NAB - API error encountered

[spsuffern]

I built an APP in NAB to arrange invoices by future due dates. I added a [Refresh] button to the app calls an RPG program to refresh the data. When I click the button, it does call the program, but I get an error: [COLOR=rgba(0, 0, 0, 0.54)]API error encountered: CRTAPUNPAY[/COLOR] NAB [Refresh] button setup.JPGNAB [Refresh] button.JPG

Hello - Is there a MSGW? Or any clue in the job log?

[spsuffern]

I do not see anything in the logs and there doesn't appear to be any messages waiting. There is no errors recorded under Valence [Errors]. I only see this pop up message:
NAB [Refresh] button popup message.JPG
When I click [OK] the app works normally. The data is refreshed with the new data in file.

Good morning,

Should I just ignore this message for now or is there a way to fix it?

Is your job in message wait if not are you returning the response?

The front-end is showing that message because the call to your RPG PGM CRTAPUNPAY didn't respond or respond correctly.

On the NAB interface for "Call RPG Program". The action seems to be "Optional", so I am not sending a response back. Is this not correct?

Any time you're calling an RPG program from the front-end your RPG program always need to respond back. Also, action has nothing to do with the response from your RPG program. The reason for action is so you can have one RPG program handling multiple front-end requests.

Sorry for my ignorance. I had looked at documentation on line, but I wasn't sure how the responses would be handled for the buttons. You may want to add reference in the documentation to example [EXNABBTN] in the documentation for "adding a button" under "hide / show widgets" or a (?) similar to how you have "Intial Program" and "Filter Program" documented. I didn't realize that example was in the example source, but it is a great example. Thanks,

[Johnny Major]

Ok, thanks.

We do have a link in NAB that shows the example RPG program by clicking the question mark icon in the program field.
