The URL filter parameter of OData gets automatically truncated to 4 chars

February 18, 2016, 12:32 pm

hi,

I've observed this strange behavior in our system before as well. but then it got resolved automatically.

But now it is back.


Let me explain the problem:

I invoke the OData get service in a browser and pass a filter parameter. But when this call reaches my Data Provider Class, the URL filter parameter that I'd specified in the URL gets truncated to 4 characters.

 

Eg: I invoke URL https://<server>/sap/opu/odata/UI2/PAGE_BUILDER_CONF/Catalogs?$filter=type%20eq%20%27CATALOG_PAGE%27

But when this call reaches my DPC, the IT_FILTER_SELECT_OPTIONS has this filter, but the value is truncated to 4 chars. So it has I EQ CATA instead of I EQ CATALOG_PAGE.

I've tried clearing all the model cache and data cache.

This service here is part of standard Fiori Launchpad service. But I've seen this issue in my own custom service too.

I've cleared all the Fiori Launchpad services cache too.

 

Any quidance will be really helpful.

 

thanks,

Madan

$filter values are truncated when mapped to FILTER_SELECT_OPTIONS

February 19, 2016, 2:24 pm

Hello gurus!

 

I have the following issue on our development system.

 

We have a GW service that implements an EntitySet. The URL contains a $filter instruction that once SAP catches it, it looks like this:

 

/sap/opu/odata/sap/TEST_SERVICES_SRV/TrimSet?$filter=ChannelId eq '20' and TrimCatId eq 'BASE' and CombinedId eq 'DR3^DTXL2211111111' and GaugeId eq '24' and (ColorId eq 'WWTC' or ColorId eq 'BARE')

 

 

Also very important: both the ABAP data elements and the Entity Properties field lengths matches.

 

ChannelId (max. length = 2)           ==> CHANNEL_ID CHAR 2

CombinedId (max. length = 20)      ==> PROFILE_PSYSTEM CHAR 20

ColorId (max. length = 5)                ==> COLOR_CODE CHAR 5

 

 

Once we jump into the debugger, the IO_TECH_REQUEST_CONTEXT input parameter for TRIMSET_GET_ENTITYSET method has an attribute MR_REQUEST (deep structure) which contains TECHNICAL_REQUEST-FILTER_STRING which value matches the $filter expression in the URL

 

( ( ( ( ( ChannelId eq '20' ) and ( TrimCatId eq 'BASE' ) ) and ( CombinedId eq 'DR3^DTXL2211111111' ) ) and ( GaugeId eq '24' ) ) and ( ( ColorId eq 'WWTC' ) or ( ColorId eq 'BARE' ) ) )

 

 

But the issue is that, if we want to get the $filter values as SELECT-OPTION, the internal table FILTER_SELECT_OPTIONS in the MR_REQUEST deep structure already has the values but truncated:

 

ChannelIdStandard Table[1x4(20)]
TrimCatIdStandard Table[1x4(20)]
CombinedIdStandard Table[1x4(20)]
GaugeIdStandard Table[1x4(20)]
ColorIdStandard Table[2x4(20)]

 

ChannelId gets truncated from '20' to '2'

 

SIGNOPTIONLOW
IEQ2

 

CombinedId gets truncated from 'DR3^DTXL2211111111' to 'DR3^DTXL22'

 

SIGNOPTIONLOW
IEQDR3^DTXL22

 

And both ColorId get truncated as well:

 

SIGNOPTIONLOW
IEQWWT
IEQBAR

 

We have implemented the following note but the issue was not fixed:

 

2245413 - Truncated filter values

Symptom

     The filter value of a property type STRING or XSTRING might be truncated.

Reason and Prerequisites

     Program error in the metadata handling

Solution

     Apply this SAP note to your backend system.

   

     After having applied this SAP note, you have to cleanup the metadata cache on your gateway system via transaction /IWFND/CACHE_CLEANUP      and also your backend system via transaction /IWBEP/CACHE_CLEANUP.

 

https://websmp130.sap-ag.de/sap/support/notes/convert2pdf/0002245413?sap-language=EN

 

 

The curious thing is that if we set the max. length to 0 (zero) in the Entity definition, the values are not truncated anymore. Which it is the workaround i have to do while we get this fixed.

 

Has anyone else experienced this issue??

 

Thanks in advanced!!

Use RFC FMs or direct coding for creating Odata services

February 22, 2016, 1:57 pm

Hi,

 

I am a newbie in Odata. I see that there are 2 ways of creating the odata service. either we can do it using RFC FMs using data mapping ( that exist in ECC) or we can do it using direct coding in Odata itself.

 

Is there any best practice. I read that direct coding is better but then our Gateway and ECC are separate servers so we cannot go directly to any tables and no BAPIs or data elements exist in gateway. Everything is in ECC.

 

 

How should i code?

 

Thanks

How can I create ping notification scenario to multiple domain portals

Hi All,

 

I am trying to create a service for subscription and notification scenario. I followed some of the blogs but my scenario is slightly different from the steps described in these blogs.

 

Pushing Notifications Made Easy!!! : How to Subscribe?

 

Pushing Notifications Made Easy!!! : Push a Notification

 

 

#9 How To... Implement End-to-End Push Notifications with HCPms and SAP Gateway

 

 

I got an understanding from above blogs that its useful more for push scenario where each time a new record is created triggers an event and sends a push notification with newly created record details. But, in my scenario, I have to first ping the client saying that I have a range of records created and provide URI to them to use it to pull from my system. Similarly, I have to notify multiple client systems while maintaining all the newly created items in Queues.

