I don't see any values from the mapped table

[shilpan]

Hello,

I have a simply mapping table showing update root cause, but when I hover over the fact table, it is showing density 0%. I can't figure out why.

Map_Root_Cause:

LOAD Root_Cause__c,

     Updated_Root_Cause

FROM

(qvd);

Fact table:

ApplyMap('Map_Root_Cause',Root_Cause__c,'Unable to Validate') as  [Updated Root Cause]

Can you tell what am I doing wrong?

You have to do a mapping load

Map_Root_Cause:

MAPPING

LOAD Root_Cause__c,

     Updated_Root_Cause

FROM

(qvd);
