Fetching Charges (Price) for standard items in OOTB CPQ-OM Integration package

Summary:

Fetching charges from Data table (created from OOTB CPQ-OM Integration package), is working for a model but not for Parts.

Content (required):

We enabled OOTB Integration b/w CPQ-OM. One of the key functionalities is to add charges for the items in Data table and via pricing engine it fetches. It works fine for a Model but not for a Part (std item).

Has any one faced this before?
