Subcontracting : How can we use purchase lead time instead of route calculated time?

Posted on by Omario

Hi dear community,

In a context of subcontracted work where I don't need to schedule the operation internally.

I need to have the following scenario : once I estimate the Production order, Subcontracting purchase order is created automatically and make sure that receipt date of the PO follow the item lead time regardless of the ordered quantity.

I'm currently facing the following issue: once I release the production order, the receipt date = end date of the production order which is not the required behavior.

Thanks for your help.

best regards

Hy,

I assume you have the "route type" set to Vendor and added the item to purchase.

How the Oper No set? Are there any operations after that ext. Vendor work?

Pls share more details.

HI,

Its a Route with a unique subcontracted operation.

And yes Route and resource type and BOM line type are set to vendor.

I want to make sure that delivery date on the subcontracted purchase order take into account lead time of the purchased item (default order setting) regardless of the route times and produced quantity.

Thanks in advance.

How are you creating your production order? It sounds like your coverage group for the service item is either manual (and thus PO only creates during estimation of the production order and not during master planning) or you are manually creating the production order, then estimating. If you instead let the planning engine create your production orders and your directly derived subcontract PO's, you'll get a PO that respects lead time of the service item.

Hello OA,

Have you already tried to setup a purchase trade agreement? In purchase trade agreement you can add the supplier, item and leadtime.

Make also sure that you activate the paramer 'Find trade agreements' of the Master Planning parameters.

Best regards,

Hi Omario

Did you get this to work? I have the same situation.

I tried the suggestions from the other users but it still does not work.

I created a purchase price agreement on the service item with a lead-time of 14 days, combined with a queue before = 7 days (168 hours) on my vendor route operation. This is to see which one the system will use.

The production order is created manually and scheduled manually. The system still uses the queue before time in the planning.

However, the requested receipt date of the purchase order line for the service item is actually at the end of the queue before time. I guess I need to setup the queue before time to match the lead-time on the trade agreement? The system seems to discard the lead-time on the service item.
