| # Level of detail For several concepts, you can vary the level of detail. For example, you can define the number of BOM levels, the number of cost components, the number of reconciliation groups, or the number of clusters and plan items. Sometimes a multilevel BOM is required and is very beneficial. However, more BOM levels require more transactions, which makes performance worse. Therefore, be careful adding when extra levels of detail, and, if possible, look for alternatives. For example, for some warehouses and plan items you do not need MRP to plan them. You can consider other planning mechanisms such as TPOP, SIC, or order controlled/single. In LN, you can apply very detailed modelling. For example, in Tax Exception Modeling, if you must deviate from standard tax logic, you can specify which tax code is applicable in which situation. However, detailed modelling requires the specification of a large number of rules, which slows down performance. If you must deal with exceptional cases, it is best to do manual corrections. |
