SAP Message AD370 - Active nametab is missing. Nametab was re-written

Diagnosis
When activating this table, it was found that the active nametab ofthis table is missing although the table already existed in an activeversion in the ABAP/4 Dictionary. The nametab could be missing for thefolowing reasons:
The table was new and was activated using the mass activator, where theoption 'nametab inactive' was marked when the program was called. Themass activator works in 2 steps. All the innerreferences of the table are made in the first step. When this hasbeen successfully completed, the table is activated. The nametab ismarked as an inactive nametab. After a successful check of the externalreferences of the table in the second step, it is found that only oneinactive nametab exists, but the active nametab is still available.
Inconsistencies between ABAP/4 Dictionary definition and the nametab.
This can happen for example if the import and the activation after anupgrade were not successful or were not completely executed.

System Response
The activator only sends this message for information and generates anew nametab.

Procedure
Case 1: The message is an information message. No action is required.
