When a template for a work ticket is planned, it may often be possible to begin a step before the previous step has been completed. The degree to which a step may begin before the previous step has been completed is referred to as the overlap percentage. A 100 percent overlap means that a step is scheduled to start simultaneously with the previous step. A 25 percent overlap indicates that a step is scheduled to start when the previous step is 75 percent complete.
You can control the overlap percentage allowed for a step using the Overlap Percent field on the Work Ticket Entry Steps tab. You can also maintain the overlap percentage for a standard template step using Work Ticket Template Maintenance.
Note An overlap percentage entry for the first step in a template has no effect because there is no preceding step. Overlap percentages are also ignored when multiple activities are performed at the same center.
Example
The first step of a work ticket requires 40 hours of time with a start date of 5/11/28, and the work center for the step is available for 8 hours a day. The second step requires 16 hours of time at a different work center that also operates for 8 hours a day. If the overlap percentage on the second step is 25 percent, the start date for the second step is calculated by backing out 10 hours (for example, 40 x 25%) from the completion of the first step. The following table compares the scheduling for the two steps first with 25 percent overlap and then without any overlap.

Although the start date for the second step is 5/14/28, only 2 hours were scheduled for that day. With 0 percent overlap, the second step cannot start until the first step is completed.
