Error "Element EX_FUNCTIONS of container metadata RFC_METADATA_GET unknown" was not solved

While executing the BAPI “ACC_DOCUMENT_POS” using the SRC component, the following error appears and execution stops.

I thought it was a connector problem, so I downloaded the installer for “SAP Connector for Microsoft .NET 3.0.25.0 for Windows 32bit” from the site below and updated it, but the error still persists.

When I checked the error content, I found the same error, so I thought that the connector had not been updated, so I tried to install it again, but the error content was the same and it was not resolved.

Can someone please tell me how to fix the error?

Dear,Secco EWB

I solved this problem.

The error was caused by the latest connector not being properly installed.

The solution is as follows.
①Check if the “sapnco.dill” and “sapnco_utils.dill” files in the local folder “sapnco” are updated.
→ right click on the file > select properties > click on the details tab

②Compared with the latest connector information, if the “File version” item in the details tab does not match, uninstall the currently existing “sapnco.dill” and “sapnco_utils.dill”, Install the connector for

③Delete “sapnco.dill” in “sapnco” in the UiPath BAPI package directory and replace it with the latest “sapnco.dill” and “sapnco_utils.dill” installed locally.

Try it here.

Best regards,
Kunimoto
