SAP PI REST Polling scenario

PI REST Adapter - Polling a REST API

 

 

We would like to frequently poll hiring information from REST API

 

 

We have two options in REST Adapter polling in SAP PO:

Option 1: Incremental request based on timestamp of last call

Option 2: Incremental request based on response content

 

 

Can we combine these two options

 

Is there any custom way of handling below HTTP polling scenario. I am trying to get candidates from a Recruiting system and I need to pass below values in URL:

 

https://api.jv.com/api/v2/candidate?api=<key>&sc=<secret>&format=json &start=1&count=50&datestart=2016-04-25&dateend=2016-04-26

 

1. So my variables are "start" which would the next starting index i.e. 1...51...101

 

2. datestart would be the last time I ran this interface

 

3. dateend would be current time.

 

I tried the incremental count approach but how do we handle both incremental date and nextPageToken ?

 

Also if I use next Pagetoken the API response doesn't carry a page index or current page and next page token.

RFC adapter Response Junk characters

Hi,

 

We are facing a strange issue in the scenario FILE-->PI<-->RFC( Async Sync scenario).

                                                                   FILE<--PI    

 

We are getting Junk response from SAP RFC sometimes, when we send the same request after some time it works fine means getting proper response. Some times it works first request itself some time we keep on trying until we get the valid response. 

 

I thought of code page error, but if that is the case we shouldn't get the valid response when we try next time with the same request.

 

ABAPer debugged the code and he is saying that no issues in the code. Could any one please suggest how can I trace this error whether this issue is at ECC side or at PI side?

 

Thanks,

Need help regarding HTTPS with AS2 setup !!

Hi All,

 

We have a scenario wherein we are communicating with Bank using Seeburger AS2 with HTTPS while sending data.

 

We have sent them our certificate chain having our public certificate in .p7b format and vice-verse they have sent their 3 chained SSL certificate in .cer format.

 

Now, the issue is that when we use HTTPS with AS2, we have 2 additional fields to be filled.

 

 

So,

 

1. I am not sure what needs to filled in these fields.

2. The received SSL certificate chain needs to installed individually in NWA or as one only

3. The location of SSL certificates in NWA. Which view should i use?

4. Is there any other setting to use SSL connection. We already have 443 SSL port enabled and in green status.

 

I believe once this SSL handshake is successful, the the role of AS2 certificate will come into play.

 

Please suggest.

 

Thanks

Map an undefined node

Hi Gurus,

I'm not sure if this is at all possible. Is it possible to map a node + fields that are not defined in the external definition imported in PI?

For example:

the source file has:

<source>

  <name>BOB</name>

  <***>F</***>

  <contact>

    <telephone>1111111</telephone>

    <mobile>2222222</mobile>

    <email>aaa@aaa.com</email>

  </contact>

</source>

 

But in PI structure (ext def), it's only:

<source>

   <name>

   <***>

<source>

 

Is there a way to map the source node contact to the target structure even if it was not declared in PI? Can it be done using UDF or XSLT mapping?

In the download site for SAP NWDS 7.5 the Windows version is mentioned as Win32 (Support Packages and Patches --> SAP NetWeaver and complementary products --> SAP NetWeaver --> SAP NetWeaver 7.5 --> Developer Studio.) - however no mention of a 64 bit NWDS version for download.

 

However, the JDK version and OS versions all have a pre requisite for 64 bit versions - is there any separate location to download the 64 bit NWDS ?

Hello Gurus,

 

We have a scenario where 2 files were placed at the interval of 15 mins each. For eg . say one file was placed at 12.15 PM and and other At 12.30 PM. QOS is EO for the file channel. The thing what we have observed is PI is picking the file placed at 12.30 PM and then picking the file placed at 12.15 PM later. I can say that first file size not so large when compared to 2nd one. the files are not picking up in the same sequence .Any specific reason why this thing happened ?? .I appreciate your help on this.

<DOB>1992-09-25</DOB>

Hello,

 

 

We have to post multiple address records from SAP to a 3rd party REST service.We are on PO 7.5.

We are using ABAP PROXY to PI to REST interface.

 

I have created data type with Address element with has 0-n occurrence. This has been assigned to message type MT_ADDRESS.

XML to JSON conversion on REST adapter has been used to convert input XML to JSON.

 

With this setting, below JSON is being sent to REST service.

 

 

{"Address":[

{"code":"POST1","name":"Test POS Address 1","erpId":"POST1","line1":"Address 1 Line 1","line2":"Address 1 Line 2","city":"City1","state":"MA","zip":19501,"country":"US","shipTo":true,"billTo":true,"invoiceTo":true},

{"code":"POST2","name":"Test POS Address 2","erpId":"POST2","line1":"Address 2 Line 1","line2":"Address 2 Line 2","city":"City2","state":"MA","zip":19502,"country":"US","shipTo":true,"billTo":true,"invoiceTo":true}

]}

 

 

Expected format :

 

[

{"code":"POST1","name":"Test POS Address 1","erpId":"POST1","line1":"Address 1 Line 1","line2":"Address 1 Line 2","city":"City1","state":"MA","zip":19501,"country":"US","shipTo":true,"billTo":true,"invoiceTo":true},

{"code":"POST2","name":"Test POS Address 2","erpId":"POST2","line1":"Address 2 Line 1","line2":"Address 2 Line 2","city":"City2","state":"MA","zip":19502,"country":"US","shipTo":true,"billTo":true,"invoiceTo":true}

]

 

 

My message type is MT_ADDRESS which has been stripped already due to setting "strip the outer element".

But I am not able find a way to strip the "Address" tag?

 

 

Please help?

Hi SDNites,

 

I have populated XML is Content modifier and connected this step with the message mapping. It gets deployed with error and have obtained the below message,

 

Content Modifier may not pass Xml message to Message Mapping. Message Mapping supports Xml input only.

 

Also it is deployed but I cannot see in the monitoring so I believe it because of the message mentioned above. Can you please guide how can I resolve the above.

design Query?

Hello All,

I am working on a requirement and need your inputs to best design and implement it, here is the scenario.

SAP HANA ->SAP PI 7.4(Java Single Stack)-> Third Part Messaging System and vice versa.

 

Scenario: SAP will trigger email message (Email Id, Subject, Email Body) via outbound SAP proxy, which will come to SAP PI and will be send to3rd party messaging system using Rest adapter. Once SAP message is acknowledged for processing by 3rd party messaging system than it will return me unique message id for each of the email message in a field called location.

 

Please refer screenshot for the API below.

Response Example

The following code is an example response from a successful message sendout.

 

view sourceprint?

 

 

1HTTP 1.1 202 Accepted

 

 

2Location: http://api.whispir.com/messages/ABD435DBFCD663DEDEFF?apikey=<yourkey>

 

 

3

 

 

4Your message has been accepted forprocessing.

 

 

 

 

This message id than needs to be used again to query the third party system for the status of each Email message (delivered, failed etc).

 

  1. Considering I need to receive the message id and then use it to query again the third party system
  2. Do I need to have separate interface to query the status? Meaning first time the message will come from SAP to PI and then to 3rd party system. The message id will be stored in SAP R/3 . Then another proxy will take the message id and through PI will query again the 3rd party system through a new interface.
  3. What is the best way to retrieve and store the message id from field location and how can it be done? I mean should I use synchronous service interface at SAP end and 3rd party system or it can be done in better way?
  4. What is the use of tab “HTTP Header” and “Response determination” in REST adapter?

 

Please let me know if you need more details from my end.

Thanks/Ajay
