Custom balance group showing data in application but not pulling in extract.

Summary:

We have used this dimension "Relationship Tax Unit, Reference Code Run " in LOAN 403B custom balance group.

The underlying element feed is Loan 403B Results. Please note that LOAN 403B has a deduction reference which gets stored in the element entry which we need as well. Hence this dimension has been used to pick that.

We used it in an HCM Extract (balance group extract) .This was working perfectly in our instance.

Suddenly we see that after a payroll run rollback, when the new run was done, our HCM Extract referring this custom balance group, is no longer pulling values.
