Loading SAP S/4 HANA Exchange Rates from OANDA Foreign Exchange Rate API through CPI integration

We recently had a requirement to load SAP S/4 HANA Exchange Rate tables from OANDA, one of the leaders in foreign currency exchange arena – https://www.oanda.com/

 

In SAP, exchange rates are stored in the TCURR table and you can use transaction code OB08 to show the maintenance view to the table:

OB08%20Foreign%20exchange%20rate%20transaction%20code

OB08 Foreign exchange rate transaction code

 

TCURR%20table%20maintenance%20view

TCURR table maintenance view

 

Canadian%20dollar%20to%20US%20dollar%20exchange%20rates

Canadian dollar to US dollar exchange rates

 

So now, our requirement is to update this table from the OANDA interface API call.

 

The approach we took here was to implement the ALE distribution model to allow for outbound and inbound integration for exchange rates.  The outbound integration can be used to send the exchange rates from SAP to other SAP systems or other downstream systems.  It also is a way to generate the IDoc to view how it needs to appear for the equivalent inbound process instead of coming up with all of the fields that need to be mapped from scratch.

 

Outbound%20Exchange%20Rate%20model

Outbound Exchange Rate model

 

Exchange%20Rate%20Outbound%20and%20Inbound%20ALE%20model

Exchange Rate Outbound and Inbound ALE model

 

Generate%20Partner%20profile

Outbound%20Exchange%20Rate%20partner%20profile

Outbound Exchange Rate partner profile

 

Outbound%20Exchange%20Rate%20partner%20profile%20details

Outbound Exchange Rate partner profile details

 

So let’s generate an EXCHANGE_RATE IDoc so we can take a look at the IDoc segments and fields:

Here is the call to OANDA:

Here is the IFlow:

OANDA_ExchangeRate_To_SAP%20IFlow

OANDA_ExchangeRate_To_SAP IFlow

 

For now, we just have a timer that executes when we deploy the flow.  This can be scheduled at regular intervals as needed.

 

Here is the Set Dates Groovy script to set the date interval of the OANDA API call:

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
import java.util.Calendar;
import java.util.Date;

def Message processData(Message message) {

//    def yesterday = new Date() - 1
//    message.setProperty("yesterday", yesterday.format("yyyy-MM-dd"))
//    return message


//  Get instance of the calender
    Calendar calendar = Calendar.getInstance();

//  Let's go to last month
    calendar.add(Calendar.MONTH, -1);

//  Get the last date of that month
    int max = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
    
//  Set the calendar to the end of that month    
    calendar.set(Calendar.DAY_OF_MONTH, max);

//  Get the date of the this last day of the month  
    def endOfLastMonth = calendar.getTime();

//  Set this property
    message.setProperty("endOfLastMonth", endOfLastMonth.format("yyyy-MM-dd"))


//  Let's go to month before last month
    calendar.add(Calendar.MONTH, -1);

//  Get the last date of that month
    max = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
    
//  Set the calendar to the end of that month    
    calendar.set(Calendar.DAY_OF_MONTH, max);

//  Get the date of the this last day of the month  
    def endOfLastLastMonth = calendar.getTime();

//  Set this property
    message.setProperty("endOfLastLastMonth", endOfLastMonth.format("yyyy-MM-dd"))


//   Read in the externalized parameter
    def map = message.getProperties();
    def mode = map.get("mode");
    

    def strDateInput;
     
     if (mode.equals("candle")) {
        strInput = "date_time=" + endOfLastMonth.format("yyyy-MM-dd");
        message.setProperty("dateInput", strInput);
     } else if (mode.equals("aggregated")) {
        strInput = "start_time=" + endOfLastLastMonth.format("yyyy-MM-dd") + "&end_time=" + endOfLastMonth.format("yyyy-MM-dd");
        message.setProperty("dateInput",strInput);
         
     } else {
        strInput = "Logic=NotWorking";
        message.setProperty("dateInput", strInput);
     }
    
    return message;
}

 

Here is the HTTP Connection to OANDA:

HTTP%20Connection%20for%20OANDA

HTTP Connection for OANDA

 

Here is the Groovy script to log the OANDA response:

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;

def Message processData(Message message) {

   def body = message.getBody(java.lang.String) as String;
   def messageLog = messageLogFactory.getMessageLog(message);

    //Properties
    def properties = message.getProperties();
    
   String sBody = "OANDA Response XML";


   if(messageLog != null) {
       messageLog.setStringProperty(sBody, body);
       messageLog.addAttachmentAsString(sBody, body, 'text/xml');
    }

   return message;
}

 

Here is the simple graphical mapping of the OANDA response XML to the Exchange Rate IDoc:

OANDA%20Response%20to%20ExchangeRate%20IDoc%20Mapping

OANDA Response to ExchangeRate IDoc Mapping

 

OANDA%20Response%20to%20ExchangeRate%20IDoc%20Mapping%20continued

OANDA Response to ExchangeRate IDoc Mapping continued

 

Here is the Groovy script to log the mapped Exchange rate IDoc:

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;

def Message processData(Message message) {

   def body = message.getBody(java.lang.String) as String;
   def messageLog = messageLogFactory.getMessageLog(message);

    //Properties
    def properties = message.getProperties();
    
   String sBody = "ExchangeRate IDoc for S4 HANA";


   if(messageLog != null) {
       messageLog.setStringProperty(sBody, body);
       messageLog.addAttachmentAsString(sBody, body, 'text/xml');
    }

   return message;
}

So here is the execution of the IFlow with the OANDA response and mapped IDoc captured as attachments:

So to summarize, in this example CPI triggers the OANDA exchange rate API call and maps the response data to the Exchange rate IDoc and send this to SAP to update the TCURR table.

I hope that comes in handy to you if you are trying to implement a CPI interface that calls an external foreign exchange rate API but not necessarily OANDA, and map this back to SAP format and send this to SAP S/4 HANA system.  We also investigated the SOAP approach but we only see the outbound SOAP async ExchangeRateMasterDataReplicationBundleRequest_Out and not an equivalent inbound SOAP async message.

 

Here you can see the outbound exchange rate

SAP%20API%20Hub%20Exchange%20Rate%20Outbound

SAP API Hub Exchange Rate Outbound

 

However, there does not appear to be an inbound asynchronous service exposed through the API Hub at this point but hopefully that will be added soon.  But the IDoc approach works really well.

 

See you at the next blog…

 

Thanks,

Jay
