BOM transformer automatically generates multiple copies of existing standardized manufacturing part

Hello,

We recently started to encounter a problem with multiple entries of the same manufacturing part/assembly being automatically added/generated when using the BOM transformer.

A large part of our sub assemblies and parts are standardized and also have linked standardized manufacturing parts. This means that when we create an MBOM from an EBOM which in it’s assembly structure contains some of these standardized sub-assemblies/parts the manufacturing version of these parts are automatically added inside the MBOM structure.

This in itself is desirable since it saves allot of time having to manually add or create these manufacturing versions every time. However lately we have found that when generating an MBOM multiple instances of the same manufacturing parts are added which have the exact same version, name and quantity.

The double entries can be removed manually but could potently lead to problems in orders if the person constructing the MBOM is not aware or paying enough attention.

Has anyone encountered a similar issue/or knows how to solve this? I have looked around on the PTC forums but could not find any similar posts.
