How To Fix AD448 - Errors occurred when activating table &

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 448

• Message text: Errors occurred when activating table &

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

The table should be reactivated, so that the nametab can be rewritten.
You must eliminate any errors before regenerating.

What causes this issue?

This table was activated using the mass activator. The mass activator
works in two stages. During the first stage, all the internal table
references are performed and, if successful, the table is activated
after the nametab has been deleted. If, during the second stage, the
external references are successfully checked, the nametab of the table
is then rewritten.
In this case, the nametab for this table is missing, since the external
reference check could not be successfully concluded.
