Batch discrepancies help you ensure that all the information shared between Growth Method and your ChMS matches and is correct.
A batch discrepancy is when you need to manually verify what to do with a user's submitted information in Growth Method. Batch discrepancies are typically due to a conflict in your ChMS where it's unclear that the people match in Growth Method. For example, John Doe submits a form listing his email address as email@example.com, but you already have a John Doe whose email address is firstname.lastname@example.org. This would produce a batch discrepancy.
You should resolve any batch discrepancies to ensure that all the information loaded from Growth Method into your ChMS is updated and accurate.
