Mapping for data entity extension

Hello everyone,

I just wanted to link my custom map to a data entity extension.

I am just creating the new mapping, I am getting MyCutomMap.Field1 == .Field1

But it should be MyCutomMap.Field1 == DataEntityExtension.Field1

Because of this, I am getting errors saying field with Id '0' doesn't exist.

Is it possible to link the map to the data entity extension?

If yes, How?

Thanks.

Moved to D365 Finance forum.

Can you show a screenshot of your situation?

At least when I have a Map that has mapping to a standard table, I see also my extension fields in the field list. For example CustTable.MyField.

After all, you used the extension to add fields to the standard object.

Just to make sure that I understood correctly:

- You have created a data entity extension

- You have added some fields to the data entity extension

- You have added your Map object in the Mappings of that data entity extension

- You would like to map a field of that map into your custom field in the data entity extension

I tried it quickly but the lookup for the field mapping just freezes. If I don't use the lookup and I type a field name, it works as you described (=wrong), no matter if I try to map it to a custom field or a field in the standard entity.

What are you trying to achieve?

Yes, exactly the same situation.

What I am trying to do is map few custom fields and few standard fields to my map,

And on modification of those fields, I mean when modifiedField method(of data entity) is called for any of those fields, I should call respective methods in the map.

This should be the case with few other entites also, so need to do similar thing there also

I dont want duplicate code in each entity, so thought I could use maps.

Is there any other option to achieve this?

Seems that is a name issue(=.Field),

I was getting error saying field Id with '0' doesnt exists in map, when I tried calling map method from data entity,

And in map, it was throwing error where I used those fields.

But when I restarted IIS, It is working as expected.
