The activation type defines whether the table can be activated directly from the ABAP Dictionary, or whether the runtime object of the table must first be generated with a C program. This entry is optional and only important for tables of the runtime environment.

The following entries are possible for the activation type:

• Tables having activation type 01 cannot be activated from the ABAP Dictionary. The runtime object must be generated using a C program. The table can then be activated from the ABAP Dictionary. This activation type ensures that important system tables cannot be changed and activated directly.
• Tables having activation type 02 are also used in C programs. The data structure in the C program must therefore be adjusted manually when the table is changed. There is a relevant comment in the activation log for such tables.
• Tables having activation type 10 are needed before R3TRANS runs. Such tables must exist before all other tables when upgrading.
• Tables having activation type 00 can be activated directly from the ABAP Dictionary. This is the default setting for the activation type.
