==============

Purpose:

Understand when and how to use postLoad method in data management.

Application:

Dynamics 365 for Finance and Operations

Prerequisites:

• Basic understanding of data entities and how data management works

Business requirement:

Consider, for example, we need to add new field to standard data entity EcoResReleasedProductV2Entity to export a custom field called Manufacturer.

If we come across this business requirement to add a new field to a standard data entity to export additional information then we can achieve this requirement by using the postLoad() method.

PostLoad:

PostLoad() method can be used to provide values in export scenarios for unmapped fields which are created as non-computed fields (Is Computed Field property is set to No) on a data entity.

In the code below, we can see how we can use postLoad() method to populate a custom field added to a standard data entity to export additional information from released products.

Please note, you will need to add a virtual unmapped field to the data entity first before you could use this code.

Code

[ExtensionOf(tableStr(EcoResReleasedProductV2Entity))]internal final class MAK_EcoResReleasedProductV2Entity_Entity_Extension{ public void postLoad() { InventTable inventTable; MAK_ManufacturerTable manufacturerTable; next postLoad(); inventTable = InventTable::find(this.ItemNumber); manufacturerTable = MAK_ManufacturerTable::findRecId(inventTable.MAK_Manufacturer); this.ManufacturerId = manufacturerTable.ManufacturerId; }}
