Legacy Data

Legacy data encompasses information stored in an outdated Enterprise Resource Planning (ERP) system. Additionally, it may encompass data that is no longer in active use or actively maintained, but is retained for historical or other reasons. The process of migrating this legacy data to Dynamics 365 Business Central and Power BI can yield numerous advantages, such as enhanced data accessibility and informed decision-making. Moreover, it streamlines the expenses and intricacies associated with maintaining and updating obsolete systems or formats.

Prerequisite: Please make sure you have installed the Power BI Insights Connector App. 

To successfully import Legacy Data into Dynamics 365 Business Central, the process can be divided into two key steps:

  1. Import Data using Configuration Packages: This step involves importing the Legacy Data into Dynamics 365 Business Central utilizing standard Configuration Packages. 

  2. Approve Legacy Data: Once the data has been imported, the next crucial step is to review and approve the Legacy Data. 

Step 1: Import Data using Configuration Packages

1. Sign in to Business Central


2. In the Tell Me box, enter Configuration Packages, and then click on the 'Configuration Packages' link.

6. Fill the Excel file with legacy data. Do not modify the column structure. 
 

The following data is mandatory for legacy sales:

  • Bill-to Customer No.

  • Sell-to Customer No.

  • Posting Date

  • Document Type

  • Quantity (Base)

  • Sales Amount (LCY)

Please note that the legacy master data, such as Customers, Items, Salespeople, Locations, or Dimension Values, must already exist in Business Central. Only enter the respective Business Central Master Data numbers.


Specific columns:

  • Entry No. - this should be a sequential and unique number, for example, 1, 2, 3, etc.

  • Status - leave this column blank.

When the Document Type is Credit Memo, the Sales Amount, Cost Amount, and Quantity should be expressed as negative values.
