FCC - Drill Through to SAP URL parameters

Summary:

The client has provided a custom SAP URL for us to set up a Drill Through feature. During the configuration, I replace the placeholders for "Account" and "Entity" in the URL with their corresponding source column names in the workbench (the same as in the Import Format). However, when I perform a drill-through on a value, it successfully directs me to SAP, but the values do not transfer correctly.

this is the doc I used:

this is how I currently have the section of the URL set: /sap/bc/gui/sap/its/webgui/?SD_SAKNR-LOW=$Account Number$;SD_BUKRS-LOW=$Company Code$;
