Processing Screen - can I make Acumatica allow me to be able to manually add items to a grid?

I had a similar task — implementing a processing screen for custom data handling in Acumatica.

After thorough investigation, I found that the PXProcessing attribute, commonly used for processing rows in a processing screen, is read-only. Therefore, it cannot be used like a typical PXSelect or SelectFrom view that allows inserts or updates.

Solution

The best approach is to reuse the same DAC and separate the functionality into two screens:

1. Data Entry Screen – for importing or editing records. (MK101000 in my case)

2. Processing Screen – for executing logic against the imported data. (MK505000 in my case)

public class CreateUserEntry : PXGraph<CreateUserEntry>
{
    public PXSave<CreateUserbyEmail> Save;

    [PXImport(typeof(CreateUserbyEmail))]
    public PXSelect<CreateUserbyEmail> Emails;
}

This screen allows users to import or manually enter email addresses for processing.

public class CreateUserProcessing : PXGraph<CreateUserProcessing>
{
    public PXCancel<CreateUserbyEmail> Cancel;
    public PXProcessing<CreateUserbyEmail> Emails;

    public CreateUserProcessing()
    {
        Emails.SetSelected<CreateUserbyEmail.selected>();
        Emails.SetProcessDelegate(Process);
    }

    public static void Process(CreateUserbyEmail entry)
    {
        if (entry == null || string.IsNullOrWhiteSpace(entry.Email))
            return;

        var graph = PXGraph.CreateInstance<CreateUserProcessing>();
        graph.CreateUser(entry);
    }

    private void CreateUser(CreateUserbyEmail entry)
    {
        // Implement your user creation logic here
    }
}
This screen uses the PXProcessing view to process the entries entered in the Data Entry screen.

Notes

• Use [PXImport] in the entry graph to support Excel imports.

• Use PXProcessing<T> only for processing (not editing).

• This pattern follows Acumatica's intended architecture and provides a clean separation of concerns.
