How To Fix AD487 - Table of activation type 1; use C program to generate nametab

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 487

• Message text: Table of activation type 1; use C program to generate nametab

What causes this issue?

This ABAP/4 Dictionary table is protected with activation type 1. This
means that this table may not be activated online by the activator if
the modification is relevant to ABAP.
Nametabs from tables (run-time objects), which the activator itself
uses may not be regenerated as part of the activation run, as the
activator may then take away its own basis (nametab of the table),
resulting in abnormal termination of the activator.

System Response

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?

The nametab of the table must be regenerated using C program DIPGNTAB
(the correct TWO_TASK must be set). Then the ABAP/4 Dictionary version
of the table must be activated.
