Layout &1 is not consistent, you cannot continue

What causes this issue?

The layout &V1& is not consistent because it contains at least two entry
columns with different <DS:DE.BUKU_VALTYPE>BCS value types</> (budget
and release). However, you cannot simultaneously work with only budgeted
<ZK>and </>released budget data. This can only be done in separate
budgeting phases.
For further information, see the documentation
<DS:SIMG.FMBCS_RELEASE_BUDGET>Overview of Release Scenarios</>
