Summary :
The SAP Note addresses performance issues in materials planning, identifying multiple organizational and technical factors affecting runtime. Key organizational aspects include the type and mode of planning runs, updating frequencies in the Purchasing Information System, and the impact of parallel processing. Technical facets include hard disk response times, database management, buffering, and specific program errors. Solutions are recommended through note implementation and system adjustments. Organizational measures like reduced planning horizon and selective regenerative planning are advised alongside database and hardware assessments to optimize materials planning performance.
Key words :
production -> material requirements planning -> planning -> mrp calculation -> define planning horizon, production -> material requirements planning -> planning -> scheduling, capacity parameters -> define scheduling parameters, statistics update takes place automatically, terms material requirements planning, buffering sap number rangesb4, incorrectly configured hard disks, a5during lead time scheduling, specific performance problems solution, create mrp lists
