Is there any option available to create a constraint capacity pla in ASCP including 'Bottleneck resources' (upart from resources which have been defined in item routing). I tried by assigning Bottleneck resources option in Constraint tabbed region. But system keep on showing a message nos with msg " Must enter Bill of Resource". If this is possible, is there any possibility to visualze/view the bottleneck resources especially in my capacity planning in 'Planner Workbench'?. Kindly help me out in this.
