Interest rates missing: yield curve &1, currency &2, date &3

What causes this issue?

Interest rates are missing: yield curve &V1&, currency &V2&, date &V3&.
This may be due to the following:
No interest rates exist for any of the reference interest rate grid
points of the yield curve.
Although interest rates exist, they are older than the maximum age
defined for the yield curve in Customizing.
Interest rates for a specific validity date have been identified but not
for all the grid points indicated as mandatory for the yield curve in
Customizing.
