## How to Fix GST State Validation Error in GST Return?
In this tutorial, we will guide you through the process of **validating GST State details** while generating **GST returns** in Logic ERP.
***
### **Open GST Return Module**
* Navigate to the **GST Returns** module.
* Select **GSTR-1** as the return type.
* Choose the **relevant time period** for which you want to generate the return.
* Click the **Generate** button to proceed.
***
#### **Identify Invalid Data Error**
* Upon generation, if the system displays an **Invalid Data Error**, it indicates missing or incorrect details.
* In the **B2B section**, look for **red flags** beside certain entries — these mark records with invalid or incomplete information.
* The error message will state: **“Party GST State not specified.”**
***
#### **Review Error Details**
* Open the **GSTR Error Details** section to view a detailed list of invalid data entries.
* Here, you can see:
* The total number of **B2B invoices** with errors (e.g., 22 entries).
* Specific **error descriptions** such as missing or incorrect state names and codes.
***
#### **Correct Party State Details**
* Navigate to the Setup/Setup Accounts and Select **Setup New Account** module.
* Open each **relevant party account**.
* Verify and ensure that:
* **State Name** is correctly entered.
* **State Code** corresponds to the correct GST state.
* After verifying, **save** the details.
***
#### **Regenerate the Return**
* Return to the **GST Returns** module.
* Click **Generate** again to recreate the report.
* After corrections:
* The **Invalid Data Error** will no longer appear.
* In the **B2B section**, red flags will turn **green**, indicating that data is now **validated and error-free**.
* In the **GST Error Details**, the previous error count (e.g., 22) will now show **zero**.
***
#### **Export and Upload the Return**
Once the data is validated, you can proceed with filing your return through one of the following methods:
**Option 1: Create JSON File**
* Generate a **JSON file** and upload it directly to the **GST Portal**.
**Option 2: Export to Excel**
* Click the **Upload** button and select **Export to Excel**.
* The Excel file will be created for import into the **GST Offline Tool**.
***
#### **Upload via GST Offline Tool**
* Open the **GST Offline Tool** and choose **Import Excel**.
* Select the recently exported file and click **Yes** to import.
* The file will upload successfully, and a **summary** of the imported data will appear.
* Finally, click **Generate File** to upload and submit your return.
***
#### **Final Outcome**
You have now successfully:
* Validated the GST state details for all B2B entries.
* Resolved data errors.
* Exported and uploaded a **clean, validated GSTR-1 return** through the Logic ERP system.
