pxprocess | Friendly replacement for subprocess

I created a custom processing screen to transmit records to a web service but it returns a good record when it isn't. The web service always returns good record. To know if it is good or bad you have to loop through the response. Is there a way to stop that? I think I need to add a delegate, but everything I do fails. I keep being left with

The moment the good record comes back is when the Sendasync comes back. I've tried to mess around with a delegate but I can't get it to work. I think I need to create a delegate to do the error checking but either that is wrong or I use the wrong syntax.

Within the Acumatica 19.201.0070 framework I have created a custom processing page that utilizes PXFilteredProcessing with the old style processing UI public override bool IsProcessing => false; I have defined a cancel button (below) that will clear the graph and set some values of the processing filter.

I'm creating a Process to import items from an external API source into records in Acumatica.

I've created an unbound DAC that is used to represent the entries available from the external API.

How can I tell, within the graph processing logic, if it's being executed through a Scheduled task rather than through user interaction?

PXProcessing doesn't seem to have much, nor does the records within the AUSchedule table

Reason: If I'm in an interactive session, I want to redirect to multiple screens for the document(s) I've created. In a Scheduled task, I don't want to clutter up the server with these Redirects

I am looking to implement a DAC to use in a Processing Page where the data will not get persisted to the database.

The use case for this question is to have data loaded from an outside web service in preparation to generate AR payment records. We would like to have the user enter a dedicated Processing page and then be able to use the existing processing page framework to follow through with the generation of payment.

We need the processing page to call out to a web service and request any unprocessed payments then load the data into DAC instances to display to the end user before payments are selected to be processed. We don't see any reason to persist this data to the database, so I have been trying to get this to work using only non-persisting attributes in the DAC. The only way I can get close to doing this is to have at least one field be declared using a [PXDB{type}] attribute. If I try having them all use non-persisting, I get an error message as follows "Incorrect syntax near the keyword 'FROM.'"

I am also looking for a way to load the processing grid when the graph is first instantiated. I can load the data via a button, but the result needs to load whenever the processing graph is newed up. I will likely create a distinct ticket for this as to keep this ticket focused on the non-persistent DAC.

I have given a genuine attempt to look through the documentation on any clues how to do this but I have not seen anything yet in this specific use case. I assume I need to use a class level attribute to set this but have not had any success finding what needs to be used.

I am trying to create a routine to import orders from our EDI service into Acumatica. I have created a skeleton action:

Issue Summary:

The processing logic on my new screen is working but the page doesn't show any feedback to the user (e.g. Timer doesn't show, No Red/Green checkboxes, checkboxes aren't disabled)

Issue Detail:

I'm creating a processing screen that requires separate information from the user to be used by the processing delegate. The business logic works, but the user experience isn't like other processing screens. When you click Process there is nothing shown to the user. Normally the page refreshes the grid by disabling and showing only the selected items being processed, in addition to the long operation timer being added (then replaced by a green check or red x based on whether the process was successful or failed). When I click process all the entire grid's selected column is checked, but again nothing else changes (e.g. no timer, status, nor is the grid disabled). Ultimately both process and process all perform the business logic but the user doesn't see anything to indicate said success/failure.

The screen shows all customer locations because the process is updating some statistics that we are keeping for each location based on orders that exist for each location.
