Calculation
Calculations are defined in the cases where the value of a message field needs to be converted from one unit to another. To define a calculation mapping the Function type needs to be set to "Numeric functions" and the function needs to be set to "calculation". The attributes that need to be set in a calculation mapping are:
| Attribute | Required | Description |
|---|---|---|
| From | Y | Defines the field name before mapping. |
| To | Y | Defines the field name after mapping. |
| Precedence | N | Defines the precedence used when mapping. |
| Function type | Y | Defines the type of mapping. Needs to be "Numeric functions". |
| Function | Y | Defines the mapping type. Needs to be "calculation" |
| Calculation | Y | Defines the operator. |
| Factor | Y | Defines the second operator (the first one being the field value). |
- Add: field_value + factor
- Complement: field_value - factor
- Divide: field_value / factor
- Multiply: field_value * factor
- Reciprocal: factor / field_value
For example, if there is an incoming message with the value in Gigabytes and another product needs the value to be in Megabytes, a calculation is needed.
