Title: "de-serialized object" error while try to open Cognos schedule in 3-rd part apps
Post by: karine3001 on 04 Mar 2026 04:23:58 PM
Hello everybody
We use IBM Cognos v.11.1.7
We have a main goal to optimize the Enterprise report system by dropping or editing schedules with very high frequency or with very large periods of dates. Now in our system there are 3140 schedules created by business-users. The original reports are located in different folders. An usually business-users make a copy of original report and save it in their own folders, and then create a schedule for that copy
For that purpose we use MotioPI third-part application - to found the schedule, its creator and the original name of the report, from which the copy was made
But recently we faced a problem with "deserialized object" - when the xml of the object is getting invalid and third-part application cannot open it (while the native Cognos apps can open it without any problem)
here is the description of the problem: https://support.motio.com/portal/en/kb/articles/motiopi-error

The question is - what can cause this error and what can we do to prevent it?
