Diagnosis
A basic formula for scale base value orcondition basis was called up duringgroup condition processing. As the items weregrouped for cumulation of the scale base value, multiple item groupsended up with the same condition type. In this case, the basic formulais not allowed.
This situation can occur when basic fomula '110 bulkiness (I)' is used,for example.

Procedure
In this situation, use a different basic formula('111 bulkiness (II)', for example) tocarry out the calculation. See also the corresponding procedure notesin the long text of the basic formula.
