# BC Friday Tips #69 Item Blocked Fields

[Read the post](https://thatnavguy.com/blog/2026/bc-friday-tips-69-item-blocked-fields/) · That NAV Guy (Teddy Herryanto, MVP) · 2026-04-10 · 109 words · tier community · reviewed (checked by Opus)

> The Item table in Business Central has multiple blocked fields (Blocked, Sales Blocked, Purchasing Blocked, Service Blocked) that control item restrictions. Checking only the main Blocked field can miss module-specific restrictions and cause logic errors.

## Key points

- Item table contains multiple separate blocked fields for different modules
- Checking only the generic Blocked field can allow restricted actions like sales on sales-blocked items
- Item Variant and other tables also have multiple blocked fields
- Developers should validate against all relevant blocked fields based on context
- Ignoring module-specific fields creates bugs that only appear in certain scenarios

## Quotes

- "If your code only checks the Blocked field, your logic can break." (Highlights the critical risk of incomplete validation that leads to unintended behavior)
- "You may allow actions that should be restricted, such as sales on items that are blocked for sales." (Demonstrates the specific consequence of ignoring module-specific blocked fields)

## AL objects mentioned

- [table 5401 "Item Variant"](../../objects/table/5401.md)
