Maintenance Plan - Back ground scheduling - Task List long text

Hi,

We create a Maintenance Plan for a Technical object with  a Task List.

In header of the Task list, description of the task list has been created with Long text information.

We do a background scheduling for this Maintenance Plan. When Order is created from this Maintenance Plan, the long text information from the Task List  is not flowing to the Long text information to the description of the Order. When we click the Long text, we get a pop up "Long text does not exist" -

Message no. CP752.

We need the Long text information from the Task list to the Long text description of the Order, while processing the Maintenance Plan through Back ground job.

Kindly suggest.

Raja.
