Database error during POS activation

For some reason – still to be discovered – I once in a while get a number sequence error while activating a POS.

getting last number sequence failed

It’s not super informative but going through the event log we find this:

An exception of type: 'Microsoft.Dynamics.Commerce.Runtime.StorageException' occurred while executing Microsoft.Dynamics.Commerce.Runtime.Messages.StartSessionRequest request by Microsoft.Dynamics.Commerce.Runtime.Workflow.Security.StartSessionRequestHandler.

So the problem/symptom is centred around RetailTransactionTable. I haven’t found the actual source of the problem and what I’m suggesting as quick’n’dirty fix is not to be used in a live environment or anywhere else but sandboxes where it won’t affect anything close to live data.

I create a new query on the SQL server running the retail server database and use the following TSQL to rename a transaction id:

update [AxDB].[ax].[RETAILTRANSACTIONTABLE]
set TRANSACTIONID = '<transactionid_found_in_event_log + something else like a B>'
 where TRANSACTIONID = '<transactionid_found_in_event_log>'

After that the retry button brings you back on track and the activation can continue:

Activation success

As said, it ain’t pretty and I do not suggest this as a solution to be used anywhere. But it will get you passed that error. There’s probably a better solution and maybe a root source, but until then …

Oh, and I do not take any responsibility of bad things coming out of this … 😉

Using hardware station from Windows Phone MPOS

Microsoft released the MPOS for Windows Phone a while ago and although a bit rough to install it works very well.

Next step was to get it to work with my wireless receipt printer through a hardware station. As you might now the connection to a hardware station can be tested through the url https://<MyHardwareStationAddress&gt;:<port>/hardwarestation/ping. And as expected it didn’t work right away since I hadn’t installed the certificate on my phone.

I figured that it couldn’t be that hard, but since you are reading this you might have guessed that it wasn’t all that easy.

I had earlier on exported the certificate on my hardware station as a .pfx file and used that with success. But that wasn’t the case on the phone. I imported the .pfx file and used the Certificate app to see the status of the certificate.

I knew the certificate was working on other POS machines but here it wouldn’t accept it as valid:

certificate-not-working

After consulting google for a while I read that people had solved issues like this by using .cer exports instead, but that didn’t solve anything for me.

What I ended up doing was exporting it as .p7b. Only thing is that if checked the “Include all certificates in the certification path if possible” I still had a non valid certificate on the phone. So I exported it like this:

export-certificate

And now I have a working certificate:

certificate-working

Actually I think that it is more than just Okay; but anyhow …

The hardware station was now allowing pairing and selecting:

hardware-station-paired

 

Retail operations and user rights

In this post I will do a quick explanation of the user rights setup of the retail POS operations.

Operations is referring to the different actions available in the POS. They are listed in Retail and commerce/Channel setup/POS setup/POS/Operations. Each operation has the following information:

Operation id and Operation name identifies the operation.

Permission ID 1 and Permission ID 2: These permissions can be a required level of rights needed for the operation.

Check user access: If not set the operation does not require the user to have the required access.

User operation: If not set you cannot create a button on the POS for that operation. Notice that the form by default has a filter on that field requiring the field to be set true.

Confused? Let’s have a look at an example.

We are going to focus on the void product operation using worker 000120 (Andrew Lan) and 000110 (Dan Park). Dan is allowed to void transactions:

danp-pos-permissions

Andrew is not:

andrewl-pos-permissions

Scenario 1:

Check user rights = true

Permission IDs = 0

Andrew tries to do a void:

void-transaction-not-allowed

Since Andrew has limited rights he cannot void the transaction.

 

Scenario 2:

Check user rights = false

Permission IDs = 0

In this case the POS doesn’t care what about permissions when voiding transactions so it allows Andrew to void:

void-transaction-prompt

 

Scenario 3

Check user rights = false

Permission IDs = 1001 (Allow transaction voiding)

Like in scenario 2 the POS still doesn’t care about user rights so it allows Andrew to void the transaction:

void-transaction-prompt

Scenario 4

Check user rights = true

Permission IDs = 1001 (Allow transaction voiding)

The user rights are validated again and since Andrew isn’t allowed voiding he can’t do the void. But now we have added the feature that Andrew can call in his manager or anyone else with enough rights to allow transaction voiding:

cannot-void

In this case he gets Dan to type in his id and password and this opens up for voiding the transaction:

void-transaction-prompt

 

Peripheral Simulator in new release of Dynamics 365 Operations

With one of the latest releases of Dynamics 365 Operations we have the option of simulating hardware peripherals like printers, cash drawers and so on.

The idea is to allow the user to simulate the flow of the retail processes including printers, drawers, scales, payments and so on but without having to occupy your co-workers desk piling up all of your retail hardware.

Here is what you need to do. Start by going to the hardware profiles. In the demo data a new profile has been added called Virtual. It has been set up with a profile that will work pretty much out of the box.

Besides the data a new button has been added allowing the download of the simulator:

hardware-profile-and-download-button

The simulator download hasn’t received the prettiest name, but that aside it is working great.

peripheralsimulator

The installer is very much a next-next-next installer and does not require any action taken unless you have specific wishes regarding installation folder.

