This function enables one to find the origin of each Work Order or Purchase Requisition planned by the MRP calculation.
When opening this window, the planned orders calculated by the MRP function are listed. They are preceded by the sign +. To visualize the origin of each requirement, it is necessary to click on this sign. One repeats this up to the upper level, i.e. the customer orders or the forecasts.
One can close a branch of the tree structure by clicking on the sign - again.
The Expand All button permits one to display the complete tree structure.
The Collapse All button displays only the first level.
