LoadRunner failed to record file upload in SAPGUI protocol

Hi, 

I am using LR v12.02, SAP GUI protocol on SAP desktop client v730, SAP server ECC6. 

I've run into an issue where LR fails to record the action to upload file in SAP Windows desktop client. I've searched online and did not find much help on this topic. Any suggestions are welcome. 

I am attaching a document via FV50 using the button available in the document title, then Create > Create Attachment which launches a windows dialogue box to navigate to the required file. LR fails to record anyting from the Import File dialog windows. 

Below is the sample script from recording. As you can see the first part is selecting Create attachment from the menu. The second part captures the text in the status bar. There is nothing inbetween about specifying the file to upload. 

    sapgui_toolbar_select_context_menu_item_by_text("Create...|Create Attachment", 
        shell2, 
        "Create...|Create Attachment", 
        BEGIN_OPTIONAL, 
            "AdditionalInfo=sapgui4041", 
        END_OPTIONAL);

    sapgui_status_bar_get_text("paramStatusBarText", 
        BEGIN_OPTIONAL, 
            "Recorded status bar text: The attachment was successfully created", 
            "AdditionalInfo=sapgui4044", 
        END_OPTIONAL);
