Exporting data from Dynamics 365 Business Central to Azure data lake storage

Project

This tool is an experiment on Dynamics 365 Business Central with the sole purpose of discovering the possibilities of having data exported to an Azure Data Lake. To see the details of how this tool is supported, please visit the Support page. In case you wish to use this tool for your next project and engage with us, you are welcome to write to [email protected]. As we are a small team, please expect delays in getting back to you.

Introduction

The bc2adls tool is used to export data from Dynamics 365 Business Central (BC) to Azure Data Lake Storage and expose it in the CDM folder format. The components involved are the following,

• the businessCentral folder holds a BC extension called Azure Data Lake Storage Export (ADLSE) which enables export of incremental data updates to a container on the data lake. The increments are stored in the CDM folder format described by the deltas.cdm.manifest.json manifest.
• the synapse folder holds the templates needed to create an Azure Synapse pipeline that consolidates the increments into a final data CDM folder.

The following diagram illustrates the flow of data through a usage scenario- the main points being,

• Incremental update data from BC is moved to Azure Data Lake Storage through the ADLSE extension into the deltas folder.
• Triggering the Synapse pipeline(s) consolidates the increments into the data folder.
• The data is now ready for consumption by analytics apps like Power BI,
  • via the data.cdm.manifest.json manifest file, or
  • via the raw CSV files for each individual entity inside the data folder

More details:

• Installation and configuration
• Executing the export and pipeline

Latest notable changes

Pull request	Changes
43	Intermediate staging data is no longer saved in CDM format. This eliminates potential conflicts during concurrent updates to the manifest. This does not affect the final data output, which continues to be in CDM format.
33	Fixing issue related to localizations of booleans and options/ enums.
31	Permissions corrected to direct permissions.
28	The AL app is upgraded to Dynamics 365 Business Central version 20. An archive has been created to keep the older versions at the archived folder.
23	The setting in Consolidation_OneEntity that limited concurrent execution of the pipeline to one instance has been removed. Now, an infinite number of pipeline instances is allowed to run concurrently.
20	Data on the lake can be chosen to be stored on the Parquet format, thus improving its fidelity to its original in Business Central.
16	The Consolidation_CheckForDeltas pipeline now contains a fail activity that is triggered when no directory is found in /deltas/ for an entity listed in the deltas.manifest.cdm.json. This may occur when no new deltas have been exported since the last execution of the consolidation pipeline. Other parallel pipeline runs are not affected.
14	It is possible now to select all fields in a table for export. Those fields that are not allowed to be exported, say flow fields, are not selected.
13	A template is inserted in the OnAfterOnDatabaseDelete procedure, so that deletions of archive table records, are not synchronized to the data lake. This helps in selected tables in the data lake continuing to hold on to records that may be removed from the BC database, for house-keeping purposes. This is especialy relevant for ledger entry tables.
