Hi,
We are in device manufacturing and need to add a couple of assets to a device while manufacturing. This assets behave quite similar to i.e. serial no.
but the assets are virtual and can come from a virtual pool. The particular use case will be:
A Device will be manufactured based on a BOM which contains:
* Raw Material Appliance (Board, CPU, Enclosure) This comes already with a serial number from the Appliance vendor which should be tracked for warranty
against the Supplier.
* Raw Material CPU
* Raw Material Memory
* Raw Material HDD/Flash
This device is going to be manufactured/assembled and becomes a new manufactured Item with our name and item code. The instance of this
item needs to get serial number which needs to be selected or generated. ist there a way to control how such serial number could be generated
based on i.e: Prefix/Suffix/ or even by assigning an "Implementation.py" for the logic of generation? Once the Device is finished it needs to be on stock.
Would be great to generate the barcode/QR Code for the serial number as well. We think most of this part is already available in ERPnext.
Further to the BOM above and the serial number a device receives a number of further "virtual" assets per item instance. When manufacturing the
device we need to add a couple of infos and artifacts while flashing the software onto the device i.e:
* A device ID based SSL Certificate
* 6 MAC Addreses for the LAN Interfaces
* a Software License String
* a SSH Key
* a device Specific WiFi PSK key
* a unique machineID which is be generated at first boot by the device
All this informations must be stored in the Item Instance Database. The Source of this informations is mostly virtual and would be based
on i.e.
* a implementation calling the SSL CA an generates a new Certificate
* a pre filled pool of MAC addresses where I select a number from
* a implementation of the calculation of the ned 6 free MAC addresses
* a implementation of the generation of a unique License ID
* a implementation of a unique PSK Key
* a implementation of a Call to a other system gives me the MaschineID by SerialNumber
Do you have any best practice how to approach this with ERPnext "plugins" or implementations? Should we consider these virtual assets as Virtual BOM
where the "manufacturing" of the "virtual raw material" is just handled by the Software Implementations mentioned above and generated just in time. Or do
you suggest to mimic the serial number function with more informations? We think having all this assets tracked is a major requirement mostly for service
and warranty, tracking but not really for selling, serial Number is enough for this. We don't ask for integrated this in the core but for the right extension points
and strategy.
best Regards,
Holger
