Hello Mariano,
thank you for your explanation. Now I do understand how does work MRP with scheduling "1" and scheduling "2".
About one thing I would like to make sure. Let´s suppose that there will be maintained different operation time in master material and different operation time in routings - the same material, or even it will differ as well by some operation.
Will MRP with scheduling "2" calculate with operation time + operations from material master or from routings? And as well then what operation time will be taken into consideration while creating material standard cost estimate. This would be quite interesting to know - I just would like to understand how does this work.
BR,
Paulina
