Why was only part of my transaction batch posted back to my CRM?

FlexPay processes batch files in slices. This means that a large batch is subdivided into smaller batches and processed throughout the day. Depending on when your CRMs batch pick up schedule runs, it may only pick up part of the fully processed sub-batches. At the end of the processing day, these will all have run and you will see your completed batch in your CRM.
