Why the user can still access all data after applying section access restriction?

[SissiChen415]

Hi, all.

Question:

• I want to restrict users to the data only under their corresponding departments. But all the users can still have all the access even after applying the session access restriction below.
• The wield thing is it worked a few moth ago with the same code and data.  But no matter how many times I tried now, I can't restrict the data access to users any more.
• Please help me figure this out if you encountered same issue or similar issue before. 

Session Access Code:

section access;
LOAD * inline [
ACCESS, USERID,REDUCTION
USER,MZHAO,FINANCE
USER,ECHAO,SALES
];

section application;
T1:
LOAD
Key,
Upper(Department) AS REDUCTION

(ooxml, embedded labels, table is Sheet1);

TestData Sample:

Key	Department	Month	Volume
1	Finance	Jan-20	10
2	Finance	Feb-20	15
3	Finance	Mar-20	22
4	Finance	Apr-20	30
5	Sales	Jan-20	18
6	Sales	Feb-20	23
7	Sales	Mar-20	19
8	Sales	Apr-20	61
