Handling Unit of Measurements in Data Migration cockpit.

[Prasobh]

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.

You may see unit of measurement in most of our migration objects and in the mapping step, the same needs to map to a target ISO code. The unit of measure needs to be mapped to a valid ISO code. Nevertheless, you may not see certain ISO codes or Unit of measurements appear in the search help of the mapping step of the migration process. Let us learn more about it through a practical use case.

Where is the Unit of Measurement configured and how it can be linked with an ISO code?

For SAP S/4HANA Cloud Public Edition, you can configure the same in below SSCUI.

For SAP S/4HANA Cloud Private Edition, you can configure the same through CUNI transaction. You can find the details in T006I (all valid ISO codes) and T006 (linkage between UOM and ISO codes) tables,

Let us try to map Unit ‘H’ as shown in below configuration to the mapping step of the migration in one of the values.

Below is the mapping step in the migrate your data. Let’s go inside the mapping step.

Source value provide in the template/staging is “Hours” as shown below and need to map the target value to ‘H’ as shown in the above configuration.

But when search for the ISO code ‘H’ in the search help, the entry is not listed. It would be the same result even if you search with Internal SAP code or any.

Let’s revisit the configuration of the UOM in the SSCUI – 102179 in detail. As shown below, there is no ISO code assigned and the Primary code is not marked. Internal UoM should be mapped to a valid ISO code and the primary code should be checked.

Let’s create a new ISO code in the same SSCUI configuration. Go inside the ISO codes option below.

Create ISO code H_1 for this purpose as shown below.

Link the new ISO code H_1 for the unit ‘H’ and checked the Primary flag as shown below.

You can now find the ISO code in the Data migration mapping step as shown below.
