What's the best method to store Netsuite Product ID in Shopify's Admin menu?

[Usama788]

Hey, hope you are doing well.

I am getting products from Netsuite and then adding them at Shopify using Product API. For syncing data between Netsuite and Shopify we have to save Netsuite Product Internal ID at Shopify. So what is the best way of storing that ID at Product Admin menu i.e via using Metafields or something else and if using Metafields then which method to follow for that. I am waiting for your response.
Regards
