KH339 - Overview

• Message type: E = Error

• Message class: KH - CO-PA Reporting

• Message text: Lock problem: Report &2 was not generated

What causes this issue?

Due to changes made, you need to regenerate form &V1& or report &V2&.

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

To avoid errors occurring, the system checks the current lock situation
when it generates. If a lock entry already exists -- in this
case caused by user &V3& -- you cannot generate the report.

System Response

The system terminated generation. You cannot continue the current
transaction.

How to fix this error?

The situation will no longer occur as soon as user &V3& has finished
generating the report. Try processing report &V2& again in a few
minutes.
