TB.One > Import & Export > Export Errors > How to Solve "Mandatory Value Missing"
Error description
This error message indicates that a required channel property (for example, "Material composition") is missing data. This happens, for example, when the component used in the value mapping is not attached to a product. Without this component, the property cannot be correctly assigned and TB.One cannot export the product data to the channel.
Solution
Verify that the required property and its value are completely filled in on the affected product or its articles.
Follow these steps to update your data and unlock the export of your product data from TB.One to the channel:
1. Check the Value Mapping for the Affected Channel
Open the value mapping for the channel where you encountered this error ("Channels > [Your channel] > Value mapping").
2. Locate the Affected Channel Property
Go to the global mapping (if available) or open the channel category to which your product is assigned. Identify the mandatory property causing the issue (middle column).
3. Identify the Assigned Component/Attribute
Check which component or attribute you have assigned to the mandatory channel property.
4. Verify the Component/Attribute Exists at the Product
Check the affected product to see whether the required component or attribute, and its value are present.
5. Add the Missing Component/Attribute
If the component/attribute is missing, add it to the product or its articles, including the appropriate value.
