ISO Unit in SAP
Definition of ISO Unit in SAP
SAP uses internal units for measurement. To communicate with external systems, these internal units must be converted into the Electronic Data Interchange (EDI) standard.
ISO codes exist for standard measurement units, and are used for data exchange via EDI with external systems. To implement communication with external systems, ISO codes must be assigned to SAP internal units. (source)

If an ISO code assigned to multiple currencies in SAP ERP, verify in SAP E-Sourcing that the ISO code is assigned to the same currency that is identified as the primary currency in SAP ERP.

- Log on to SAP E-Sourcing as the enterprise user. On the Master Data tab, choose Unit of Measure. For each relevant unit of measure, verify that the ISO code is the same as in SAP ERP. If an ISO code assigned to multiple units of measure, then verify that the default unit of measure for the ISO code is the same as the primary unit of measure in SAP ERP.
- In Customizing for SAP NetWeaver> , go to the details screen for each country involved in ALE distribution then verify the ISO code.
