Hi,

I have a part with four routing alternates, each of them using a Min Lot Size Based Qty and each of these alternates have an operation connected to a different Work Centre. The Phase In Date  for the routing and Validity Period are set to 25th July.

I ran the MRP and CRP and here’s the error message I get when trying to convert a Shop Order Requisitions into a Shop Order.

 


The Work Centre has capacity for that date-the total time for this shop order proposal would be less than an hour-.
What did I do wrong ?

​@Mbourret the system is trying to backward schedule the start date for the operation(s) based on the order due date of Aug 26. I’m guessing your new Work Center has only one resource, and this resource has a start date later than the calculated start date of the operation, so the resource does not exist on the date it is needed.

For your work center resource you should 1) delete the validity period as shown below and then 2) create a new validity period with a Start Date well in the past, e.g., 1/1/2020 with no End Date. This is  my standard recommendation when creating new Work Centers.

I’ve amended the dates, ran the CRP and still get the same error message. Any other thoughts ?Thanks

Provide a screenshot of the routing operation, showing the columns for Work Center, Mach Run Factor, and the Factor Unit.
