The Sales and Operations Plan function is concerned with determining the quantity and timing of production for the intermediate future (from 3 to 18 months ahead). This planning process is aggregate in the sense that it is focused on the global production flow for the most critical resources. This plan has to take into account the main demand evolutions (trend or seasonal fluctuations) and to identify the most efficient strategy to cope with these (build inventories to absorb changes, change the size of the workforce, consider overtime or idle times,).
To use the Sales and Operations Plan function you have to create two new types of items: the Family items and the Resources items and three new BOMs (Planning BOM, Resource BOM and Commercial BOM).
It is worth noting that these aggregate plans can be transformed into production plans using a specific disaggregation procedure BOMs (S&Op Plan Disaggregation function, S&Op Plan menu).
