• Message type: E = Error

• Message class: FDT_EXPRESSIONS - Formula & Derivation Tool: Expressions

• Message number: 649

• Message text: Quantities with different units cannot be transferred

What causes this issue?

During data transfer between BRFplus and the calling application, the
system has determined the following problem:
The system tries to transfer data stored in structure data object &v1&.
The structure contains at least two quantity fields, and the units of
measure are not identical in all fields. At the same time, the
corresponding data structure of the calling application contains only
one reference field for the unit of measure. Therefore, transferring a
record which contains different units of measure at the same time
between the two structures is not possible.
Note: The problem was determined in structure &v1& at field &v2&.

System Response

The system raises an exception.
