Does anyone knows what tables stores this information?

Summary:

Retrieving compensation informations

Content (required):

Under My Client Groups -> Elements -> Search Element Name I have this configuration for additional compensations:

One employee has this situation under his additional compensation and I'd like to retrieve the highlighted value for HCM Extract:

My HCM Extracts uses ELEMENT ENTRIES as User Entity and I'm able to get the amount of 9000 (same as previous image):

This values comes from this field defined in HCM Extract:

As mentioned I'm looking for the monthly payment amount but if I run the query used in user entity ELEMENT ENTRIES (with the same Extract_Employee_Payroll_Relationship_ID or Person_ID) I cannot find them in any of the tables it uses (not even the 9000 value!!).
