Hi Navinchandar Selvaraj,
As per there discussion
Yeah it is not a best practice to assigning SAP_ALL. You should create a new role with authorization. Please contact your basis team. Ask them to create a New role and grant Authorizations. But in some cases SAP recommended to assign SAP_ALL authorization. 
Hope this will help you out
Authorization Profile SAP_ALL - Identity Management - SAP Library
This composite profile contains all SAP authorizations, meaning that a user with this profile can perform all tasks in the SAP system. You should therefore not assign this authorization profile to any of your users. We recommend that you create only one user with this profile. You should keep the password of this user secret (store it in a safe) and only use it in emergencies (see also Protective Measures for SAP*).
Instead of using the SAP_ALL profile, you should distribute the authorizations it contains to the appropriate positions. For example, instead of assigning your system administrator (or superuser) the authorization SAP_ALL, assign him or her only those that apply to system administration, namely the S_* authorizations. These authorizations give him or her enough rights to administer the entire SAP system, without allowing him or her to perform tasks in other areas such as Personnel.
