Its been a while since I have posted on my blog but I hope to keep some momentum going forward.
So the team at Microsoft Dynamics have been making some significant changes to the way we build customizations for Retail based on the feedback gathered from customers / partners. You can catch up with these changes by registering for the techtalks that are lined up by using the link below.
Upselling is one of the common requirements in Retail POS. In this post I would like to recap how this can be achieved using configuration and no code in Dynamics 365 for Operations using info codes.
Info codes is quite an old feature and I thought it would be good to recap how we can use it to achieve “Upselling”.
Lets say we want the cashier to remember to try to upsell a product B on purchase of a certain product A (association rules)- example to prompt cashier to ask customer if he or she would like to buy batteries with purchase of camera.
The first step would be to create an infocode that will show a prompt to the cashier in the Retail POS. Infocodes can be created in Dynamics 365 in the following path- Retail and Commerce-> Channel setup -> Info codes
The input type of the info code can be setup as subcode buttons.
The subcodes need to be setup as follows. Note the use of Trigger function and Trigger code in the setup.
The above setup means that on selecting Yes, the customer agrees to buy the product we are trying to upsell (batteries) and the product will be added to the transaction.
The next part of the setup involves linking this info code to the product the cashier sells in the first place to the customer (Camera). This can be done in the released products master under Commerce tab-> Set up-> Info codes.
With the above setup in backoffice and pushed to the POS (by running the 1030 job and 1040 job), the cashier will get a prompt as shown below
On clicking Yes, the upsell will be done by adding the Batteries product to the transaction.
End users (Operations team and Purchase) started reporting that the Purchase Order status is changing automatically without them changing anything. The environment on which this issue was reported is Platform Update 32 – 10.0.08.
The purchase order status was changing from Confirmed to Approved and when Operations tried to GRN the order it caused an error –
“Purchase order is no longer confirmed. Posting of the order has been cancelled”.
I was trying to backtrack and check what was the code deployed in the last few packages that could have caused it, but found no code that could have caused this issue.
Finally I suspected that its a bug in the standard itself. I searched LCS and found the following issue-

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)
When trying to build the MPOS solution on my laptop, I got the below error.
Error APPX0501 Validation error. error C00CE169: App manifest validation error: The app manifest must be valid as per schema: Line 10, Column 50, Reason: —————‘ violates pattern constraint of ‘(CN|L|O|OU|E|C|S|STREET|T|G|I|SN|DC|SERIALNUMBER|Description|PostalCode|POBox|Phone|X21Address|dnQualifier|(OID\.(0|[1-9][0-9]*)(\.(0|[1-9][0-9]*))+))=(([^,+=”<>#;])+|”.*”)(, ((CN|L|O|OU|E|C|S|STREET|T|G|I|SN|DC|SERIALNUMBER|Description|PostalCode|POBox|Phone|X21Address|dnQualifier|(OID\.(0|[1-9][0-9]*)(\.(0|[1-9][0-9]*))+))=(([^,+=”<>#;])+|”.*”)))*’.

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.
So here is an interesting tidbit from a recent incident in which I was supporting the customer on Dynamics 365 for Operations – Retail.
Few transactions were suddenly reported as “Missing” by the customer. The customer provided transaction details including CCTV grab along with Credit Card Slip. I started my investigation the server logs and found that the transaction id seemed be used across two transactions. This meant that the cart was not got getting cleared. In my customization I needed to access the cart information post the cart checkout and my cart clearing code was written in the PostEndTransactionTrigger.
We also logged a support ticket with MS and over time understood from MS that the MPOS is being exited by the cashier without closing the Change Due Dialog, which resulted in the PostEndTransactionTrigger not executing.
Long story short, if you are using this Trigger, make sure it contains non -critical code as it may not trigger if user exits MPOS without closing the above change due dialog.
This article is based on 7.1 Retail SDK but should be applicable to later releases too unless a fix for this has been released.
