why I'm I receiving this error "The merge of the entity Vendor XXX was blocked for the following reasons: you cannot merge vendors with different tax IDs."?

AI generated answer (using internal Slack threads):

The error message you're receiving, "The merge of the entity <Vendor XXX> was blocked for the following reasons: you cannot merge vendors with different tax IDs.", is due to the fact that the two vendors you're trying to merge have different Tax IDs. In NetSuite, when merging two entities, it's important that they have the same Tax ID. This is because the Tax ID is a unique identifier for each vendor and is used for tax reporting purposes. If the two vendors have different Tax IDs, it would mean they are considered as separate entities for tax purposes and hence, cannot be merged. To resolve this issue, you would need to ensure that the two vendors have the same Tax ID before attempting to merge them. You can do this by going to the vendor record and updating the Tax ID field. Please note that you should only do this if you're sure that the two vendors are indeed the same entity and should have the same Tax ID. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
