You can either select the Best Quantity indicator with a Min. List Status, or, you must select a specific Issue Status. Best Quantity indicates the latest information available. However, it may make sense that you need to generate requisitions for the final BOM material only, in which case you would need to specify an exact Issue Status.
With the Only End Nodes indicator, you define whether all BOM nodes (indicator not selected) or only terminal BOM nodes (indicator selected) is processed. It is possible to store material at any node level of a BOM structure, although typically you would only store material at the end node. For example, during the first material take off from PDS, there are positions created on the node level pipe. Later in the design, when isometrics are created for each line, the positions appear under the lower node ISO. Using the Only Endnodes function ensures that only the lowest node is used for the requisition calculation.
If you select the 100% BOM Pos indicator, the MTO job fetches all BOM positions that do not satisfy any of the assigned (material) where conditions and copies them into a separate table. The contents of this table can be displayed after the MTO job is completed by clicking the Bad BOM Pos button at the bottom of the Job Control section.
