Dynamics 365 for Retail Upgrade – Backward compatibility

Been a while since I last posted as I was busy with upgrading our implementation from v7.1 to v10. During our upgrade from Dynamics 365 for Retail v7.1 to v10.0, one of the main issue we faced is that of Backward compatibility.

The issue occurs when trying to run v7.1 MPOS with v10.0 Retail Server, basically “Declare Start Amount”feature does not work.

On trying to declare the start amount the cashier gets the following prompt.

On trying to key in any value, the start amount results as NAN.

Reattempting to declare the start amount simply repeats the above prompts. Now this issue is serious since it prevents the closing of shift as shown in the screenshot below.

My investigation started with debugging the MPOS code and eventually the CRT code, and I found that one of the fields “StartingAmount” had been removed from crt.ShiftsView. This was causing its value to stay as undefined.

The good news is that issue is reported to Microsoft, and we are currently awaiting the fix (currently expected in v10.0.4)

MPOS Build Error – App manifest validation error: The app manifest must be valid as per schema

When trying to build the MPOS solution on my laptop, I got the below error.

It took me a while to figure it out but this was happening because certain features in Visual Studio were not installed, the Retail SDK Handbook helped me to confirm which features were needed to be installed. After installing the highlighted features, I restarted the machine and the solution built successfully.

MPOS randomly switching from online mode to offline

In my recent Dynamics 365 for Operations implementation on 7.1, we encountered an issue with MPOS switching to offline randomly . MPOS as we know switches to offline either when triggered manually or when the switch is seamless (automatically) when there is any issue in the communication between MPOS and D365 Retail Server, an example is a network interruption (for more information on the overall Retail Topology do refer this link MPOS Technical Architecture)

In a usual scenario, when an interruption occurs in between a transaction, cashier would get an error message the Cart State has changed. The cashier would need to void the transaction and then start all over again and end with creating an offline transaction (Not the kind of experience you want when you have a queue of customers at the billing).  Another issue that coupled with this was that the MPOS logo would not switch from offline to online when the MPOS mode switched.

 

Bottomline –

Make sure you uptake following binary hotfixes as soon as you can if you have enabled MPOS in offline mode

KB 4049328 – MPOS offline logo issue

KB 4058723- Set of reliability fixes for POS Offline

Also include the following X++ hotfix which complements the above binary fix

Cannot create a record in Global address book (DirPartyTable). The record already exists

This article is the outcome of a shared session with credit to my friend Vishal Kohli .

StoreMaster

 

While creating a new store in the store master in Dyn365FO, you may face the following error.

“Cannot create a record in Global address book (DirPartyTable). The record already exists.”

The issue is that the operating number keyed is already existing in the system. Therefore you need to make sure you key in a number that does not already exist. The error message can be a little confusing in this regard, which is why I thought this warrants a post.

Note -You are most likely to face this issue when your operating unit number sequence is configured as Manual.

Hope this helps!!

MPOS AAD changes – The reply address does not match the reply addresses configured for the application

If you are on Dynamics 365 for Operations 7.1 and planning to uptake the latest set of binary hotfixes, expect to see the above error when trying to activate MPOS.

Sergey from Microsoft has described the change that is triggered by binary hotfix KB4051347 in below link in great detail. Just one note though if you are on 7.1 you will not find the event ID 40619 in the event viewer. Its only available 7.2 onwards.

In case you are interested to know more about these changes the below link is a great video that describes the differences between ADAL versus MSAL –https://channel9.msdn.com/Events/Build/2017/P4031

[AX 2012 R3 / Dynamics 365 for Operations -Retail]: Viewing events from MPOS in Event Viewer

This post is based on a conversation in Dynamics AX Community (link attached later in the post)

 

Events from the MPOS in AX 2012 R3 can be found in Event Viewer here:

Application and Services Logs -> Microsoft -> Windows -> AppHost -> AppTracing.

activate the event log using Event Viewer.

  1. Navigate to Application and Services Logs -> Microsoft -> Windows -> AppHost.
  2. Right click AppHost and Select View -> Show Analytic and Debug Logs

Events from the MPOS in AX 7 / Dynamics 365 for Operations can be found in Event Viewer here:

Event Viewer: Applications and Services Logs->Microsoft->Dynamics->Commerce-ModernPos.- Admin, Debug, Operational (where Operational would contain errors and Debug is by default disabled but can be Enabled if needed.)
