Units are different - function will be performed w/o reference to units

Message type: E = Error

Message class: M5 - LIS: Standard Analyses (Inventory Controlling Doc. Analysis)

Message number: 021

Message text: Units are different - function will be performed w/o reference to units



What causes this issue?

The units of measure in the selected column(s) are not the same.
Subsequent processing will therefore takes place without reference to
units. This can produce misleading results if quantities of different
units are compared with each other.
