SAP Error Message - Details

• Message type: E = Error

• Message class: WX - Master data maintenance: Plant

• Message number: 496

• Message text: Plant cannot be extended using this transaction

What causes this issue?

You probably want to maintain a plant which you have already created as
a customer in SD. You cannot extend this using 'Create' transactions.

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?

Check that your entries are correct.
If necessary, maintain your data using customer transactions.
If you want to change a customer into a plant, contact your system
administrator. The system administrator can, if required, create an
entry in table T001W which references the customer concerned. The
customer is thus linked with plant master data processing and can be
processed using <ZH>Change</> transactions.
