An import reports a few rejected rows, so you upload the entire file again. The second attempt may solve the missing rows while duplicating the ones that already succeeded.
Before reimporting, establish what the first attempt actually changed. Repeating the upload is not a neutral action.
Count accepted and rejected records
Suppose a file contains 84 rows. The first import accepts 80 and rejects four. A safe next step begins with identifying those four and understanding why they failed.
Uploading all 84 again may create duplicates unless the current product has a verified way to recognize or replace previously imported records. Do not assume that behavior exists.
Retain the import result and the exact file version used. A renamed file does not necessarily represent a different set of transactions.
Check overlapping periods
Monthly statements, rolling exports and manually entered activity can overlap. A July export generated on August 3 may include early August transactions that later appear in the August file.
Compare date ranges and stable references where available. Merchant, amount, account and posting date can help, but no single field is always sufficient.
Two genuine purchases can share an amount and date. A pending item and its final settlement can differ. Duplicate review needs context, not only a simple equality test.
Correct the extra event rather than inventing an offset
If a payment of 75 appears twice, adding 75 of fake income would restore the cash total while leaving both income and spending overstated.
Use the appropriate correction or reversal process to remove the duplicate economic effect. Retain a brief explanation, especially when the change affects an earlier period or shared export.
Do not delete a whole batch without checking whether it contains genuine records that are not duplicated elsewhere.
Reconcile after the repair
For a simple account with opening cash of 2,000, inflows of 3,000 and outflows of 2,400, the expected closing balance is 2,600.
Compare that result with the statement, then inspect important classifications and transfer pairs. A matching balance is necessary, but it does not prove that ownership and spending categories are correct.
Financeia's current journal guidance should be consulted for the supported import and correction workflow. Public descriptions alone do not establish automatic deduplication, batch rollback or a particular audit-trail behavior. Financeia
The best reimport process leaves a clear record of what was accepted, what was corrected and why. That prevents one failed upload from becoming a permanent uncertainty in the financial history.
