Hi Thoma,

You can try the IDataUnpacker.GetDataStore() method:

https://docs.appeon.com/appeon_online_help/powerbuilder/api_reference/PowerBuilder.Data/DataStoreExtensions/Method/GetDataStore.html

sing SnapObjects.Data;
using PowerBuilder.Data;
using System;

namespace Appeon.ApiDoc.DataStoreExtensionsExamples
{
    public class GetDataStoreExample
    {
        private readonly SchoolContext _context;

        public GetDataStoreExample(SchoolContext dataContext)
        {
            // Sets the data context.
            _context = dataContext;
        }

        public void Example1(IDataUnpacker dataUnpacker)
        {
            // Gets the DataStore object from dataUnPacker according to the key
            var ds = dataUnpacker.GetDataStore("student");

            // Shows the students.
            for (int i = 0; i < ds.RowCount; i++)
            {
                Console.WriteLine("Row Status: {0}",
                    ds.GetRowStatus(i));

                Console.WriteLine("First Name: {0}",
                    ds.GetItem<string>(i, "FirstName"));
                Console.WriteLine("Last Name: {0}",
                    ds.GetItem<string>(i, "LastName"));

                Console.WriteLine();
            }

            /* This code example produces the following output:
            
            Row Status: NewModified
            First Name: Lena
            Last Name: Sherwood

            Row Status: NewModified
            First Name: Davies
            Last Name: Adam
            */
        }
    }
}
