SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 370

• Message text: Active nametab is missing. Nametab was re-written

What causes this issue?

When activating this table, it was found that the active nametab of
this table is missing although the table already existed in an active
version in the ABAP/4 Dictionary. The nametab could be missing for the
folowing reasons:
The table was new and was activated using the mass activator, where the
option 'nametab inactive' was marked when the program was called. The
mass activator works in 2 steps. All the inner
references of the table are made in the first step. When this has
been successfully completed, the table is activated. The nametab is
marked as an inactive nametab. After a successful check of the external
references of the table in the second step, it is found that only one
inactive 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 an
upgrade were not successful or were not completely executed.

System Response

The activator only sends this message for information and generates a
new nametab.

How to fix this error?

Case 1: The message is an information message. No action is required.
Case 2: Find out why the nametab is missing to prevent inconsistencies
of this type occurring in future.

  Transport Issues: If the object was transported from one system to another (e.g., from development to quality assurance), and the nametab was not included or activated in the target system, this error can occur.
  
  
  Development Environment Issues: Sometimes, issues in the development environment, such as missing authorizations or incomplete object definitions, can lead to this error.
