SAP Error Message - Details

• Message type: E = Error

• Message class: AXT_MODEL -

• Message number: 030

• Message text: Field enhancement for place &1 is not possible due to database limit

What causes this issue?

Databases have restrictions regarding the maximum number of fields and
bytes of a table. For more information, see SAP Note 355898.

System Response

Each application defines a maximum number of fields and bytes that are
possible on a place for customers and partners when using the
Application Enhancement Tool (AET). This prevents AET users from
creating too many fields, which would cause an upgrade to fail in the
event that SAP delivers more database fields in a future release.

How to fix this error?

You have the following options:
Delete unused fields.
Reduce the length of existing fields.
Find a different place for the new field.

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