Accessing SAP Business One using the Service Layer is a two-step process. The first step (Login) responds with two cookies. These cookies are then used in any subsequent web service calls in the current processing cycle.

The difference in Bizweaver v2.5 is that a Service Layer global connection can be used to manage much of the detail work. Configuring a Service Layer global connection is described here.

• Select SAP Service Layer in the “Select Service” drop-down list.
• Select Authenticate in the next drop-down to the right.
• Select the Authentication Required checkbox.
• Select your previously defined Service Layer connection in the “Select Connection” drop-down.
• Click the Validate Login link to confirm that your connection is working. If the response is not True, check your connection information and try again.

Once the workflow has completed a successful login, the remaining steps will use the Interact With Data option.

• Select SAP Service Layer in the “Select Service” drop-down list.
• Select Interact With Data in the next drop-down to the right.
