Diagnosis
Currency fields and quantity fields belong to the data read in yourquery. Each currency field and each quantity field has a referencefield (currency key field or units field) containing the correspondingcurrency or unit. When reading a currency field or a quantity field,the system found that the corresponding units field does not contain avalue (SPACE). This implies that the reference fields were notcorrectly defined in the functional area for which the query wascreated.
If the reference fields are not defined, the query cannot distinguishquantities with different currencies or units and therefore might notperform summations correctly.

Procedure
Check the corresponding functional area. This error should not occurfor functional areas using logical databases because the correspondingdatabase program makes sure that the reference fields always have theright value.
For functional areas that do not work with logical databases, you mighthave to use the coding for record processing to ensure that thereference fields of the selected currency and quantity fields areassigned the correct values.
