AX / D365FO – Export Data Entity Enum fields labels in BYOD using Computed columns or Virtual fields

When you export a Data Entity in BYOD the base enums fields values are shown as integer values.

This is a big problem because it’s very difficult to understrand the real value of the field.

To solve this issue you can extend the standard data entity or modify a custom one using a virtual field or a computed column.

Using computed column

In this example we’ll add a new computed column to decode the PostingType enum field description.

First of all create an extension of the Data Entity (GeneralJournalAccountEntryEntity) and add the new virtual field (Al0PostingTypeDesc) by right-clicking on fields > String unmapped value

Set “Is Computed field” property to YES

Now create a new class and add a static method (getPostingTypeDescription()) like in example shown below

[ExtensionOf(tableStr(GeneralJournalAccountEntryEntity))]
final class Al0GeneralJournalAccountEntryEntity_Extension

{

     public static str getPostingTypeDescription()
        {
            SysDictEnum dictEnum = new SysDictEnum(enumNum(LedgerPostingType));
            Map mapping = SysComputedColumn::comparisionExpressionMap();

            for (int i = 0; i < dictEnum.values(); i++)
            {
                mapping.insert(
            SysComputedColumn::comparisonLiteral(dictEnum.index2Value(i)),
            SysComputedColumn::returnLiteral(dictEnum.index2Label(i)));
            }

            str comparisonField = SysComputedColumn::comparisonField(
        tableStr(GeneralJournalAccountEntryEntity),
        dataEntityDataSourceStr(GeneralJournalAccountEntryEntity, GeneralJournalAccountEntry),
        fieldStr(GeneralJournalAccountEntry, PostingType));

            return SysComputedColumn::switch(comparisonField, mapping, SysComputedColumn::returnLiteral(''));
        }
}

Now return to your data entity computed column and set the method (Al0GeneralJournalAccountEntryEntity_Extension::getPostingTypeDescription) to the “DataEntityView Method” property.

Using Virtual field

In this example we’ll add a new virtual field to decode the PostingType enum field description.

First of all create an extension of the Data Entity (GeneralJournalAccountEntryEntity) and add the new virtual field (Al0PostingTypeDesc) by right-clicking on fields > String unmapped value

Set “Is Computed field” property to NO

Then create a new class to extend the Data Entity Post Load method.

This customization will decode the integer value of the enum into the real description

[ExtensionOf(tableStr(GeneralJournalAccountEntryEntity))]
final class Al0GeneralJournalAccountEntryEntity_Extension
{

    public void postload()
    {
        next postload();
       
        GeneralJournalAccountEntryEntity generalJournalAccountEntryEntity = this;
        DictEnum enum = new DictEnum(enumName2Id("LedgerPostingType"));
        generalJournalAccountEntryEntity.Al0PostingTypeDesc = int2Str(enum.index2Value(generalJournalAccountEntryEntity.PostingType));

    }
}
