SSCC Number range for HU

Issue- I am trying to generate a SSCC number for an HU. I have defined the settings at warehouse level, number range object /scwm/sscc, internal and external intervals etc. Maintained the number range for the internal interval as well. Now when i generate a new HU in /scwm/pack, i expect the HU to use the SSCC number range but its not doing it. Instead it is looking at the number range assigned to packaging material type which I am not maintaining hence it is failing. We do have some other warehouse in system where number ranges at pack material type are maintained. Cant figure out why system is not proposing a number from SSCC number range. Solution: I hope you have maintained the following set up in EWM.
