Quite a while ago I wrote a blog post about postTargetProcess method that could be added to a data entity for post processing. Previously, you could add it only to a newly created entity, but now you can extend any entity using CoC.
This method is a bit special because it is not declared on the parent object, but is called via reflection by DMFEntityBase class. Full list of method that work in the same way:
DMFEntityBase uses tableHasStaticMethod() to check if a method is defined and DictDataEntity.callStatic() to call it. In the latest PUs Microsoft added support of CoC methods to Dict* API and reflection methods, so now it is possible to use CoC method in this scenario as well.
Extension is quite simple and straightforward, all you need to do is to declare static method with respective signature and do not call next because this method is not defined on the parent object:
final public class MyDataEntity_Extension
public static void postTargetProcess(DMFDefinitionGroupExecution _dmfDefinitionGroupExecution)
In Dynamics 365 for Finance and Operations virtual companies are deprecated and could not be upgraded according to the documentation that just state this fact without proposing a solution.
If we cannot upgrade, then we need to get rid of them. Here are the high level steps how you can de-virtualize a table. Let’s say that we have virtual company V with two companies: A and B. V has only one table collection with one table for simplicity, let’s call it Table1.
- Delete a data from Table1 that belongs to the companies A and B. When you create a virtual company, you may already have some data in the tables you want to share. That data may be orphaned, so we want to delete it to avoid duplicates. Can be done via simple T-SQL script:
DELETE FROM Table1
WHERE DATAAREAID = 'A' or DATAAREAID = ‘B’
- Go to System administration > Setup > Virtual company accounts and delete the virtual company.
- Restart AX client.
- Insert data from the virtual company to de-virtualized companies via X++ job:
static void deVirtualizeTables(Args _args)
DataAreaId virtualDataAreaId = 'V';
container oldCompaniesCon = ['A', 'B'];
void deVirtualizeTable(TableId _tableId)
SysDictTable dictTable = new SysDictTable(_tableId);
Common buffer = dictTable.makeRecord();
while select crossCompany buffer
where buffer.dataAreaId == virtualDataAreaId
for (i = 1; i <= conLen(oldCompaniesCon); i++)
dataAreaId = conPeek(oldCompaniesCon, i);
newBuffer = null;
newBuffer = dictTable.makeRecord();
select firstOnly RecId from virtualDataAreaList;
throw error('Delete a virtual company first!');
- Delete data from the virtual company. It cannot be done from X++ because you cannot use changeCompany with a company that does not exist. T-SQL:
DELETE FROM Table1
WEHERE DATAAREAID = 'V'
Now we are ready to run standard data upgrade procedure!
