How to Fix “Specify a UoM Code” Error in SAP B1 Marketing Documents

As an SAP Business One(SAP B1) user, encountering errors during the creation of marketing documents is not uncommon. One such error is the “Cannot add or update document; specify a UoM code” message, which can arise during transactions involving sales orders, deliveries, or invoices. This blog post aims to walk you through the cause of this error and how to resolve it efficiently.

Error Description:

The error message, “Cannot add or update document; specify a UoM code”, typically appears when you try to add or update a marketing document but fail to specify a Unit of Measure (UoM) for one or more line items in the document. This issue can disrupt the process, preventing the document from being posted.

Symptom:

You will encounter this error when working on marketing documents (e.g., sales orders, invoices, deliveries) in SAP Business One. As soon as you attempt to save or update the document, the system prompts the error message, as shown below.

Cause:

This error occurs because the UoM code has not been provided for one or more line items in the document. The system requires a UoM code to correctly calculate and track quantities for inventory management and other transactional processes.

Solution:

To resolve this error, you need to specify a UoM code for each affected line item. Follow these simple steps:

1. Navigate to the affected marketing document (e.g., Sales Order, Delivery, or Invoice) where the error has occurred.
2. Identify the row(s) missing the UoM code. This can be done by checking the line item details.
3. Provide the correct UoM code in the UoM field for each relevant line item.
4. Save and post the document. Once you have entered the UoM code, you should be able to successfully save and post the document without encountering the error.

By ensuring that every line item in your marketing document has the appropriate UoM code, you can avoid this error and proceed with your transactions smoothly.

The “Cannot add or update document; specify a UoM code” error is a straightforward issue that can be resolved by simply entering a UoM code for each affected line in the document. Keeping track of UoM settings and ensuring they are correctly filled out in marketing documents can help prevent this issue from disrupting your work in SAP B1.
