Is there anyway to get meta data values in collection ?

[PowerApper25]

Hello,

I am manipulating datasource of CDS Entity with more than 2000 records through formulas in my powerapp, however for large data source I was recommended to use collection, so I did that, but, when I do that I am unable to use fields created through relationship and metadata fields like "Created By"

These fields are always blank in collection, and therefore I am unable to use them - is there any way to add fields in collection while create them to add data from the actual data source ? Or is there any alternative way ?

Cheers,

Hi @PowerApper25 

It is not usually necessary to use collections for CDS entities as most functions are delegatable, even aggregating functions. delegation-of-aggregate-functions-for-cds/ .  I usually just see if I can use the datasources directly and consider using collections if I run into a problem.

Hi @PowerApper25 ,

The reason why you can't save some meta data values in collection  is that some of them is lookup fields.

For example, save created by filed should use:

ClearCollect(test,tablename.'Created By'.'Full Name')

However, meta data is read-only. You could display them in PowerApps, but you can't write data to meta data fields.

CDS is delegable data source, you could use it as data source directly.

Try to use delegable funtions.

Here's a doc about delegable funtions in CDS:
