Diagnosis
Possible causes:

• The pieces of equipment assigned to thefunction iden

tifier have different materials. After comparison with the table thatcontains 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 havedifferent 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 havethe same unit of measure but it does not match the unit of measure inthe iPPE structure nodes.

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

Procedure


• 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 runthe quality check again. Otherwise you have to check the quantitiesmanually.
