(8)Article 27h(1), point (f) of Regulation (EU) No 600/2014 requires CTPs to have systems in place that can effectively check the completeness of the data transmitted by data contributors, identify obvious errors, and request the re-submission of data. That requirement should entail the obligation for CTPs to flag potential data quality issues to data users and to communicate with data contributors to facilitate the resubmission of corrected trade reports. To ensure data quality, CTPs should put in place mechanisms to confirm to data contributors that they have received the input data. A CTP should not be required to confirm receipt in real time. In the event of serious data quality breaches, CTPs should be able to apply enforcement standards in a non-discriminatory manner. Enforcement measures that CTPs should be able to take include the suspension of revenue redistribution to data contributors and the notification of data quality issues to competent authorities. Additionally, CTPs should perform regular checks on the quality of output data, ensuring periodic reconciliation with the input data.
