About the Blue Prism Integration
The RWM application was deprecated with Appian 24.1. The application will no longer be updated or pre-installed for new Appian Cloud sites with Appian RPA enabled.

RWM will be removed in a future release and we encourage customers to use the Operations Console to manage robots instead.

Introduction

This page provides an architectural overview of RWM when used with Blue Prism. It describes the Blue Prism and Appian application objects that support integration between the two applications. This information helps demonstrate the dependencies between the two applications, so you can fully understand the impact of changes you plan to make.

Refer to this document as a resource for modifying or maintaining your RWM instance when Blue Prism is your RPA vendor.

About the Blue Prism integration

For most supported RPA vendors, RWM uses the vendor's public APIs as a means of transmitting data to display in the application. However, Blue Prism doesn't use publicly available APIs. Instead, when you set up RWM with Blue Prism, you imported a package into Blue Prism and configured the contents to communicate with RWM.

Blue Prism processes

Blue Prism and Appian communicate with each other most prominently through processes. There are a number of objects in each environment that are used in each process. Refer to the Object references table to understand the dependencies.

RWM Test Appian WebApi Call

This process tests the connection between RWM and Blue Prism. Before you run this process, expose it as a web service by going to System > Process > Exposure > Expose a Process.

After you run this process, an entry appears in the Appian database table RWM_BP_ETL_LOG to indicate if it was successful.

  • RWM_testAppianWebAPICall

RWM Trigger Process

This process runs the scheduled and manually started Blue Prism processes from RWM. It triggers the RWM Schedules process, which checks the RWM Load Process queue to see if there are pending items to process. Items in this queue represent requests to start or schedule processes, which Blue Prism receives from Appian. When one of these items is processed, the request is granted and the corresponding process is either scheduled or started.

The process occurs every three minutes by default, but you can configure this value.

RWM_GetDataFromBPtoAppian

This process extracts, transforms, and loads (ETL) data to Appian from Blue Prism. The process performs ETL on historic or daily data. It triggers the RWM ETLScheduler process in Blue Prism, which occurs every 15 minutes by default, but you can configure this value.

The process executes a historic data load or a daily data load based on the value in the RWM HistoricUpdate Flag environmental variable. It loads historic data when set to true and daily data when set to false. Learn more about modifying historical load in Blue Prism.

When loading historical data, it uses the values in RWM HistoricQuery StartDate and RWM HistoricQuery EndDate to determine the timeframe for data. The first time this process is executed, a new item is added to the RWM ETL Check queue. When the process is complete, this item is updated with the end time for subsequent executions to reference. This item is updated with this information for each execution.

When loading daily data, the process uses two timestamps to determine the data to load: the time the last execution started (captured in the item, used as the start time) and the current time (used as the end time). The daily load won't be able to fetch data if this item doesn't exist in the queue. Therefore, the historical data must be loaded at least once before you run a daily data load. After the process completes, the end time is captured in the work item for future reference.

RWM_GetPreProcessedQuery

This is a sub-process of RWM_GetDataFromBPtoAppian. It will contain both the historic and daily SQL query in a collection variable. Based on the execution type, either daily or historic query will be passed on to the parent process.
