Hi leyakoreya ,
Please note that the only addon not yet compatible with HPOS is ATUM Export Pro (only the part that has to do with WC Orders). All the other ATUM plugins are 100% compatible with HPOS, and, of course, we're working on adding compatibility with HPOS to that part of ATUM Export Pro.
As you may know, we don't provide support for custom coding. We offered you hiring externally the development agency behind ATUM, and that's what you did.
However, I asked them where they added the fields you're talking about, and following your specifications (adding
the fields for products with and without ATUM Multi-Inventory active):
- For products: they stored the fields in the postmeta table. Their keys are: 'cpnp_reference', 'cpnp_rp' and '_cpnp_address'. So you can access these fields in the standard WordPress way.
- For Inventories: they created the fields in the 'wp_atum_inventory_meta' table ('cpnp_reference', 'cpnp_rp' and 'cpnp_address').
FYI, we haven't released new versions of ATUM for a while because all our developers are focused on launching the ATUM App ASAP.
Best Regards,
José Andrés
