+# Troubleshoot Commerce Data Exchange (CDX)
+
+This article explains how to troubleshoot errors for Commerce Data Exchange (CDX) in Microsoft Dynamics 365 Commerce environments.
+
+## Issue 1: Error due to batch statuses
+
+### Symptoms
+
+You receive the following error message: 
+
+`System.ArgumentNullException: Value cannot be null. Parameter name: connectionString at Microsoft.Dynamics.Retail.CommerceDataExchange.SqlTargetRequestHandler.`
+
+#### Root cause
+
+An error has occurred because of batch job statuses. You can view the error in a failed download job on the **Download sessions** page.
+
+### Resolution
+
+In Dynamics 365 Commerce headquarters, go to **System administration** \> **Inquiries** \> **Batch jobs**, find the data writing batch associated with the Commerce Scale Unit to which the download job is supposed to be applied, and change the batch job's status to **Withhold**.
+
+## Issue 2: Can't execute Run now command from Distribution schedule page unless batch processing is used
+
+### Symptoms
+
+You can't perform the **Run now** command from the **Distribution schedule** page unless batch processing is used.
+
+#### Root cause
+
+This change was intentionally made in Commerce version 10.0.11 because of performance issues that occur if jobs are run during times when environments are most heavily used. In another change that was made as part of this feature enhancement, recurrence can't be used when the **Full data sync** (full job synchronization) command is run from the **Channel database** page in Commerce headquarters. Only a single occurrence can be run.
+
+### Resolution
+
+Microsoft doesn't recommend that you change this behavior. However, if you're in a development environment, you can change it in Commerce headquarters by going to **Commerce shared parameters** \> **Configuration parameters** and setting a new name, CDX_DISABLE_FORCESCHEDULEINBATCH, that has a value of 1.
+
+## Issue 3: Error due to extended table length
+
+### Symptoms
+
+You receive the following error message: 
+
+`Microsoft.Dynamics.Retail.CommerceDataExchange.SqlWriteRequestRunException: Failed to run SqlWriteRequestRunner for table AX.\
.`
+
+#### Root cause
+
+An error has occurred because the length of one or more DBO tables has been extended, so that truncation of data is required. Therefore, a truncation failure has occurred. 
+
+### Resolution
+
+Generate a Microsoft Support request. 
+
+For information on best practices, see [Enable custom Commerce Data Exchange synchronization via extension](/dynamics365/commerce/dev-itpro/cdx-extensibility). These best practices include removing the extended data type (EDT) extension on the table field that's being edited and using the CDX extension table to store the long (full) value that's required.
+
+## Issue 4: Error due to download session failure
+
+### Symptoms
+
+The download session fails, and the error message states "...tried too many times."
+
+### Resolution
+
+In Commerce headquarters, go to **Retail and Commerce** \> **Headquarters setup** \> **Parameters** \> **Commerce scheduler parameters** and set the **Try count** field to **3**. If the value of this field is too high, download sessions might fail during high-usage times. After you complete this step, the job sets its status to **Canceled** and stops retrying itself. Learn more at [Commerce Data Exchange best practices](/dynamics365/commerce/dev-itpro/cdx-best-practices).
+
+## Issue 5: Unable to cancel a running CDX job
+
+### Symptoms
+
+You can't cancel a running CDX job.
+
+### Resolution
+
+- If this issue occurs in a production environment, sign in to [Microsoft Dynamics Lifecycle Services (LCS)[(https://lcs.dynamics.com/Logon/Index), and create a request for immediate support.
+- If the issue occurs in a nonproduction environment, create a Microsoft Support request.
+
+## Issue 6: Slow download sessions after adding multiple POS terminals
+
+### Symptoms
+
+After you add multiple POS terminals, download sessions take a long time, or you experience overall slowness in Commerce headquarters.
+
+#### Root cause
+
+When you create a new Store Commerce app offline database and add it to the relevant channel database group, it inherits all existing download sessions since the last full database synchronization occurred. Even under normal conditions, the exceptional data generation that might occur can be too large and affect performance. At the busiest times, it can severely impair the environment's performance.
+
+### Resolution
+
+Microsoft recommends that you have either:
+
+- A "dummy" channel database group (that is, a group that isn't associated with any distribution schedule job) that you assign to the newly generated terminals.
+- A special offline profile where the **Pause offline synchronization** option is set to **Yes**. In this way, data generation can occur when it's required and when the system is most available to do it. However, the system might pause multiple times as required. If it's too late to use this approach, create a Microsoft Support request.
+
+## Issue 7: Incremental (delta) data synchronization takes too long
+
+### Symptoms
+
+Normal, incremental (delta) data synchronization takes too long, even though the number of affected rows is small.
+
+#### Root cause
+
+This issue can occur when a new channel (store) is created, because all the data must be recreated for the new store.
+
+### Resolution
+
+Microsoft recommends that you have a "dummy" channel database that's associated with a "dummy" channel database group, and that you assign it to the newly generated channel (store). In this way, data generation can occur when required and the system is most available to do it. If it's too late to use this approach, create a Microsoft Support request.
+
+## Issue 8: P-job error due to violation of primary key restraint 
+
+### Symptoms
+
+The P-job fails to create an upload session, and you receive the following error message: 
+
+`System.Data.SqlClient.SqlException (0x80131904): Violation of PRIMARY KEY constraint 'PK\_UPLOADSESSION'. Cannot insert duplicate key in object 'crt.UPLOADSESSION'.`
+
+### Resolution
+
+- If the issue occurs in a production environment, sign in to [Microsoft Dynamics Lifecycle Services (LCS)[(https://lcs.dynamics.com/Logon/Index), and create a request for immediate support.