Once installed you get this new application:

retail-peripheral-simulator

Already at this point we get an idea of what to expect. But before getting everything up and running you need to do a couple of more things.

First, we need to tell the store that the hardware station should use the new hardware profile:

hardware-profile-o

Run your 1070 and 1090 jobs (depending on which setup changes you made).

Now, starting up the POS you might end up with a series of hardware station errors that could look something like this:

hardware-station-error-3hardware-station-error-2comm-error-cash-drawer

To get passed this we should shortly touch upon how this works. According to the hardware profile we are using all communication is OPOS based so we need to get that onboard our POS machine as well. I used this one that previously was recommended during the installation of the POS software: Link to OPOS software

With that done you should be ready to start up your POS. You might have to manually go in and enable the use of the hardware station.

So first test could be a safe drop. In this case I pull out 10 USD:

make-safe-drop

That leaves a safe drop receipt in the printer:

safe-drop-receipt

And the drawer needs to be closed again:

cash-drawer-open

Click the Close drawer button to close it:

cash-drawer-closed

Let’s sell something. In this case a shirt:

transaction

I would like to pay this with a credit card so I switch to my simulator and select the MSR.

no-card-created

Click the + button to create new card:

create-master-card

The number is found on this page: credit card generator

Next step is to click the Pay card button in the POS followed by the Swipe card button in the Simulator. This adds the card info to the tender information in the POS:

card-details-in-pos

Completing the transaction you get a receipt in the printer:

receipt-from-transaction

This will definitely change the way we make demos of the POS with Dynamics 365 Operations.

 

Background images on AX POS

The POS UI in AX can be customised in many ways and one of the more dramatic ones are changes in the background images. The steps are few and goes like this:

Open the Images form

imagesshortcut

 

Create the images in the Images table. In this case we create two. This may vary in your situation

images

Open the Visual profiles form

visualprofileshortcut

Create a visual profile and add the images here

visualprofile

Create a register and device and add the visual profile to the register

register

To get this running on the POS you need to distribute data. Job 1090 should be sufficient. When the data is applied you are ready to enjoy the results:

 

pos1

pos2

This is just the basics of what you can do, but I hope you get the idea of what is possible.

Running the CRT samples on AX7

The RetailSDK delivered with AX7 includes a lot of great sample code making it easier to get things rolling when learning how to customise the solution.

One of the sample projects is the CommerceRuntimeSamples. Before you are able to run it you need to do a couple of tweaks though. If not it will crash and burn with error messages that do point you in the right direction on how to fix it. This blog post is made to safe you some time and getting it fixed without having to go troubleshooting.

The first error that pops up is this one:

operatinguniterror

A configuration error in the Microsoft.Dynamics.Commerce.Runtime.dll. The reason is that it cannot find the right Operation Unit Id. It is specified in the commerceruntime.config and all you have to do is put in the operating id of the channel you would like to work with. In this case I use Houston, which has the id 039:

operating-unit

Next is this error:

storageerror

A storage exception in the same dll and same piece of code. This time we have to look in the app.config file. In here we have a list of connection strings that all point at database names as they appeared in AX 2012 Retail. In AX7 demo servers all data for all channels is in the AxDB database so the fix is to change the database names in the connection strings to AxDB:

catalog-db-name

Now you are able to run the samples and start debugging to learn.

debugactive

 

 

“Invalid package number range” error in AX Retail CDX

I stumbled across the above error running the P-jobs in an AX 2012 R2 installation the other day. It popped up in a test environment and to be honest we had been a bit rough to the message database; but nothing that should mess things up. The reason behind the error was probably a conflict between the current package number and a previously handled package number.

Starting the troubleshoot we quickly realise that there is no number sequence to pull the package numbers from (the package number is added to the records in the message database to identify the messages).

The quick (and dirty) solution was to manually increase the highest package number in both in- and outgoing to a number a certain amount higher. Make sure to mark the records with an error as finished, restart the service and start the distribution from AX again.

The service will now pull the next package number based on the new highest number + 1. If that does not do the trick try increasing the number even more.

 

Added 26th of April 2016:

Here’s a sql script in case you need to do a complete renumbering of the package numbers:

-- Add column for temporary package number
ALTER TABLE IncomingMessages ADD PackageNo2 INT NULL
GO

-- Fill temp package number. In this case start it of by 2000000
DECLARE @id INT
SET @id = 2000000

UPDATE IncomingMessages
SET @id = PackageNo2 = @id + 1
GO

-- Overwrite the package number on the outgoing packages using the old package number as reference
-- Notice: if you start the new numbering too low you can mix up the package numbers on the outgoing table
UPDATE outgoing
SET outgoing.PackageNo = incoming.PackageNo2
FROM OutgoingMessages AS outgoing
INNER JOIN IncomingMessages incoming ON outgoing.packageNo = incoming.PackageNo
GO

-- Update the package number on the incoming messages
UPDATE IncomingMessages
SET PackageNo = PackageNo2
GO

-- Get rid of the temporary column
ALTER TABLE dbo.IncomingMessages
DROP COLUMN PackageNo2
GO
