Hi @pjadhav21,
According to the release notes of SW32K3 BMS Application AUTOSAR 4.4_R21-11 0.8.0 D2402, you should follow "BMS_SWInstalationGuide_Application.pdf present in package manager". Can you confirm it was installed correctly?
Do you use updatesite.zip package in S32DS IDE, or did you install the standalone .exe version?
There are UM and IM documents:

Best regards,
Daniel
