Now check whether the change document flag is set for the corresponding data element in the Dictionary for the fields whose changes are to be logged. This is necessary so that the object-specific function modules can identify which field of the defined object should be entered in the change document during logging.
If the flag is not set, you can change it. The flag becomes effective after the activation.
If the flag is set by hand, it can have undesirable side-effects: If a table field in another application, which is based on the data element in question, belongs to a change document object, but was not previously logged, setting the flag will start logging in this application as well.
It is therefore important to consider whether data elements are, or could be, change-relevant when creating them, and to set the flag accordingly. If the data element is not in any change document object via a table field, this has no negative effect on the system.
