Table 146 lists the types of actions written to the outline change log and the information included in the log message.
The outline change log program reads outline information from left to right. If you are looking at an outline, the left sibling is the sibling directly above (to the left of) the newly added dimension or member. This rule does not apply if the immediately preceding dimension or member is a parent. If a newly added (or moved) member is the first child of its parent, or if the member is the first dimension in the outline, the outline change log identifies the old location of the dimension or member as None.
