CNV_LTHCM_G_10040 - Overview

• Message type: E = Error

• Message class: CNV_LTHCM_G_10 - LT HCM: General Message Class

• Message number: 040

• Message text: Package ID &1 already exists as CWB package &2 '&3' in execution system

What causes this issue?

This package has an ID &1 that is identical with an already
existing CWB package ID &2 '&3' in the execution system.
However, further down in the process tree, when specifying the
conversion characteristics, the system must be able to create a CWB
package in the execution system with an ID identical to the current
package ID. As such a CWB package ID already exists in the execution
system, this will not be possible. Rather than waiting for this error to
occur further down in the process tree, an error is already issued here.

System Response

The system raises an error message. It is not possible to continue using
this package with ID &1.

How to fix this error?

The current package has to be deactivated, and a new package has to be
created.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
