Find Records action in Power Automate Business Central connector
Coming to you in the coming weeks together with a cloud-based update of Business Central online connector for Power Automate is a new action allowing to find records based on a value (or any supported OData filter – more here). This will allow you to create both instant or flows in Power Automate that get a value from the user or any system in a form of automation, then find data in Business Central and then process data in business Central. An example of such scenario was shown ad Directions EMEA 2021 in Milan in a form of chatbot hosted inside Microsoft Teams and built using Power Virtual Agents – that chatbot took an input from the user, found an item in Business Central and came back with inventory data.
