Summary0034287: Entity vs Import Qualifier
DescriptionHavning a process with a service defined as Transaction (so it does use queues, import entries)
As you know for this processes we define:
- An entity:
@DataSynchronization(entity = "XXX")
- An import qualifier:
  protected String getImportQualifier() {
    return "YYY";
  }
We were always assuming that this XXX = YYY, but this is not correct. For example in the case of Cancel Layaway the entity behind is a Layaway (Order) but the import qualifier should be the process: OBPOS_CancelLayaway (for example). We noticed this due to an error that now is thrown due to the validation you added for synchronized mode (afterReturnFromCentral). This validation is querying to retrieve the record in the other server (check DS). As we were using process name as entity, process was failing when trying to get object behind 'id' for non existing entity (OBPOS_CancelLayaway).
This took me to change entity = Order, importQaulifier = OBPOS_CancelLayaway. and this worked fine. But as well a new problem raised.
Let me explain, when preference for synchronized is not there (equals 'N') and an error occurs, an import error is raised and there the API is using entity for the importdatatype. That's a problem because I think it should map to the importQualifier (so that process can be run again when fixing error)
Steps To ReproduceCreate a Layaway in an env with synchronized preference equals Y.
Cancel it using cancel Layaway process.
System fails due to wrong entity (OBPOS_CancelLayaway).

Subclasses of DataSynchronizationProcess have an annotation to tell which entity is handled by the DataSynchronizationProcess (e.g. [1]). The value in the annotation must be a real entity name becauses the annotation is used by DataSynchronizationProcess [5] to find the entity covered by the DataSynchronizationProcess. If an entity is not found then several parts of the code get into an error [4].

Eduardo's team had some issues with it [2] and set the CancelLayawayLoader entity annotation to Order, after discussing with me. But in hinsight this gives issues as there are now 2 DataSynchronizationProcess with the same annotation ([1] and [3]). This gives problems when processing any errors [6] as there a unique entity name is expected to find the implementing DataSynchronizationProcess.

So my take:
- the @DataSynchronization(entity="...") must be unique and may contain non-entity names
- if the annotation has a non-entity name then the implementing class must override the getEntity method to return the real entity
- when creating the error handler the value of the annotation-entity name should be used.

Very confusing topic... Let me know what you think.
