Two potential solutions to this issue are to use b2b data enrichment tools or a JOIN operation to rejoin the grouped data with the original table, using a common key or set of keys. This will allow you to bring in all the missing fields that you need.

For example, let's say that you grouped your data by a field called "customer_id", and you only used the fields "customer_id", "product_id", and "order_date" in your grouping. You can then join this grouped data back to the original table using the "customer_id" field as the common key, and bring in all the missing fields that you need.

Here is an example SQL query that you can use:

SELECT *
FROM original_table
JOIN (
SELECT customer_id, MAX(order_date) as max_order_date, COUNT(*) as order_count
FROM original_table
WHERE <your WHERE condition here>
GROUP BY customer_id
) grouped_data
ON original_table.customer_id = grouped_data.customer_id
AND original_table.order_date = grouped_data.max_order_date

In this example, we are joining the original table with the grouped data using the "customer_id" field as the common key. We are also using the "MAX" and "COUNT" aggregation functions to determine some flags and KPIs in the grouped data.

By using a JOIN operation like this, you should be able to bring in all the missing fields that you need from the original table.

I hope this helps! Let me know if you have any further questions.
