How To Fix PK460 - Creation of several planned orders with one action is not possible

SAP Error Message - Details

• Message type: E = Error

• Message class: PK - Production - KANBAN

• Message number: 460

• Message text: Creation of several planned orders with one action is not possible

What causes this issue?

According to your settings, the system is to create several planned
orders in one posting step. However, this is not possible for technical
reasons. The reasons for this behaviour could include:
You defined in the control cycle that the rounding quantity is a real,
integral multiple of the fixed kanban quantity.
When creating the event-driven kanbans, you entered a quantity that is a
real, integral multiple of the fixed kanban quantity.
In the replenishment strategy, you defined that a load carrier
corresponds to a kanban and when creating the event-driven kanbans, you
entered several load carriers.
This results in several kanbans and therefore several planned orders
being created in one step.

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?

Set the system so that when using the replenishment strategy <LS>Process
with Planned Orders/Planning with MRP</>, only one kanban is created
per posting step and, therefore, only one planned order per posting step
is created.
