Migrating VC -> AVC transparent variant table

Hi,

We want to migrate production models from ERP to S/4 public cloud.

We are facing an issue when we want to define a variant table pointing to mara to retreive some field values. We have no clues on how define it or read MARA table directly in AVC.

I have seen that it can support CBO but we do not want to duplicate data.

Does some of you have any clues ?
