What causes this issue?

No (ISO) unit of measure was determined in the item. Entries for the

System Response

The item cannot be correctly processed without the unit of measure.

How to fix this error?

You can specify the unit of measure using the function "Process Errors".
However, the following must be observed:
Missing entries on the unit of measure is an error that has to be
eliminated. Either your customer does not transfer units of measure
correctly, or there are incorrect settings when transferring data from
the EDI subsystem to the SAP IDoc interface (mapping).
If you specify a unit of measure with the function "Process Errors",
this has to be a valid ISO unit of measure (for example "PCE"). Here,
you must ensure that this is an example of the correct unit of measure,
and that it is used for this material as either a base or a sales unit.

  The SAP error message VSB261 "No unit of measure in transmitted item" typically occurs in the context of sales and distribution (SD) or materials management (MM) when a transaction is processed that requires a unit of measure (UoM) but none is provided for a specific item. This can happen during various processes, such as sales order creation, delivery, or invoice processing.
  Cause:
  
  Missing Unit of Measure: The most common cause is that the item in question does not have a unit of measure defined in the material master or in the sales order.

  Data Entry Error: During manual entry, the user may have forgotten to specify the unit of measure for the item.
  Integration Issues: If the data is being transmitted from another system (like an external ERP), there may be issues with the data mapping or transmission that result in missing UoM information.
  
  Solution:
  
  
  Check Material Master:
