Hi,

I have gallery that contains two columns, one for process steps, and the other is their sequence numbers. I'd like to overwrite the entire columns of an existing table (same structure), with the entire contents of this gallery. How can I do that?

I'm only using CDS and no external lists (e.g. SP, etc.). I'm looking for a solution that does not require using external data sources. Many thanks!

Overwrite gives an indication of replacing the data in the Gallery. To get the structure of the Table use ClearCollect;
ClearCollect (ColOverwrite, Datasource);
Clear (ColOverwrite)

That gives an empty structure. Now what do you want to put into the Table structure

@eka24 . Sorry if the message wasn't clear. I want to take all the items in the gallery, and write it into an existing CDS entity/ table that contains data.

You can Patch the Gallery or the Collection using following;
Gallery:
ForAll(Gallery1.AllItems, Patch(
Datasource,
Defaults(Datasource),
{Column1: Title},
{Column2: Category}))

For a collection;
ForAll(Collection1,
Patch(Datasource, Defaults(Datasource), {Column1: Title,
Column2: Category}))
------------

@eka24 . The formula you gave partially works. It writes all the data to the correct columns in my entity, but instead of overwriting, it's adding them as records. Is there a way to overwrite the data in the entity?

@eka I've found the answer. I removed all the values from that entity using the "Remove" function, and re-wrote all the values from gallery into it.
Thanks for your help!
