Create order process not take Purchasing Lead time into consideration

The create order process will not create a requisition for a part unless the ‘required by’ date on an activity is showing as today’s date.

Purchase lead time: 10 days

 

Part has a preferred supplier (supplier for purchase part tab)

Supplier also has lead time’s setup  for manufacturing and inspection times

There are 180 in stock

But if i have a demand of 500 on an activity, reserve the 180 in stock and have the date set to the 14/11/23 (which matches the trigger for the purchasing lead time), it does not create a requisition when I use the Create Order Proposal background job.

When I change the ‘required by’ date in the activity tab to today’s date (01/11/23) it will create a requisition using the Create Order Proposal background job

 

 

Is there something else that would be overriding these values causing IFS to wait until the ‘required by’ date in the activity tab is the current day to order the materials?

 

Thanks

@AMcKevitt77 this behaviour happens because your Expected Lead Time = 1. This overrules the supp mfg leadtime and any inspection leadtime defined. You could run Calculate Purchase Lead time job to update the Expected Leadtime with what has been defined. In your case: 10 + 2

 

An excerpt from the documentation

Expected Lead Time

The expected lead time is the time, in days, that it takes to receive the parts into inventory assuming that not all component parts are in inventory. Therefore, the value in this field includes acquisition lead time as well as manufacturing lead time. For example, let's say that you manufacture a part consisting of several components and one of the components is not in inventory and must be ordered. In this example, the manufacturing lead time of the part is incorrect because it assumes that all parts are available from inventory. Thus, you should use the Expected Lead Time field to help ensure that a part can be delivered in time, even when not all components are in stock.

You can manually enter the lead time in the Expected Lead Time field. The expected lead time can also be calculated using the lead time calculations Calculate Purchase Lead Time found in IFS/Purchasing, and Cumulative Lead Time Calculation, Lead Time Calculation, and  Change Cumulative Lead Time  found in IFS/Manufacturing Standards.

The default value for the Expected Lead Time field is 0 (zero). If no expected lead time is entered in the inventory part record, the expected lead time is the same as the purchase or the manufacturing lead time.

@AMcKevitt77  delete the purchase requisition that was generated by the Order Proposal. Then, in the activity, set the ‘required by’ date to any date between today and the purchase lead time of the part, e.g., Nov. 5. Then run the Order Proposal again. You should get a purchase requisition again.

This is due to the demand driving the Projected Balance below the order point within the lead time of the part. When the demand was required on Nov 14, this matched the lead time so a requisition would not be generated until you ran the OP again tomorrow.

Hi both

 

Thank you for your answers, I shall ensure the Expected lead times are updated to match the purchasing lead times.
