The “Incorrect Due Date for Bill” error during data splitting in Tally ERP 9 usually happens because of:
* Duplicate or overlapping bill numbers for the same party. * Bills with due dates that don't align properly within the financial period being split. * Data corruption or inconsistent ledger entries.
### Steps to fix the error and split data successfully:
1. **Backup Your Data First!** Always take a full backup before attempting any fix.
2. **Check Duplicate Bill Numbers**
* Go to the ledger of the concerned party. * Look for any bills with the same bill number (`RCW/019` or others) appearing more than once. * Rename or correct duplicates manually if possible.
3. **Verify Bill Due Dates**
* Open the bills and confirm that the due dates fall within the correct financial year. * Bills with due dates outside the split period may cause errors.
4. **Run Data Integrity Check**
* In Tally, go to **Gateway of Tally > F3: Cmp Info > Repair Company Data**. * Run the integrity check and fix errors reported.
5. **Correct Bill-wise Entries**
* Identify bills flagged as "Double Entry" or “wrong”. * Rectify these by checking vouchers and deleting or correcting entries as needed.
6. **Try Splitting Data Again** After cleaning data, attempt splitting again.
7. **If Problem Persists**
* Export the data to XML and re-import it into a new company folder. * Contact Tally support with error logs for deeper analysis.

**Pro Tip:** If urgent, you can also split the data using Tally’s **Split Data Utility**, but only after resolving inconsistencies.
