Table & cannot be edited using the old standard maintenance

What causes this issue?

You are trying to edit a table using obsolete table maintenance. This
is only possible if an old maintenance interface still exists for your
table. However, this is not the case.

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?

If there is a standard maintenance dialog defined for your table, you
can start it using the menu (<LS>System -> Servvices -> Table
maintenanc
e</> or the IMG (Transactions SM30 or SM34).
If you have created your own table, you can generate maintenance
interfaces for SM30 and SM34 maintenance automatically using the ABAP
Workbench (Tools -> ABAP Workbench -> Development -> Other tools ->
Generated table dialog</>.
