fnd_global in Oracle Apps vs Oracle Fusion

Oracle EBS has fnd_global package, which sets global variables, in turn available to be access through custom plsql code, java code etc.
However in Oracle Fusion there is slight change, instead of fnd_global.user_name (refers to fnd_user table , user_name column), we need to use fnd_global.who_user_name (per_users table, username column)


FND_GLOBAL.USER_NAME  -> FND_GLOBAL.WHO_USER_NAME (per_users table, username column)
->(FND_GLOBAL.USER_GUID (per_users table, user_guid column)


You may run below sql in FUSION_FSCM, Data-Model- SQL based:

select * from all_source where name like 'FND_GLOBAL'
