How To Fix AQV894 - Blank unit field found

SAP Error Message - Details

• Message type: E = Error

• Message class: AQV - Message texts for SAP Query

• Message number: 894

• Message text: Blank unit field found

What causes this issue?

Currency fields and quantity fields belong to the data read in your
query. Each currency field and each quantity field has a reference
field (currency key field or units field) containing the corresponding
currency or unit. When reading a currency field or a quantity field,
the system found that the corresponding units field does not contain a
value (SPACE). This implies that the reference fields were not
correctly defined in the functional area for which the query was
created.
If the reference fields are not defined, the query cannot distinguish
quantities with different currencies or units and therefore might not
perform summations correctly.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the corresponding functional area. This error should not occur
for functional areas using logical databases because the corresponding
database program makes sure that the reference fields always have the
right value.
For functional areas that do not work with logical databases, you might
have to use the coding for record processing to ensure that the
reference fields of the selected currency and quantity fields are
assigned the correct values.
