SAP B1 Troubleshooting – Only a production or template BOM can be defined as a purchase item, ‘ITEM A00006’ [Msg 3566-4]

How to Resolve the Only a Production BOM or a Template BOM can be Defined as a Purchase Item Error in SAP B1

Error Description:

When creating a sales or assembly Bill of Materials (BOM), users may encounter the following error message: “Only a production BOM or a template BOM can be defined as a purchase item [Product Tree Parent Item], ‘ITEM A00006’ [Message 3566-4].” This error can prevent the smooth creation of the BOM, disrupting your workflow.

Symptom:

While attempting to create a Sales BOM, the system throws the error mentioned above. Below is a snapshot of how the error might appear:

Root Cause: This issue typically occurs when the item defined in the BOM header is set as an inventory item. In SAP Business One, a sales item must be used in the BOM header rather than an inventory or purchase item. The system only allows production or template BOMs to be defined as a purchase item (Product Tree Parent Item), hence causing this error.

Solution:

To resolve this issue, follow these steps:

• Open the Item Master Data: Go to the Item Master Data for the parent item in the BOM (e.g., ‘ITEM A00006’).

• Modify the Item Settings:

1. Untick the “Inventory Item” and “Purchase Item” options.
2. Ensure the “Sales Item” box is checked

• Save and Update: After making these changes, click the “Golden Arrow” for the parent item in the BOM header to update the item.

• Recreate the BOM: Once the item master data has been updated, proceed to add the BOM again. The BOM will now post successfully without any errors.

By ensuring that the parent item in the BOM header is correctly set as a sales item (and not as an inventory or purchase item), this error can be easily resolved, allowing you to continue creating your BOMs without any interruptions.

SAP B1 Error: “Only a Production or Template BOM” – FAQs

1. What does the error “Only a production or template BOM can be defined as a purchase item, ‘ITEM A00006’ [Msg 3566-4]” mean in SAP Business One?

This error occurs when you’re trying to define a non-production BOM (e.g., a sales or assembly BOM) with an inventory item as the parent item. SAP Business One only allows production or template BOMs to use inventory items as parent items.

2. How do I resolve the “Only a production or template BOM” error in SAP Business One?

To resolve this issue, navigate to the Item Master Data for the parent item in the BOM. Untick the “Inventory Item” and “Purchase Item” options and ensure the “Sales Item” option is selected. This will enable the creation of a valid BOM.

3. What is the significance of a parent item in a BOM?

The parent item in a BOM represents the main product or assembly you are creating. In the case of sales BOMs, the parent item should be defined as a sales item, not as an inventory or purchase item.

4. Can I use any item type as the parent in a BOM?

No, only certain item types are allowed in BOM headers. For sales BOMs, the parent item must be set as a “Sales Item.” Inventory and purchase items cannot be used as parents for sales or assembly BOMs.

5. Why does SAP Business One allow only production or template BOMs to have a purchase item as a parent?

Production and template BOMs are typically used for manufacturing processes, where raw materials are purchased and then assembled into finished goods. Therefore, SAP Business One allows the use of purchase items in these specific BOM types to facilitate the procurement and production workflows.

6. What happens if I don’t update the item master data correctly?

If you don’t update the item master data correctly, you will continue to face the error message and won’t be able to create or update your BOMs. It’s crucial to ensure the correct item type (Sales Item) is selected for the parent item in your BOM header.

7. Can I fix this error without modifying the Item Master Data?

No, the error stems from incorrect settings in the Item Master Data for the parent item. Modifying the item settings is essential to resolving the issue and allowing the BOM to be created or updated correctly.

8. Can I modify the parent item settings in an existing BOM?

Yes, you can modify the settings of an existing BOM by updating the Item Master Data for the parent item. After making the necessary changes (unticking “Inventory Item” and “Purchase Item” while ticking “Sales Item”), you should be able to proceed with the BOM.

9. Why is it important to untick the “Purchase Item” option in the Item Master Data?

Unticking the “Purchase Item” option ensures that the parent item is defined as a sales item rather than a purchase item. This is necessary to comply with SAP Business One’s restriction on BOMs, where only production or template BOMs can have purchase items as the parent.

10. Is there any impact on existing inventory data when I update the Item Master Data to resolve this error?

No, updating the item settings to resolve this error (e.g., unticking “Inventory Item” and “Purchase Item”) will not affect existing inventory data. However, it’s essential to ensure you have the correct item type set for each product in your inventory to avoid future errors.
