AX 2012: LogisticsPostalAddress unknown value

Problem:

I learned something new about DateEffective tables today. I had a customer requirement to store addresses in a Standard AX table, PdsApprovedVendorList. So I created a relationship between my table and LogisticsPostalAddress table, adding foreign key to LogisticsPostalAddress to my table. Then I added this field to a form and set ReplacementFieldGroup property of the control to LocationReference.

Everything worked as expected but the problem surfaced when user modified one of the addresses in the Global Address Book which were referenced in my table. The custom field began to show Unknown for the address that was updated by user.

Resolution:

1. Add new Reference Data Source of LogisticsPostalAddress to the data source of your table on the form.

2. Add the following lines of code to the form’s init method:

legManufacturerAddress_ds.addFieldToSelectionList(fieldNum(LogisticsPostalAddress, ValidFrom));
legManufacturerAddress_ds.addFieldToSelectionList(fieldNum(LogisticsPostalAddress, ValidTo));
legManufacturerAddress_ds.addFieldToSelectionList(fieldNum(LogisticsPostalAddress, CountryRegionId));

3. Add the following lines of code to the executeQuery() method of parent data source to which reference data source is added before super() call. In this case, it is PdsApprovedVendorList.

legManufacturerAddress_ds.validTimeStateUpdate(ValidTimeStateUpdate::Correction);
legManufacturerAddress_ds.query().validTimeStateDateTimeRange(DateTimeUtil::minValue(), DateTimeUtil::maxValue());

Reason:

LogisticsPostalAddress is a DateEffective table. When user modifies an existing address, system creates a new record instead of updating the existing record. That’s why references do not get resolved after address modification.

AX 2012: Getting ReferenceGroup Control

Getting ReferenceGroup control automatically while dragging a datasource field to a form control is little tricky. Even if you have defined relations correctly at the table level, you might not always get the reference group control for a foreign key in the table. See the solution below for this issue.

Problem:

Consider for example, two tables:

1. FAZCourseTable
2. FAZEnrollmentTable

where FAZEnrollmentTable contains the foreign key of FAZCourseTable as follows:

But when I drag this foreign key field from datasource to grid control, I get Int64Edit control instead of ReferenceGroup control.

Resolution:

To get the ReferenceGroup control, perform the following development steps:

1. Create unique index on FAZCourseTable for the natural key of the table which in this case is Code field.
2. Set AllowDuplicates to No on the index properties.
3. Set AlternateKey to Yes on the index properties.

4. Set ReplacementKey to CodeIdx, name of the index just created, on the table properties.

5. Delete the Int64Edit control created earlier on the form.
6. Drag the FAZCourseTable field from the datasource to the grid control node.
7. You should be getting the ReferenceGroup control now.
