What is the limitation of importing custom records in place of transactions?

The limitation of importing custom records in place of transactions is primarily found in the option related to comparative reports. When custom records are used instead of standard transaction records, they may not be properly linked to the core financial systems and reporting functions within NetSuite. Consequently, reports that require historical data or comparative analytics could face limitations, particularly when examining data over a longer period.

Standard transactions are designed to feed directly into the financial reporting framework, offering a comprehensive view of a company's financial position. If custom records are used instead, it may take a significantly longer time for the data to accumulate and align with the standard reporting capabilities. Hence, comparative reports are likely to be limited until the data reaches a two-year threshold, as the system usually needs this time frame to begin forming reliable comparative analytics from the custom records.

This issue emphasizes the importance of using standard transaction types for better integration and reliability in financial reporting and the analytics framework within NetSuite.
