what are the criterias to consider while deciding when to run the mrp?

Hello Friends,

Actually i was just thinking,if any company wants to run the mrp for planning than how to decide,when to run the mrp(daily,weekly,monthly).

One of the factor,while deciding this could be the raw material procurements,right?if they procure raw material once in a month than they should run the mrp once in a month.(even we can control this by keeping monthly lot size,if you run the mrp every week).

What could be the other reasons?

Thanks and Regards,
