Si Chen commented on OFBIZ-1242: -------------------------------- #1 I think if you want to use some measure of how long a product takes to ship, you should be using SupplierProduct not the ProductFacility entity. #2 Then shouldn't the "isLate" flag be set? It seems always to be set to "false" > MRP days to ship and inventory event planned dates issues > --------------------------------------------------------- > > Key: OFBIZ-1242 > URL: https://issues.apache.org/jira/browse/OFBIZ-1242 > Project: OFBiz > Issue Type: Bug > Reporter: Si Chen > > I noticed a couple of interesting issues with the MRP algorithm: > It was using ProductFacility.daysToShip to create a buffer time for > requirements, but it was doing it for all requirements, so even manufactured > parts were having this buffer time added. I fixed it in 575413 by limiting > days to ship to only sales order related requirements. However, I believe > that daysToShip should be eliminated altogether in MRP, because I think this > field should be used as an average value for customer-related "how long it > takes to ship this order." The actual time to manufacture or order and > receive an item may vary, depend on the priority of the order, etc. If a > buffer process is required, it should be added for example as a manufacturing > routing task. > The other issue is that MRP will create inventory events in the past (ie, > before the time when it's run.) I think we should limit it so that inventory > events created should be now or in the future. > If there are no comments to the contrary I will make these changes and commit > them. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
