# RTE operation types included within the Integration Commons for CMDB app

The Robust Transform Engine \(RTE\) operation types are common operation methods for use in ETL without having to write your own complex data transformations.

The following operation types are available in the Integration Commons for CMDB app.

## Concatenation

Combines the values from input fields into a single string, joining them on the optional **joining\_string** field.

</table>## Multiple Input Script 

Runs a script with multiple inputs setting the **target\_sys\_rte\_eb\_field** field as the output for that script.

<table id="table_hty_g2d_jmb"><thead><tr><th colspan="2" align="center">

Details

</th></tr></thead><tbody><tr><td>

Table

</td><td>

RTE Entity Multiple Input Script Operation \[sys\_rte\_eb\_multi\_in\_script\_operation\]

</td></tr><tr><td>

Input field

</td><td>

**source\_sys\_rte\_eb\_fields** Input is a script.

</td></tr><tr><td>

Output field

</td><td>

**target\_sys\_rte\_eb\_field** Output is the result of the input script.

</td></tr><tr><td>

Additional Fields

</td><td>

-   **script** \(script\)
-   **use\_unique\_input\_sets**\(Boolean\): When `true`, only unique input values are included in the data batch for IRE processing. Otherwise, all input object’s field values are included.

</td></tr></tbody>
</table>Example for using **use\_unique\_input\_sets**, with a script function that takes `record_type` and `operating_system` as input and returns `record_with_os`:

|Record|record\_type|operating\_system|
|------|------------|-----------------|
|1|computer|Windows XP|
|2|computer|Linux|
|3|computer|Windows XP|

If use\_unique\_inputs\_sets is set to `true`, then the script processes only two values \(`computer` + `Windows XP` and `computer` + `Linux`\). If `use_unique_inputs_sets` is set to `false`, then each of the three values is individually processed \(`computer` + `Windows XP`, `computer` + `Linux`, and `computer` + `Windows XP`\).

Sample script:

```
(function(batch, output) { 
                for (var i = 0; i < batch.length; i++) { 
                        // batch[i] is the unique set of inputs/individual record 
                        // batch[i].<field> gives access to the field value 
                        var in0 = gs.nil(batch[i].record_type) ? '' : batch[i].record_type;
                        var in1 = gs.nil(batch[i].operating_system) ? '' : batch[i].operating_system;
                        // output[i] is the output for the specific combination of inputs/individual record 
                        output[i] = in0 + "_" + in1; 
                    } 
                } 
            })(batch, output);
```

## Multiple Input/Output Script

Runs a script with multiple inputs setting the target fields specified in the **target\_sys\_rte\_eb\_fields** field as the multiple outputs for that script.

                        var userIdParts = userId.split(".");

</table>The source field is included in the ‘batch’ variable as the JavaScript field ‘input’.

```

                for (var i = 0; i < batch.length; i++) { 
                        // batch[i] is the unique set of inputs/individual record

## Trim 

Removes any whitespaces at the beginning and at the end of the string included in the **source\_sys\_rte\_eb\_field** input value and assigns the result to the **target\_sys\_rte\_eb\_field** field.  This transform is equivalent to the Java String trim\(\) Method.
