I just got started using MRP and for the most part we have everything running correctly. There's just a couple things i can't seem to get figured out/don't seem to be working as expected. • our WO are completed and picked up in full on our end date. NS is creating planned transfers before the end date of the WO. I know i can set lot sizes as our MOQ which will tell NS the lead time is for that MOQ size, but how do i tell NS the lead time is for the full order qty? I feel really dumb playing with lot sizes and variable lead time, i just think i'm missing something simple, but this is really throwing off our calculations. at least the timing of our inventory availability • we want to be able to tell NS to stop producing something. I figured that setting all BOMs to have an end date would tell NS that there is no available revision after a certain date and that we would not be able to get any more supply. i know the simple answer is to set demand to 0 after a certain date, but i still want to move remaining inventory through our network, i just want to stop producing new inventory despite demand. I hope that makes sense. these are my 2 big blockers that i just can't seem to find the answer to which is causing some hesitation from my team to embrace the tool fully. can anybody give me any advice? Really i'd love to spend 15 minutes with somebody who knows MRP to just help me clear up some of these gaps. Any advice would be greatly appriciated

1. could be due to the transfer lead time in the planning rule group (Lists>Supply Planning > Planning Rule Group) The transfer rule could have a lead time in days that is giving you a transfer signal early. Is it transferring to meet demand in another location? Ultimately if you want each work order to take the same # of days regardless of quantity then you should use location fixed work order lead time. So then MRP would give you a work order for the transfer lead time + location fixed work order lead time to get a start date and then that would give you the transfer lead time window to move it to the final warehouse.
2. Hard to say without knowing more about what you are actually doing with MRP.

Thanks for the response! 1. this is exactly how i thought it should be working but i still see the workbench planning transfers before the end date of the WO. My settings for WO items are fixed lead time is set for the location, and the production location to the next location is defined in my rule group with a lead time. so example fixed lead time is 7 days, transit time to next location is 7 days, the start date of planned WO is 14 days as expected, but then planned TO to next location is the start date of the WO for a portion of the planned WO. is there another setting that could be interfering or that needs to be set to say my production lot size is 100%, i know you can set specific qty. It's just frustrating because you explained exactly how i expected things should be working. 2. Right now our main goal of MRP is to get our production planning and component purchasing under control. quick overview of our network: a. components are purchased and sent to storage location b. components are transferred to production location c. FG assembled and send to storage location d. FG sent to fulfillment centers we have our demand and safety stock set on FG in FC locations, the goal is to eventually use MRP to transfer FG to FC, but for now we really want to make sure our production is handled based on demand. We would like to be able to say after this date we do not want to produce this item anymore, but if we just set demand to 0 then the transfers to FC locations will not run, but i think that is the answer, if something is being discontinued we set demand to 0 and we manually transfer final production. Does this make sense? I just want to know if there is some way to handle this in a more straightforward way like being able to turn off a SKU for production after a certain date. Even more ideally after consumption of its components
