    We have just begun to attempt to implement MRP.  It appears that there are tons of different ways of doing this.  Just curious, do any of you have an tools (spreadsheets, surveys etc....) that your company used to decide which plans to use and how to configure them (along with items, coverage groups etc....)?  Perhaps there is an MRP implementation tool that we are not aware of?

    I would suggest everyone involved in the MRP process, learn and understand what and how item coverage's, coverage groups, lead times, and master plans settings that affect MRP behavior.  There is a series of 7 decent AXUG webinar recordings (Master Planning Unplugged) that can help you get started for both D365 and AX2012.  My company first learned the parameter settings and their function (Test Environment), then created basic coverage groups, ran MRP, then adjusted one or two parameters (baby steps) within a coverage group, then looked at "Net Requirements" to see the before and after, until we got our desired outcome.  I think you asking the AXUG community is a great start, as there are many knowledgeable AXUG users willing to help you through your journey.  Good luck!

    The process that Erick suggests is one that I typically suggest to clients as well.  Start with understanding the parameters and then move into setting up basic coverage groups and change one field at a time to get the full details of the changes.  There are also resources within AXUG that you can use and the webinar series Erick suggested is a great one.  If you have the desire and funding, I find that a one-day MRP boot-camp from your partner or another resource is also a great way to understand ​all the concepts related to MRP.  MRP is not just a "plug-and-play" tool within AXD365FO but requires analysis and understanding of how you want to see the output to really know what the parameter inputs should be set to.

    Thanks for the shameless plug on my MRP unplugged series! :) It is here in its entirety on AXUG.

    Hi Rich -

    My advice would be to bring in (or remote) a partner consultant for a day of training.  A day is the standard amount of time I budget when I instruct on MRP.  A follow up session a few weeks later would be a good idea as well.

    The MRP documentation for D365FO is contained in the "docs" site.


    The MRP documentation for AX2012 Rx CUxx is a PDF download.  I recommend this material even if you are on D365FO.  I've attached the PDF.

    I see you're in the apparel industry.  That can impact how your MRP is setup and run.

    I sent a message suggesting a good resource for training.

    You have had good input on this thread.  I would also offer this advice:  MRP configuration is a map of how your company "thinks"​ about planning.  Do you (really!) know your requirements?  Start with sitting down with the planning group and understanding categories of product, purchased and manufactured, what have been pain points they are trying solve with MRP, and a list of use cases.  It is a mini-implementation, and to be successful will need treated and documented much the same.  Then get the training, then spend time understanding the tool.  I usually set up a "dummy" item and BOM with no more than three levels as a learning tool.  Once you know how it works for a very simple item you have total control of, you can move to your more complex business situations.  Test over time: what happens when an order is late, for example?

    Last piece, because I could go on... don't outsmart yourselves initially. Start with simpler settings you really understand vs. trying to do really complex planning.  Example: start with negative and positive days set the same as your coverage period, so you don't get any result from them.  They are tough for users to understand, and can create more noise than help.   I would say it takes 12 or more months to optimize MRP once you go live.

    There will be good sessions at AXUG Summit, so I will plug that too!

    MRP is a black box engine so knowing parameters, inputs and expected outcomes is key to understanding it closely.
    DLP has some good reference.
    Also would suggest you a couple of new items, inventory transactions and with concepts and feature understanding tweak to see different results.
    e.g coverage group, positive days, negative days......etc

    MRP config and tuning is an art and needs to be optimize with changing needs,
