To access your payment method mappings, go to Setup > Customization > Record Types > Magento PL CG Mapping > List (or View Records).
This mapping is used in the Item Export (tier pricing sync) to map NetSuite price levels to Magento customer groups. By default, the mapping is empty. To add a new mapping, you need to fill in the NetSuite Price Level Id and Magento Customer Group Id columns. Optionally, you can populate the NetSuite Price Level Name column and the Magento Customer Name columns. To get the internal ids necessary to populate the NetSuite Price Level Id values, go to Setup > Account > Accounting Lists > Price Level. Please click here if Internal Ids are not displayed in your account.
To get the IDs necessary to fill in the Magento Customer Group Id values, in Magento, go to Customers > Customer Groups, and then use the ID column in the list.
When mapping new entries or changing existing ones, please be sure to refresh integration caches when you are finished.