+- If the issue occurs in a nonproduction environment, create a Microsoft Support request.
+
+## Issue 9: Session package download error due to record not found
+
+### Symptoms
+
+When you try to download an upload session package from the **Upload sessions** page in Commerce headquarters, you receive the following error message: 
+
+`Record for Id - \ not found.`
+
+### Resolution
+
+Create a Microsoft Support request.
+
+## Issue 10: Error due to CDX download sessions failing to be applied
+
+### Symptoms
+
+CDX download sessions fail to be applied, and you receive the following error message: 
+
+`Failed to get download session package URI.`
+
+### Resolution
+
+- If the issue occurs in a production environment, sign in to [Microsoft Dynamics Lifecycle Services (LCS)[(https://lcs.dynamics.com/Logon/Index), and create a request for immediate support.
+- If the issue occurs in a nonproduction environment, create a Microsoft Support request.
+
+## Issue 11: No download sessions are applied, and no upload sessions are created
+
+### Symptoms
+
+No download sessions are applied, and no upload sessions are created.
+
+### Resolution
+
+- If the issue occurs in a production environment, sign in to [Microsoft Dynamics Lifecycle Services (LCS)[(https://lcs.dynamics.com/Logon/Index), and create a request for immediate support.
+- If the issue occurs in a nonproduction environment, create a Microsoft Support request.
+
+## Issue 12: Upload sessions error due to multiple records in the RetailListingStatusLog table
+
+### Symptoms
+
+Upload sessions fail, and you receive the following error message: 
+
+`Infolog for task Default:P-0001 (...) Error when bulk inserting data. Target table: RetailListingStatusLog.`
+
+#### Root cause
+
+An error has occurred because the upload session package contains multiple records in the **RetailListingStatusLog** table. These records have the same **StatusDateTime** value between two or more records.
+
+### Resolution
+
+- If the issue occurs in a production environment, sign in to [Microsoft Dynamics Lifecycle Services (LCS)[(https://lcs.dynamics.com/Logon/Index), and create a request for immediate support.
+- If the issue occurs in a nonproduction environment, create a Microsoft Support request.
+
+## Issue 13: Failure during switch to offline mode
+
+### Symptoms
+
+When a cashier tries to switch to offline mode or is forced offline, the switch fails.
+
+#### Root cause
+
+There are many possible causes for the failure. First, verify basic information: Does the computer have available hard drive space? If you're using SQL Server Express, is the size of the offline database at the 10 gigabytes (GB) limit? Are there pending download sessions for the register? Pending download sessions indicate that the register is no longer up to date. Therefore, offline switching might temporarily be prevented.
+
+### Resolution
+
+Microsoft recommends that you contact Microsoft Support.
+
+- If the issue occurs in a production environment, sign in to [Microsoft Dynamics Lifecycle Services (LCS)[(https://lcs.dynamics.com/Logon/Index), and create a request for immediate support.
+- If the issue occurs in a nonproduction environment, create a Microsoft Support request.

+# Dynamics 365 Payment Connector for Adyen - Invoicing sales orders fail due to stale authorization
+
+This article provides a solution for an issue with the Dynamics 365 Payment Connector for Adyen where invoicing sales orders fail due to stale authorization.
+
+## Symptoms
+
+Invoicing sales orders fail and generate the error `Exception has been thrown by the target of an invocation. System.ArgumentNullException: Value cannot be null.`. The underlying error in the logs is `The following error occurred during the capture call - Dynamics 365 Payment Connector for Adyen: Error code Decline message Capture failed due to stale authorization.`.
+
+### Root cause
+
+This error happens when an authorization older than the **Authorization stale period (days)** property value is sent to the payment connector for capture.
+
+## Resolution
+
+To solve this issue, follow these steps.
+
+1. In Dynamics 365 Commerce headquarters, go to **Accounts receivable parameters** \> **Credit Card**.
+1. In the **Number of days before expired** field, ensure that the value is set to one (1) day less than the value set in merchant properties for all channels. The recommended value for **Authorization stale period (days)** is 14 in Adyen merchant properties, and 13 in **Accounts receivables parameters**.
+1. Retry invoicing.

+# Dynamics 365 Payment Connector for Adyen - EFT Terminal ID isn't set
+
+This article provides a solution for an issue with the Dynamics 365 Payment Connector for Adyen where the payment authorization calls fail, and a hardware error occurs because the electronic funds transfer (EFT) Terminal ID isn't set.
+
+## Symptoms
+
+Payment authorization calls fail, and a hardware error occurs. An error message in the event log indicates that the **EFT Terminal ID** value isn't set.
+
+### Root cause
+
+This issue can occur when the **EFT POS Register Number** field isn't set on the register or the IIS Hardware Station. It can also occur if the value is set but isn't correctly synced to the POS terminal, or when the value is cached.
+
+## Resolution
+
+To solve this issue, follow these steps.
+
+1. Follow the instructions in [Set up a Dynamics 365 register](/dynamics365/commerce/dev-itpro/adyen-connector-setup#set-up-a-dynamics-365-register).
+1. Run the 1070 and 1090 distribution schedule jobs.
+1. If the issue isn't resolved, consider reactivating the Store Commerce app, because the value of the **EFT POS Register Number** field may be cached and might need to be reset.
