Alberta EE Serious Doubt : Pls help

[pradee2p2]

HI Guys ,

My Profile is as follows
Masters in Management Studies : ECA evaluated by IQAS

Work Ex : Total 8 Yrs 8 Months
Current NOC : 6222 : 4.5 Yrs ( Buyer) (Yr : 2019 )
NOC : 6552 : 1 Yr ( Buyer) :- Yr :2017
NOC : 0621 : 3.3 Yrs ( Retail & Whole Sale Trade Manager ) ( 2012 )

IELTS Score : ( LRWS) Band 7
Spouse : No Schooling / No ECA
CRS Score : 362
SINP Score : 61

NOC 0621 is an occupation in High Demand in Alberta under EE but its not my current Job NOC.

The point from below statement is very confusing "

You may receive a Notification of Interest letter if you:

• Are working in an occupation that supports Alberta’s economic development and diversification,

Does this means i should be currently working in the NOC Code which i have used as my primary occupation ?

If Yes then My Question is :-

Can i Change my NOC in Express Entry Profile from 6222 to 0621 for AINP ? I have reference letters for all of my work history



Pls guide
