This tutorial demonstrates how to identify and resolve the **"Purchase Tax Details Not Found"** error that may occur while importing purchase vouchers from an external file in **Logic ERP**.
***
### Identifying When the Error Occurs
* Navigate to the **Main Menu** and expand **Utilities Module**.
* Again Expand **"Import Master/Transactions from External File".**
* Open **Import Purchase Voucher from External File** window.
* Click on **Browse**, select the file to import, and choose the appropriate **Excel sheet**.
* Click **Refresh**.
> If the "Invalid Doc" column shows "No", it means the data structure is correct at this stage.
* Enter the required details:
* **Account Name**
* **Supplier Name**
* **Godown Name**
* Click on **Save**.
> You will encounter an error:\
> \&#xNAN;**"Purchase tax details are not found for all items."**
***
### Understanding the Cause
This error can occur due to:
* Missing **GST column** in the Excel file.
* **Mismatch in GST Tax Group name** between Excel and Logic ERP.
* Duplicate or misspelled **Item Group** entries.
***
### **Verify and Correct Item Group Setup**
* Navigate to **Main Menu/Setup Item** and then expand **Setup Items**.
* Select **GST Tax Group** Click on **Level One**.
> Check for duplicate or misspelled group names (e.g., "GST Apparel" vs "Gst Apparel").
* **Deallocate** items from the incorrect/duplicate group.
* **Reassign** them to the correct group.
* Delete the duplicate group to prevent confusion in future imports.
***
### **Enable Pre-validation for Imports**
To prevent such issues during the import process:
* Go back to the **Purchase Import** window.
* Click on **Configuration**.
* Under **Document Detail Column**, locate the **"Map Only Column"** next to **Field Column**.
* Set the value to **True**.
* Click on **Save**.
> This will trigger early validation and detect inconsistencies before the actual import.
***
### **Validate Data Again**
* Reopen the **import file**.
* Select the correct sheet and click **Refresh**.
> If the "Invalid Doc" column now shows "Yes", proceed to investigate.
* Go to **Invalid Item Details** and scroll right to view the **Invalid Remarks**.
> Common issues:
>
> * Column names in Excel don’t match Logic field names.
> * Misspelled or missing tax group names.
***
### **Fix the Excel File**
* Open the Excel sheet.
* Correct the **Group Name** spelling or format to match Logic ERP exactly.
* Save the updated file.
***
### Re-Attempting the Import
* Return to the **Purchase Import** window.
* Browse and select the corrected file and sheet.
* Click on **Refresh**.
> Confirm that the "Invalid Doc" column now says "No".
* Enter:
* **Supplier Name**
* **Godown Name**
* Click **Save Bill**.
* Click **Yes** to confirm the import.
> The bill will be successfully imported.
***
### **Verify the Imported Bill**
* Navigate to the **Purchase Voucher** window.
* Search and **modify** the imported bill to verify the entries.
***
### **Need Help?**
If the issue still persists:
* Double-check group names and column headers.
* Use the **early validation feature** for every import.
* If needed, **raise a** [**Support ticket**](/logic-erp-installation-configuration-and-troubleshooting-solutions/troubleshooting/support-tickets.md) through Logic ERP.
