Couldn't Update integration service Error: Could not load file or assembly "Interop.SAPbobsCOM.dll, Version=10.0"
Product Version:
iVend Retail 6.6
SAP Business One 9.3 (HANA)
Problem Statement:
The customer encountered the following error while configuring the integration service:
"Could not load file or assembly 'Interop.SAPbobsCOM.dll, Version=10.0'"
Scenario Overview:
1) Customer is using SAP B1 HANA version 9.3 and iVend Retail 6.6
2) Version_10 folder (Interop.SAPbobsCOM.dll file was available in Version_10 folder) was available in integration folder and Configuration folder (if SAP is 10.0, then this is required); below is the screenshot for the same
Troubleshooting:
Reinstallation of SAP DI API:
Both 32-bit and 64-bit DI API components were reinstalled from the SAP setup folder on both the SAP server and the integration server.
The issue persisted.
DLL Re-registration:
The SAPbobsCOM100.dll was re-registered manually, but no resolution was achieved.
Proposed Solution :
A new integration executable (EXE) and updated configuration file were provided to the customer.
Upon deploying these, the integration service was successfully updated and started without errors.
Additional Issue Encountered:
"SAP Business One connection error: Login SLD Failed.
Make sure the server, company, and user credentials are correct."
Actions Taken:
User Permissions:
Verified SAP B1 user permissions in License Administration.
Necessary updates were made, but the issue persisted.
SLD Accessibility:
Access to SAP Control Center confirmed that the SLD (System Landscape Directory) was reachable.
However, the CXSiVend user was not recognized.
Password Update:
Guided the customer to update the CXSiVend user's password via:
Administration → Setup → General → Users
Post update, the integration service details were refreshed and the error was resolved.
Constraints/Scenarios to Consider:
DLL version mismatch: iVend 6.6 expects version 9.x DLLs; version 10.0 may cause compatibility issues unless explicitly supported.
Correct file placement: Ensure that the correct version of Interop.SAPbobsCOM.dll is in both the Integration and Configuration folders.
User credentials in SLD: Always validate that the integration user is present and the credentials are up to date.
64-bit vs 32-bit Conflicts: Ensure consistency in component architecture across SAP and integration environments.
