Standard cost estimate for future period &3 cannot be marked

What causes this issue?

In &v4&, the following occurred:
You are attempting to <DS:GLOS.mark>mark</> the standard cost estimate
for material &v1& in plant &v2& for the future posting period &v3&.
However, this standard cost estimate has the costing status KF (costed
with errors). This status does not allow marking.

How to fix this error?

First save a standard cost estimate for the future posting period &v3&
&v4& that has the status KA (costed without errors).
Then carry out marking again.
