In IFS10, shortly after upgrading from IFS8:

When we go to an active Task Schedule with a single task, Create Order Proposal, and attempt to add a day, change the time it executes, or alter the schedule in any way we receive the error message, “The Batch Schedule Par already exists.”
 

The SQL trace comes back clean in the debugger having successfully run the validation method on the database task.


Deleting the task schedule and database task in an attempt to recreate the job results in the same error message when attempting to reconstitute the task schedule.

Most probably this issue may be Due to the migration PMRP database tasks still using old data that came from the migration. If you deleted the existing database task schedule and recreate it this issue gets resolved.

When doing changes to an already created “Database Task Schedule” application will internally call validate parameter method to verify all the parameters are valid for the database task. This database call is executed based on the parameters defined for the database task by the IFS F1 framework which saved in F1 framework tables.
Most probably these tables still contain values for IFS Application 8 version & should be corrected.

But to confirm this assumption, it should be investigated further
Then we can give a proper Answer\Solution.
Please log an IFS support thicket.


Kelum,

Thank you for your response. Unfortunately, deleting and recreating the Task Schedule results in the exact same error message on attempting to save the new Task Schedule. Furthermore, deleting the Database Task itself and recreating it also makes no difference.

To that end, and with your note at the end, we will be logging a support ticket.

Hi @m.m 
OK Matthew 

A similar issue has been addressed in below IFS solutions.
 Solution 286453 - UPD10 Bugfix
Solution 287257 - UPD11 Bugfix

But as I mentioned earlier it's better to investigate the issue further through a support ticket. Then IFS support team will investigate the issue further and will give a proper answer/solution.


Any solution found for above issue?
