Period Start labels
An instant-type element of the primary axis that has a period start preferred label (see 6.12.7) results in a special kind of layout and column merge called a movement analysis. In a movement analysis, duration-type facts are matched to instant-type facts whose date-times are the same as its start and end dates. The same fact may thus appear as the ending value of one column, and the starting value of another. In the example below, the fact shown as YYY,YYY at Dec 31, 2012 is at the end of one period and the start of the next:
USD |
12 mo.
ended
Dec 31,
2013
|
12 mo.
ended
Dec 31,
2012

period:

YYY,YYY |
xxx,xxx |

Balance, end of period: |
zzz,zzz |
YYY,YYY |
In general, the starting and ending balance facts should be matched with at least one fact representing the duration between them, otherwise a warning may be issued (6.26.2).
Note that the order of elements along the primary axis is preserved and does not affect whether the layout is considered a movement analysis; the following example is equally valid, resembling a statement of cash flows:
USD |
12 mo.
ended
Dec 31,
2013
|
12 mo.
ended
Dec 31,
2012
