Sorry for the confusion. Here is the details of the issue am facing.
Please consider the above table. The “last value“ is the last record mentioned for the "Product": "Bag" and "Product Code":"20", this was the only record available in AA and the other two records was not imported into AA. So if we are reporting by "Product" only the “Bag“ product and product code "20" is available for key “123”. There is no record for first 2 line items in the above table i.e. "Product" and "Product Code" that this "Key" is also part of "Books" and "Pen" product and "10" and "15" product code respectively.
I would like to see all the records in the table in AA, even though it have same key value.
@AAuser93 It's an expected behavior that the last uploaded classification value of any existing key-value will overwrite the previous value (provided the overwrite option is checked). Are you looking forward to have multiple classifications of the same key? Based on your data set, I believe you should consider the values in the column "Product" as the key and then further classify it as respective "Product Code".
