Data entity key field code-level identification

(0) ShareShare
ReportReport
Posted on by tgudwanski 32

Hi.

Could I ask for help in finding any clue (if possible) about the way to identify which of the specific data entity fields are defined as its key fields?

Using the idea found in the following post  https://metadataofdataentityinax7.blogspot.com/ I was able to fetch data entity specification and prepare it in JSON-like format requested by the customer, however I couldn't find a way to accomplish the above.

Or maybe there is a system built-in way to extract given data entity's schema in any possible format?

Thanks in advance for any help on this.

Kind regards,

Tomek.

    Great thanks Martin for your prompt answer!

    I've managed to check it and it works perfectly. Seems to be a good tool, much more accurate than using Dict* classes in this case.

    Wish you all the best :)

    You can extract this information from the new metadata API that was introduced in AX 7.

    Here is an example:

    Microsoft.Dynamics.AX.Metadata.MetaModel.AxDataEntityView entity;
entity = Microsoft.Dynamics.Ax.Xpp.MetadataSupport::GetDataEntityView("HcmEmployeeEntity");
        
var key = entity.Keys.get_Item(entity.PrimaryKey);
System.Collections.IEnumerator enumerator = key.Fields.GetEnumerator();
while (enumerator.MoveNext())
{
    Microsoft.Dynamics.AX.Metadata.MetaModel.AxDataEntityViewKeyField field = enumerator.Current;
    info(field.Name);
}
