How to fix this error?

Background
For both reestimation and demand weighting you must uniquely select the
<ZH>leading installation</>, for which the register is to be
reestimated, or from which the demand values are taken for the demand
weighting.
For this to happen, the rate types for the register must be entered in
all additional installation allocations in the <ZH>rate types WITHOUT
reestimation</> table.
Recommendation
As a rule, a dummy rate type is sufficient for this purpose.
Additional Procedure
Check the rate types in all installation allocations for the register,
and change them so that one of the installations is the leading
installation.
