# <CommissionDataGrp> component block

## FIX 5.0 SP2 EP299

### Description

 The CommissionDataGrp component block is used to carry commission information such as the type of commission and the rate. It provides an alternative to the CommissionData component if multiple commissions or enhanced attributes are needed.

 The [CommissionLegRefID <2649>](https://www.onixs.biz/fix-dictionary/5.0.sp2.ep299/tagNum_2649.html) field is used to reference the [LegID <1788>](https://www.onixs.biz/fix-dictionary/5.0.sp2.ep299/tagNum_1788.html) within the InstrumentLeg component, allowing for specifying instrument leg specific commission values when a multilegged security is fully expressed in the same message. This component is not intended for non-leg instances of the CommissionDataGrp component to represent aggregated values of the leg instances within the component when both leg and non-leg instances are included.
