IDADPLAG35 - PGM pgm/application-name VER version-number is in use

Reason:

Another CA Ideal session is using the entity named, online or in batch. Underlying causes of this problem include:

Another user is actually accessing the entity. The access that the other user is performing requires that the entity not be shared or altered as required in your session.
You yourself might be the other user, if you are editing online for instance, and attempting to perform another manipulation in batch that must also retain control of the entity. This can also occur when operating in split-screen mode, where your CA Ideal screen's two regions act as different CA Ideal sessions.
An ABEND in a CA Ideal session left an outstanding enqueue on the named entity.
An enqueue against this entity exists in another region, and a unique QCODE was not specified.

Action:

Determine which of the above causes was involved and take appropriate action:

Have the users interfering with your command relinquish control. Otherwise, wait until the affected entity is no longer in use.
End activities of your own that conflict with your intended use of the entity.
See your administrator to DEQUEUE outstanding enqueues against the entity still left in force because of previous abended CA Ideal tasks.
See the CA IPC Implementation Guide for information on specifying unique enqueue names across systems.
