SAP Business One Integration Tool – Troubleshooting Guide

Understanding Troubleshooting in SAP Business One

Before diving into specific errors, it’s important to understand how SAP B1 issues are typically classified. Most SAP error troubleshooting scenarios fall into one of the following categories:

• Global configuration errors
• Step configuration errors
• Runtime errors

Identifying the correct category helps narrow down the root cause more quickly and avoids unnecessary changes within the system.

SAP Business One Troubleshooting – Global Configuration Errors

Global configuration errors usually occur during the initial setup or while configuring integrations for a specific environment. These issues are often linked to system versions, server settings or incorrect administrative configurations.

1. Failed to Connect to DI API Server (OBServerDLL Version Mismatch)

This error indicates a version conflict between system components required for SAP Business One integrations.

Error Description:

Failed to connect to DI API Server. OBServerDLL.dll version is older than the DI API version.

Cause:

This occurs when the SBOCommon database version does not match the company database version.

Solution:

Reinstall the correct version of the SAP Business One Integration API to ensure compatibility across all components.

2. Unable to Initialise OBServerDLL.dll

This issue typically points to an incorrect licensing configuration rather than a system fault.

Error Description:

Failed to connect to DI API Server. Unable to initialise OBServerDLL.dll.

Cause:

Incorrect SAP licence server details entered during configuration.

Solution:

Verify the licence server hostname and port number in the integration tool and confirm they match the SAP installation.

3. Failed to Load Company List from Server (COM Class Error)

This error occurs when the integration tool architecture does not match the installed DI API.

Error Description:

Failed to load company list due to missing module (Error 8007007e).

Cause:

Older versions of the integration tool only support 32-bit APIs.

Solution:

Install the 32-bit DI API or upgrade the integration tool to a newer version that supports both 32-bit and 64-bit environments.

4. Failed to Connect to SLD Using ‘localhost’

Using ‘localhost’ can prevent SAP Business One from locating the correct backend services, especially in distributed or production environments.

Error Description:

Failed to connect or log on to SLD.

Cause:

Using ‘localhost’ instead of the actual database server hostname.

Solution:

Replace ‘localhost’ with the correct database server name in the configuration.

5. SLD Configuration or Availability Issue

When the System Landscape Directory is misconfigured or temporarily unavailable, SAP Business One cannot validate system connections or retrieve landscape details.

Cause:

The System Landscape Directory (SLD) is misconfigured or offline.

Solution:

Contact your SAP partner to verify and restore the SLD configuration.

SAP Business One Troubleshooting – Step Configuration Errors

Step configuration errors occur while setting up or executing specific integration steps.

Unable to Get Object Schema – Not Connected to a Company

Cause:

The user is not properly configured under authentication settings or does not have a valid SAP licence.

Solution:

Go to SAP Business One Administration > Licence Administration and assign an active licence to the user.

This is a common issue during integrations such as SAP B1 connect or third-party platform mappings.

SAP Business One Troubleshooting – Runtime Errors

Runtime errors occur when the system cannot complete a task and stops execution.

1. Numbering Series Not Defined (-5002)

This error occurs when SAP Business One cannot assign a document number because the selected numbering series does not support the document type being created.

Cause:

An unsupported numbering series is mapped to the document type.

Solution:

Use a valid numbering series or leave the field unmapped to allow SAP B1 to assign the default series.

2. Date Deviates from Permissible Range

This issue arises when the document date or due date falls outside the active posting period. It is commonly seen with A/R and A/P invoices.

Cause:

Posting period restrictions for A/R or A/P invoices.

Solution:

Update posting periods under the SAP Business One administration module and set valid document dates.

3. XML Validation Error Against Schema

This error indicates that the input data does not match the expected XML schema structure.

Cause:

An incorrect or outdated schema in the database query step.

Solution:

Open the query, make a minor change such as adding a space, and re-execute it to refresh the schema.

4. Metadata Service File Missing

This runtime error occurs when SAP Business One cannot load the required metadata for a selected operation.

Cause:

Missing or outdated operation metadata.

Solution:

Reopen the step, reselect the operation, and refresh the metadata.

5. Not Connected to a Company During Operation

This error appears when the user executing the process does not have a valid SAP Business One licence or is not correctly linked to a company database.

Cause:

User licence is missing or expired.

Solution:

Assign a valid licence through SAP Business One administration settings.

6. Error Code 998 – DI API in Inconsistent State

This error occurs when the DI API component becomes unstable due to a failed or incomplete transaction.

Cause:

The DI API component is stuck because of failed object handling.

Solution:

Restart the SAP Business One Integration Agent service to release the object.

Additional Considerations for Modern SAP B1 Environments

As SAP Business One environments become more connected and data-heavy, teams must also consider performance, monitoring and integration-related aspects beyond basic troubleshooting.

1. SAP Business One Slow Performance

Performance issues can arise due to large databases, high transaction volumes, heavy integrations or poorly optimised add-ons. Regular performance monitoring, database maintenance and periodic review of active integrations can help reduce delays and improve system responsiveness.

2. Stripe SAP Business One Integration

When using Stripe SAP Business One integration, ensure that API versions are up to date and authentication tokens remain valid. This helps prevent transaction synchronisation failures and data inconsistencies.

3. Exception Handling and Monitoring

Using SAP Business One exception management software helps identify recurring failures, integration bottlenecks and system inconsistencies early, before they affect business operations.
