How To Fix PK103 - Warehouse number changed from &1 to &2 according to IM-WM interface

SAP Error Message - Details

• Message type: E = Error

• Message class: PK - Production - KANBAN

• Message number: 103

• Message text: Warehouse number changed from &1 to &2 according to IM-WM interface

What causes this issue?

A warehouse number is assigned to a combination of plant and storage
location in the IM-WM interface. The system uses the production supply
area to determine the storage location.
Provided the storage location is managed by WM, the system can use both
settings to uniquely determine the warehouse number. Another warehouse
number makes no sense in the WM-PP interface.

System Response

The system has used the current setting of &V1& to change the warehouse
number to the logical value &V2&.

How to fix this error?

Check whether the other input values for the control cycle are correct.
The system makes the formal checks independently when you save your
data.
