of the task contains entries like:

• is.st.mismatch1 xxxxx-xxxx-xxxx-xxxx-xxxxxxxx : Current XMP of \\server\container\folder\filename_separation.len differs from XMP (in DB) at submit time
• Detected X mismatch(es) on image file(s)

Root Cause and Solution

Root cause:

The LEN file (and as a consequence also its XMP) was changed after it was originally submitted to the Plate Merger. This is not allowed (for obvious reasons: merging is done/decided based on data (size, screening, ...) in the XMP, if the final LEN file has different properties than the one used to create the merged plate, it could possibly no longer fit the merged plate, or the CDI technology, or... 

This should be easily traceable by comparing the "Launched Date" in Press Plates view to the LEN file's Modify Date. (or look for tasks in the task list for this/these file(s)).

Solution:

You will have to re-submit the files (can be done from within Press Plates view) and merge them again.
