PK293 - Overview

• Message type: E = Error

• Message class: PK - Production - KANBAN

• Message number: 293

• Message text: Last kanban signal cannot be reversed

What causes this issue?

You can only reverse a kanban signal if the system still knows the
previous status. In certain cases, this is not the case. For example:
if a reversal was carried out for the previous kanban. (It is always
only possible to reverse the last status change.)
if the previous kanban was processed in the kanban correction.

System Response

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

How to fix this error?

Analyze the actions to be carried out in the reversal (status change,
reversal of a goods movement, deletion of a replenishment element) and
carry out these actions manually.
