The package will bring improvements to the DDA, GRC and RTC systems


As part of the continuous improvements of B3 Clearinghouse systems, we are launching a new improvement package. 

In this second 2022 delivery (click here to view the first improvement package) updates will be made to the GRC (Message) and DDA (Asset Distribution) systems, and a new version of the RTC (Real Time Clearing) system will be made available. 

For the GRC system, optional fields will be included in the messages of the asset buyback process, allowing users to request via message the execution of buy-ins restricted by the B3 Clearinghouse or undergoing exception treatment. 

In the DDA system, layout changes will be made on all screens.
