• Message class: CCMM - Message Class for A&D CCM

• Message number: 023

• Message text: Different quantities or units found. Quantity check is not possible.

What causes this issue?

Possible causes:
The pieces of equipment assigned to the<DS:DE.CCM_FUNCID>function iden
tifier</> have different materials. After comparison with the table that
contains the valid parts for the corresponding iPPE structure nodes,
these materials have different quantities or units.
You have allowed the (equipment) BOM mode in Customizing. The structure
gaps and (equipment) BOM items that belong to a function identifier have
different units of measure.
You have allowed the (equipment) BOM mode in Customizing. The structure
gaps and (equipment) BOM items that belong to a function identifier have
the same unit of measure but it does not match the unit of measure in
the iPPE structure nodes.

System Response

The system cannot execute a quantity check for the relevant materials.

How to fix this error?

Check if the table of valid parts for the corresponding iPPE structure
nodes has been set up correctly and run the quantity check manually.
If you have allowed the BOM mode, check the units of measure of the
structure gaps and BOM items. If you can correct the values, you can run
the quality check again. Otherwise you have to check the quantities
manually.
