Hi Experts,

Hope everyone is doing well.

We have one client requirement where we have the IMEI number (which is a dff under the serial number) using that IMEI number we need to reverse track and find the Inventory Serial Number.

We have come across the below mentioned API but in this we need to pass the unique ID of the Serial Number. But in our case we dont have that information

/fscmRestApi/resources/11.13.18.05/inventoryItemSerialNumbers/{inventoryItemSerialNumbersUniqID}/child/serialAttributeDFF

Kindly let us know if anyone has done this similar requirement in any of your project.
