Duplicating a Record in a CDS Custom Entity

Hello Community,

aksing for a hint.


I want to duplicate a Record in a Custom CDS Entity.

1) I have a DataTable Control on the Screen (i.e., one record is always selected).

2) I want to duplicate selected record with a command






, which doesn't work. => I assume because the command tries to copy also "System" fields which are not allowed to be changed.


I am assuming that, because if I try to duplicate a record with a slightly different command, i.e., with a list of the fields to be copied



Patch('Activities',Defaults('Activities'),{'Belongs To':DataTable.Selected.'Belongs To', ... (some other fields)})



, then command is executed as expected.


Is there a better way to duplicate existing record, i.e., without listing all the fields to be inluded into duplication? <= just to save some time with coding, I mean


Still learning!






Accepted Solutions

It seems it can't be done without listing all the fields that have to be copied, leaving out those that are "system" fields (i.e., no write permition).

You can either switch to a Gallery and insert a button into the Gallery.


Also Onselect of the Datatable;

{FirstName: CollectionName. FirstName,
ReceipientName: CollectionName.ReceipientName,
FullName: CollectionName.FullName,
EntryDate: CollectionName.EntryDate})

Hi @RMC-Pro 

In a properly constructed relational database, I cannot think of a reason to duplicate a record unless you are moving it to another database. 

Hello @Drrickryp ,
creating a record, then changing a few fields (actually just a field or two).


<= would that make sense? Maybe I am using wrong approach, but can't think of better one.


Tnxs anyway.



Hi @RMC-Pro 

If you are going to be designing Apps using PowerApps it would be in your best interest to learn the basics of relational database design.  I have a series starting with an overview to help you master the principles and apply them to PowerApps. .  

Hi @Drrickryp,

like the series, very insightful, but doesn't give te answer to my question.

Thanks anyway.


Keep up the good work.
