Remove Anomaly step by step : blo helpdesk

 Logical discrepancy (anomaly) in the voter data.

 🔴 What it means:

👉 The system is saying:

> Two voters linked to the **same parent** have an **age gap of less than 9 months**.

 🤔 Why this is flagged:

Normally, two children from the same parents should have **at least ~9 months difference (biological gap).

If the gap is less than that, the system suspects:

 ❌ Duplicate entry

 ❌ Wrong DOB (Date of Birth)

 ❌ Wrong parent linkage

*❌ Data entry mistake during SIR

 ✅ What you should do (as BLO):

1. Verify both voters physically

   Check DOB from documents (Aadhar, Birth Certificate, School record)

2. Check family details

    Are they actually siblings?

   Or wrongly linked to same parent?

3. Correct the issue

    If DOB is wrong → update it

    If parent mapping is wrong → correct family linkage

   * If duplicate → mark/delete as per process

4. Use appropriate form

    ✍️ Form 8 (for correction)

    ✍️ Form 7 (for deletion, if duplicate)

 ⚠️ Important:

 Sometimes **twins** can also trigger this (valid case ✔️)

But twins will have **same DOB**, not a random <9 month gap

 💡 Simple example:

* Person A DOB: Jan 2000

* Person B DOB: Aug 2000

  👉 Gap = 7 months ❌ → anomaly
