MRP across sites

Hi all,
I have two sites.
Sales order in site A with site B selected on the release. Release is marked as ‘Make’.
Run MRP (Approved revision with MOM) but the system does not create an unfirm job in site B.
Part plant for site B has ‘Process MRP’ checked.
If I use the order job wizard it creates the job in the correct site.
I am assuming that MRP should be creating an unfirm job in site B?
Any help would be welcome.
Thanks
Andy

Hi Andy,

I’m a little confused what you mean by “sales order in site A with site B selected on the release”.

So… is the part setup as manufactured on part plant tab in site B and is part revision / method setup for site B (not an alternate method, but primary method)? Is the plant on the sales order release set to satisfy demand from site B?

Hi Nancy,
The ‘Site’ dropdown has site B selected. Or ‘Plant’ if you prefer :slight_smile:
The part is set as purchase with an alternative method for site B.
Thanks
Andy

Hi Andy,

MRP will not do alt method automatically. Anytime you want to make the part different than the primary setup, you need to manually make adjustments.
If you had part setup as Mfd, plant B, with primary method making it in B and process MRP checked, you should get a job to make it in B.

Hi Nancy,
Thanks for your help. A bit frustrating.
I cannot set the type to manufactured as we mainly purchase the part. We use jobs to control the validation of equipment before it is shipped. So, not actually manufacturing from MOMs.

Do you have the “Primary Alternate Method” selected for Plant B? Is that alternate method designed for Plant B with Plant B Resources?

Hi.
I was just looking at the primary option.

I will try that.

Thanks

Andy

The PRIMARY option is a way to tell MRP to use the Primary alternate instead of the base rev… this also allows you to create a Revision, and have multiple alternates, and tell MRP WHICH alternate to use. We also used to use this as a trick when you had something as Purchased, but also had a BOM, you could set the primary alternate for costing purposes as well.

Hi Tim,
I am back to looking at this.
I am not getting any unfirm jobs in the plant selected on the sales order release. I am not even getting a new suggestion in the planning workbench.
Is this the way that the system works? Surely if you place demand on another plant they would receive some sort of prompt.
Any help would be appreciated.
Thanks
Andy

Agreed… if you enter an order across multiple sites (plants) then MRP should be picking them up and creating jobs.

  1. do the other sites have a Method of manufacturing (or an ALTERNATE method) for that site? Methods of manufacturing are site specific.
  2. are you actually running MRP in the other sites? (Obvious question… sorry, i had to ask). Remember that MRP is site specific.

Tim, can you clear something up for me? I think I’ve almost got it.

I want to quote something in site B that is manufactured in site A. I’ve already discovered that I can’t run Get Details on the quote unless I have an alternate MoM in site B. When the quote is turned into a sales order, OrderRel.Plant defaults to site B. Would setting a primary alternate influence OrderRel.Plant? In which site should I set it, and/or where should I run MRP to get the job to appear in site A?

“It depends” on whether you have the system setup to get details from the quote. The problem is that if you used an alternate method in the quote that pointed to site B, the system will (and must?) assume that you really wanted to make it in site B. It has no way of knowing that you were not trying to override any defaults.
I would suggest that when you convert it to a sales order, that you would also force the Order release to be the correct site. I KNOW… the sales person may not fully understand that needs to be done. I think that the mistake is that you “needed” to get details in site B (to calculate costs & prices?). maybe the way to go is to have a secondary quote in site A that is a throwaway quote to do the costs/prices?.

Yes, I’m getting details in site B (a retail store) so a product configurator has a MoM to operate on. Price can then be quoted from the modified MoM. The job gets its details from the quote.

I’m trying to do it all with a minimum of customization. I might end up writing a BPM to default OrderRel.Plant to the site with the non-alternate MoM.

my cases also similar , i Have 2 sites site A all the SO and shipment , inventory.
in site B only production activities happing , while running MRP SO sub assembly part not creating and unfirm job suggestions , can any advice to check right setup or cross site suggestions will work in Epicor ?
