why is the custom entity field not showing on ar aging report

AI generated answer (using internal Slack threads):

The custom entity field may not be showing on the AR Aging report due to several reasons: 1. NetSuite's native behavior: The AR Aging report in NetSuite is designed to only look for a Customer record and not a Vendor record. If you are creating a Journal Entry (JE) and tagging a Vendor to the line with an AP Account, it will show under the "No Customer" section. 2. Field settings: If you have created a custom field to display additional information (like a Customer's External ID), ensure that the field is set to store value. If the field is set to "Not store value", it will not be available on the report. 3. Account type: The ability to edit the Entity (line) details in a JE may depend on the account type you are selecting. If the account type is AR/AP, and the Entity (line) details are grayed out, it may prevent the custom field from showing on the report. 4. Saved Search limitations: If you are trying to recreate the AR Aging report using a saved search, be aware that it may not fully replicate the native report. For example, it may show the current AR, not the historical AR. If you filter it by a specific date, it will not show the open AR as of that date but the open AR as of today, including only the transactions until the specified date. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
