Here’s a document I wrote about inventory classification. I hope you find it useful.
There’s a Simulate Multilevel Material Availability that is quite neat, but I think often forgotten about.
You can use IFS Demand Planning which will automatically create forecasts each week or month according to the parameters you decide and the historical consumption. The parameters are general and don’t need to be defined for each part individually. Then the forecasts can be used to calculate reorder points using our solution for inventory replenishment, or as input to the master schedule.
Sounds like you need to calculate the number of days remaining inventory and compare that with how many days remaining shelf life you have. We don’t have a standard report for this. All information is available in the system though, so hopefully you have a reporting tool you can use to create a report. If you are using IFS Demand Planning you will find the forecast in a view called forecast_day. The stock levels and expiry dates are in inventory_part_in_stock.
The only solution I can some up with is that you split the product structure and create a new sub-assembly level. This will of course complicate things as well, so maybe there are better options.
The process move handling unit do not have part number or the related GTIN (this is where you store the EAN) as data items. It means that it is not possible to give them as inputs. I think it makes sense since you can have multiple parts on a handling unit. To achieve what you are lookin for you could use the MOVE_PART process instead. I have tried and it seems to work nicely. You have to change the order of the data items so that you start with the handling unit id and then the GTIN. You need to turn use automatic value off to force the user to scan the GTIN number. It will now validate that your GTIN match with what you have on the handling unit. If not you get an error. Just remember to set the GTIN for your part to “Used for identification”. The main drawback I found with this approach is that since you are now moving parts, not handling units, the quantity refers to the quantity of the part on the HU. You can get this value automatically by configuring it this way, so it might not
By default requisitions are only created once the forecast pass the planning time fence (PTF). By default this is zero, but should usually be set to the cumulated lead-time for the part, in this case your lead-time from the supplier. There’s also an option to create requisitions along the entire forecast horizon, it is controlled by the value in the field “Create S/P req”. In this case the PTF doesn’t matter.
I agree with the above explanations. I order to detect potential shortages for B and C parts where you may have some exceptional demands, maybe an unexpected supply shortage or when supply exist but to late to meet actual demands, is to use the “inventory part availability exceptions”. This is a background job that will create alerts if for example your projected (future) inventory is going negative. Creating a lobby that displays a list of those parts with potential shortages goes a long way in my experience.
