Not sure it it exactly fulfill you requirements, but you can setup the operation with a work guideline of the type Subtask, and you set Sign Off Required = Required to Close Operation.

 Then you mark the operation as a Milestone. This will prevent a greater quantity being reported on the succeeding operations than reported on this operation

@Björn Hultgren thank you, I tried to add to a routing templet but it seems to not work with standard operation? Any suggestions?

Thank you,

@arebbeadle What problem did you experience with using Work Guidelines with Subtasks Required on Standard Operations and Routing Templates?

@Björn Hultgren  when I add a guideline sub task on a routing templet it removes the standard operation from the lineon the templet, 

If you use a Standard Operation as a reference on the Routing Template, you must add the Work Guideline to the Standard Operation.   

Thank you @Björn Hultgren .
