Case Statements: Your Secret Weapon for Data Transformation

In the world of NetSuite saved searches and reporting, case statements are the unsung heroes of data transformation. These powerful tools allow you to evaluate conditions and transform raw data into meaningful business insights. Whether you’re normalizing data, translating codes, or performing complex calculations, case statements are your secret weapon.

What Are Case Statements?

Case statements in NetSuite function like sophisticated IF-THEN-ELSE logic, allowing you to:

Evaluate multiple conditions in sequence
Transform data based on specific criteria
Create calculated fields with complex logic
Standardize inconsistent data
Translate technical codes into business language

Real-World Applications

Let’s explore practical examples that demonstrate the power of case statements in action.

Example 1: Normalize Shipping Weight Units

Different systems often store weight in various units. This case statement standardizes all weights to a common unit:

CASE 
  WHEN {custbody_weight_unit} = 'KG' THEN {custbody_weight} * 2.20462
  WHEN {custbody_weight_unit} = 'LB' THEN {custbody_weight}
  WHEN {custbody_weight_unit} = 'OZ' THEN {custbody_weight} / 16
  WHEN {custbody_weight_unit} = 'G' THEN {custbody_weight} * 0.00220462
  ELSE {custbody_weight}
END

This transformation ensures consistent weight calculations across your entire system, regardless of the original unit of measurement.

Example 2: Decoding Error Codes

Technical error messages can be cryptic. This case statement translates them into business-friendly language:

CASE {custrecord_error_code}
  WHEN 'ERR_001' THEN 'LOT/Serial Issue'
  WHEN 'ERR_002' THEN 'Shipping Address Line 1 Issue'
  WHEN 'ERR_003' THEN 'Invalid Customer Reference'
  WHEN 'ERR_004' THEN 'Duplicate Order Detected'
  WHEN 'ERR_005' THEN 'Inventory Shortage'
  WHEN 'ERR_006' THEN 'Credit Limit Exceeded'
  WHEN 'ERR_007' THEN 'Tax Calculation Failed'
  WHEN 'ERR_008' THEN 'Invalid Payment Method'
  ELSE 'Unknown Error - Contact Support'
END

Now your customer service team can quickly understand and address issues without needing technical knowledge.

Example 3: Time Difference Analysis

This sophisticated case statement analyzes processing times and provides business insights:

CASE 
  WHEN {status} = 'Pending Fulfillment' AND 
       ROUND((SYSDATE - {trandate}) * 24) > 48 
  THEN 'Critical - Over 48 Hours'
  
  WHEN {status} = 'Pending Fulfillment' AND 
       ROUND((SYSDATE - {trandate}) * 24) > 24 
  THEN 'Warning - Over 24 Hours'
  
  WHEN {status} = 'Pending Fulfillment' AND 
       ROUND((SYSDATE - {trandate}) * 24) <= 24 
  THEN 'Normal Processing'
  
  WHEN {status} = 'Shipped' AND 
       ROUND(({custbody_ship_date} - {trandate}) * 24) <= 24 
  THEN 'Same Day Shipping'
  
  WHEN {status} = 'Shipped' AND 
       ROUND(({custbody_ship_date} - {trandate}) * 24) <= 48 
  THEN 'Next Day Shipping'
  
  ELSE 'Standard Shipping'
END

This provides instant visibility into order processing performance and helps identify bottlenecks.

Advanced Techniques

Nested Case Statements

For complex logic, you can nest case statements:

CASE 
  WHEN {customer.category} = 'VIP' THEN
    CASE 
      WHEN {amount} > 10000 THEN 'VIP Platinum'
      WHEN {amount} > 5000 THEN 'VIP Gold'
      ELSE 'VIP Silver'
    END
  WHEN {customer.category} = 'Regular' THEN
    CASE 
      WHEN {amount} > 5000 THEN 'Preferred'
      ELSE 'Standard'
    END
  ELSE 'New Customer'
END

Combining with Other Functions

Case statements work beautifully with other NetSuite functions:

CASE 
  WHEN {quantity} = 0 THEN 'Out of Stock'
  WHEN {quantity} < {custitem_reorder_point} THEN 
    'Reorder Needed - ' || TO_CHAR({quantity}) || ' remaining'
  WHEN {quantity} < ({custitem_reorder_point} * 2) THEN 
    'Low Stock Warning'
  ELSE 'In Stock'
END

Performance Optimization

Case statements can also improve search performance by pre-calculating complex values:

CASE 
  WHEN {type} = 'Sales Order' AND {status} = 'Pending Fulfillment' THEN 1
  WHEN {type} = 'Sales Order' AND {status} = 'Pending Billing' THEN 2
  WHEN {type} = 'Sales Order' AND {status} = 'Billed' THEN 3
  ELSE 0
END

This numeric result can be used for efficient sorting and grouping.

Best Practices

1. Order Matters

Place the most common conditions first for better performance:

CASE 
  WHEN {country} = 'US' THEN 'Domestic'  -- 80% of orders
  WHEN {country} = 'CA' THEN 'North America'  -- 15% of orders
  ELSE 'International'  -- 5% of orders
END

2. Always Include ELSE

Provide a default value to handle unexpected cases:

CASE {status}
  WHEN 'Open' THEN 'Active'
  WHEN 'Closed' THEN 'Complete'
  ELSE 'Unknown Status: ' || {status}  -- Helps identify new statuses
END

3. Keep It Readable

Use line breaks and indentation for complex logic:

CASE 
  WHEN {department} = 'Sales' AND {amount} > 10000 
       THEN 'Major Deal'
  WHEN {department} = 'Sales' AND {amount} > 1000 
       THEN 'Standard Sale'
  WHEN {department} = 'Support' AND {priority} = 'High' 
       THEN 'Urgent Support'
  ELSE 'Regular Transaction'
END

4. Document Complex Logic

Add comments in your saved search description explaining the business logic.
