This step is to configure three Assign activities to:
Set the header details.
Note: You need to populate certain variables in the BPEL process for ServiceBean_Header elements to pass values that may be required to embed applications context into SOAP envelopes for Web service authorization. These ServiceBean_Header elements for Business Service Object interface type are RESPONSIBILITY_NAME, RESPONSIBILITY_APPL_NAME, SECURITY_GROUP_NAME, NLS_LANGUAGE, and ORG_ID.
Detailed information on how to set ServiceBean_Header for the SOAP request, see Assigning ServiceBean_Header Parameters.
Pass the purchase order details read from the File Adapter as an input to the second Invoke activity for PurchaseOrderService partner link.
Pass single purchase order approval information to the requestor through the dummy Reply activity.
To add the first Assign activity to pass header details:
Assigning ServiceBean_Header Parameters:
In Oracle JDeveloper, expand the BPEL Constructs from the Component Palette. Drag and drop the Assign activity into the center swim lane of the process diagram between the two Invoke activities you just created earlier.
Double-click the Assign activity to access the Edit Assign dialog box.
Click the General tab to enter the name for the Assign activity, such as 'SetServiceBeanHeader'.
Select the Copy Rules tab and expand the target trees:
Click the Expression icon to invoke the Expression Builder dialog.
Enter 'Purchasing, Vision Operations (USA)' in the Expression box. Click OK. The Expression icon with the expression value appears in the center of the Edit Assign dialog, between the From and To navigation tree nodes.
In the To navigation tree, navigate to Variables > Process > Variables > InvokePurchaseOrderService_PurchaseOrderService_ApprovePurchaseOrder_InputVariable > header> ns5:ServiceBean_Header and select ns5:RESPONSIBILITY_NAME.
Drag the Expression icon to connect to the target node (ns5:RESPONSIBILITY_NAME) that you just identified. This creates a line that connects the source and target nodes. The copy rule is displayed in the From and To sections at the bottom of the Edit Assign dialog box.
Enter second pair of parameters by clicking the Expression icon to invoke the Expression Builder dialog.
Enter 'PUR' in the Expression box. Click OK. The Expression icon with the expression value ('PUR') appears in the center of the Edit Assign dialog, between the From and To navigation tree nodes.
In the To navigation tree, navigate to Variables > Process > Variables > InvokePurchaseOrderService_PurchaseOrderService_ApprovePurchaseOrder_InputVariable > header> ns5:ServiceBean_Header and select ns5:RESPONSIBILITY_APPL_NAME.
Drag the Expression icon to connect to the target node (ns5:RESPONSIBILITY_APPL_NAME) that you just identified. This creates a line that connects the source and target nodes. The copy rule is displayed in the From and To sections at the bottom of the Edit Assign dialog box.
Enter third pair of parameters by clicking the Expression icon to invoke the Expression Builder dialog.
Enter 'STANDARD' in the Expression box. Click OK. The Expression icon with the expression value ('STANDARD') appears in the center of the Edit Assign dialog, between the From and To navigation tree nodes.
In the To navigation tree, navigate to Variables > Process > Variables > InvokePurchaseOrderService_PurchaseOrderService_ApprovePurchaseOrder_InputVariable > header> ns5:ServiceBean_Header and select ns5:SECURITY_GROUP_NAME.
Drag the Expression icon to connect to the target node (ns5:SECURITY_GROUP_NAME) that you just identified. This creates a line that connects the source and target nodes. The copy rule is displayed in the From and To sections at the bottom of the Edit Assign dialog box.
Enter the fourth pair of parameters by clicking the Expression icon to invoke the Expression Builder dialog.
Enter 'AMERICAN' in the Expression box. Click OK. The Expression icon with the expression value ('AMERICAN') appears in the center of the Edit Assign dialog, between the From and To navigation tree nodes.
In the To navigation tree, navigate to Variables > Process > Variables > InvokePurchaseOrderService_PurchaseOrderService_ApprovePurchaseOrder_InputVariable > header> ns5:ServiceBean_Header and select ns5:NLS_LANGUAGE.
Drag the Expression icon to connect to the target node (ns5:NLS_LANGUAGE) that you just identified. This creates a line that connects the source and target nodes. The copy rule is displayed in the From and To sections at the bottom of the Edit Assign dialog box.
Enter the fifth pair of parameters by clicking the Expression icon to invoke the Expression Builder dialog.
Enter '204' in the Expression box. Click OK. The Expression icon with the expression value ('204') appears in the center of the Edit Assign dialog, between the From and To navigation tree nodes.
In the To navigation tree, navigate to Variables > Process > Variables > InvokePurchaseOrderService_PurchaseOrderService_ApprovePurchaseOrder_InputVariable > header> ns5:ServiceBean_Header and select ns5:ORG_ID.
Drag the Expression icon to connect to the target node (ns5:ORG_ID) that you just identified. This creates a line that connects the source and target nodes. The copy rule is displayed in the From and To sections at the bottom of the Edit Assign dialog box.
Click Apply and then OK to complete the configuration of the Assign activity.
To enter the second Assign activity to pass PO details to the InvokePOService Invoke activity:
In Oracle JDeveloper BPEL Designer, drag and drop the second Assign activity from the BPEL Constructs into the center swim lane of the process diagram, between the first Assign and Invoke activities.
Double-click the Assign activity to access the Edit Assign dialog box.
Click the General tab to enter the name for the Assign activity, such as 'SetPOApproval'.
Select the Copy Rules tab and expand the target trees:
In the From navigation tree, navigate to Variables > Process > Variables > InvokeReadPO_SynchRead_OutputVariable > PurchaseOrderService_ApprovePurchaseOrder > body > ns6:PurchaseOrderService_ApprovePurchaseOrder and select poNumber.
In the To navigation tree, navigate to Variables > Process > Variables > InvokePurchaseOrderService_PurchaseOrderService_ApprovePurchaseOrder_InputVariable > body > ns6:PurchaseOrderService_ApprovePurchaseOrder and select poNumber.
Drag the source node (poNumber) to connect to the target node (poNumber) that you just identified. This creates a line that connects the source and target nodes. The copy rule is displayed in the From and To sections at the bottom of the Edit Assign dialog box.
Click Apply and then OK to complete the configuration of the Assign activity.
To enter the third Assign activity to set the SOAP response to output:
Add the third Assign activity by dragging and dropping the Assign activity into the center swim lane of the process diagram, between the InvokePOService Invoke and the Replyoutput activities.
Repeat Step 2 to Step 3 described in creating the first Assign activity to add the second Assign activity called 'SetPOStatus'.
Select the Copy Rules tab and expand the source and target trees:
In the From navigation tree, navigate to Variables > Process > Variables > InvokePurchaseOrderService_PurchaseOrderService_ApprovePurchaseOrder_OutputVariable and select body.
In the To navigation tree, navigate to Variables > Process > Variables > outputVariable and select payload.
Drag the source node (body) to connect to the target node (payload) that you just identified. This creates a line that connects the source and target nodes. The copy rule is displayed in the From and To sections at the bottom of the Edit Assign dialog box.
Click Apply and then OK to complete the configuration of the Assign activity.
