Import master data via template

I have a batch of 1,200 vendor master updates provided by Procurement. Import the master data using the standard vendor template: VendorID, LegalName, TaxID, BankAccount, PaymentTerms, Currency, and CompanyCode. Validate for duplicate VendorID and missing TaxID, run the dry-run first and capture the error report, then execute the import during the maintenance window at 20:00 tonight. Notify Raj in procurement and Leena in compliance when complete and attach the import log.

Before I submit Procurement’s vendor file, make it approval-ready. Surface rows with missing TaxID, mismatched bank IBAN formats, and duplicate legal names; move frequently checked columns (VendorID, TaxID, BankAccount, PaymentTerms) to the left; and add a summary sheet counting new, updated and rejected rows. Provide a clear error list that matches the system import messages so Raj can fix the source file quickly.

I ran the vendor master dry-run and got 87 rejected rows with terse error codes. Procurement expects these in production tonight. I can’t tell whether rejects are due to format, duplicates, or business-rule validation like blocked tax IDs. I’m afraid to run the real import without causing partial updates. How should I triage the rejects rapidly, which checks to run manually now, and what safe steps let me proceed for the remaining clean rows this evening?

Master-data imports keep failing because Procurement and Finance hand off inconsistent templates and validations happen too late. I want a habit that stops churn: what one template change and two gates (when and who must sign off) would prevent late-cycle rejects and reduce our import failures by half? Make the solution simple for Raj, the data steward, and the scheduler running nightly jobs.
