Method ENQUEUE

Use

The ENQUEUE method locks the current object. The lock only refers to the relevant main table (such as table TBRF150 in the case of expressions). The dependent additional or specialization tables (such as tables TBRF150T and TBRF144 in the case of expressions) are not locked as well explicitly.

The reason for this is as follows: In the BRF, no isolated access to specialization tables takes place. This procedure is therefore sufficient to prevent competing write access attempts.

The implementation of the basis class is sufficient here as well. This means that you do not have to redefine this method.
