1099 Reporting Vendor Tax ID change in a reporting year

Hello,

I am working for a client who has this unique situation. Here is the scenario:

Vendor A - Tax ID 123456789 1099 Reportable

Transactions > $600 happened in the current year until June.

Vendor B buys Vendor A in July and continue to do business. They have different tax ID 987654321

Transactions continue rest of the year totaling > $600.

We updated Vendor A Location in our Vendor Master with new effective dated row from July reflecting new tax ID.

I post withholding transactions. I see transactions in table PS_WTHD_TRXN_TBL reflecting both tax ID's based on transaction date.

However, when I run 1099 Report Job, my 1099 report is reflecting all amount under new tax id.
