Using this option makes that Archimede generates all materials needs for specific production order. Without generating needs Archimede user is not able to properly handle needs for production order (place purchase order for needed materials, or bind (book) those needs from the store if available. After process of generation needs is completed then Archimde informs about it. If some needs are not generated then Archimed also informas about it.
PLEASE NOTE: In case that an offer is being sent from CRM module into ERP module, become actual prodcution order, then Needs are generated automatically.