 

My questions are,

 

1. How do we just initiate a ping instead of actual push notification ?

2. How can we maintain queues for multiple clients to read same data one after the other and also ensure that data is not removed from the queue for a specific period of time (may be for 7days)

 

 

Please provide any hints on how to meet this requirement. Any help would be much appreciated.

 

Thank you,

Uday

OData entity association from CDS view : CX_SADL_CONTRACT_VIOLATION

Hello,

 

I created an OData service using SEGW and CDS view thanks to this excellent blog :

Creating Odata services out of CDS views

 

Everything works fine and I really apreciate building OData service with all the sorting and filtering options automatically generated.

 

Although I face a problem when I am using CDS and associations. It doesn't work and I get this error :

 

CX_SADL_CONTRACT_VIOLATION

Entity ' BSA_CARACTERISTICSSET_MATERIALSSet ' was not found

 

I created a MATERIALS entity, with entityset MATERIALSSet and mapped to a CDS view ZV_MATERIALS_ASSO which have an association to CDS view ZV_MAT_CARAC.

I created a CARACTERISTICS entity, with entityset CARACTERISTICSSet and mapped to CDS view ZV_MAT_CARAC.

I created an association in segw from materials to caracteristics.

 

Everything works fine until I mapped the segw association to CDS association like explain in this thread How to build OData Navigation from CDS Associations ?. Then I get this error CX_SADL_CONTRACT_VIOLATION when I request MATERIALSet or CARACTERISTICSSet.

 

I have the feeling that it is a bug from standard SAP, but maybe there is a special way to build these associations using SEGW and CDS ? Why is it looking for BSA_CARACTERISTICSSet_MATERIALSSet ? What is this entityset ?

 

If there is no solution, I am open for another way to build oData service easily because coding all filters and sorting properties are very time consuming...

 

Thank you

User management in Gateway synch'd with user management in ECC

February 24, 2016, 6:58 am

Hello to everyone,

 

we have just started a project that involved the installation of a Gateway (in its own hub). My client has a quite complex landscape that involves ECC, BW, SCM, PI and now the newcomer Gateway. We have understood that the users must have the same name in Gateway as in the ECC (a trusted RFC taking care of the 'mapping'), but we have the problem that the users that enter via Gateway may have to enter directly into ECC, the issue being that our ECC forces a password change every n-days. In that scenario the user (I mean the person) will eventually have to remember one password for ECC and a different password for Gateway. What we would like to achieve is to have the Gateway user password updated in the moment when its homonym ECC user is changed.

 

We've found solutions like Central User Administration but we wanted to know if there is some kind of 'out-of-the-box configuration magic' that accomplishes this directly. If that's a 'no': do you know if Central User Administration is suitable to manage the Gateway users from, say, ECC?

 

Thanks in advance,

Álvaro.

Hi Gurus,

 

I wanted to disable CSRF token for my service ...

 

I have gone through the forum and noted that disable CSRF token at ICF by putting the CSRF parameter as 0.

 

I did the same , but when I test at REST Client during GET ...its NOT responding with CSRF token ... but when I do POST it says that CSRF token inavlid..

 

Looks like disbaling CSRF token works at GET but not at POST I guess..

 

How do I disble CSRF token for my entire service ...?? this service is being called from our web ...

 

Appreciate your help and advise..

Demo Consumption System - how to update data

Hi all,

 

I was able to connect to the former SAP NetWeaver demo system (https://sapes1.sapdevcenter.com/sap/opu/odata/IWFND/RMTSAMPLEFLIGHT/) and read/write data from/to TravelAgencies via OData. I included the csrf token as required and everything worked fine.

 

Now I'm trying to do exactly the same with the new demo system (https://sapes4.sapdevcenter.com/sap/opu/odata/IWFND/RMTSAMPLEFLIGHT/). Reading works fine, but when trying to update a record, I receive an error:  "CSRF token validation failed".

I checked my requests in Fiddler and I'm definitely sending the CSRF token, I received in response to my CSRF-fetch request, with every modifying request.

 

So nothing changed in my OData test environment, but with the new environment I receive an error on modifying requests.

 

I also tried to write to the ProductSet of https://sapes4.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC, but received the same error.

 

Any ideas what I have to change to successfully do update-tests against the new demo system?

 

Thanks and kind regards

Michaela

 

P.S.: The documentation is somehow irritating as it states at the top "The Demo Consumption System is a read-only system.", but for the "GWSAMPLE_BASIC" service it mentions support for "CRUDQ operations for the entity types BusinessPartner, Contact, Product, SalesOrder, SalesOrderLineItem".

So maybe updates are not supported at all in the new demo Environment?

I built an oData service in our backend development system, and I implemented the GET_ENTITYSET method, which just selects the whole table.  I am calling the service through a separate SAP Gateway Server.  I would like to be able to filter this data in the URL call.  When I call the service in the browser, I get the entire table of results, which is to be expected.  When I add the filter parameter, I am still getting all of the results, it isn't applying the filter.  Any ideas as to why this is?  More details below:

 

Entity Set "DriversSet":

Entity Type "Drivers":

Hi,

 

I have created the Fiori app(version 1.28) in web ide and imported into eclipse.

In component.js config, I have mentioned the complete odata service URL without proxy and opening the application in chrome with argument --disable web security.

 

I Just did some Odata model binding to items aggregation of table in my xml view.


And yes, I am using OData V2 model(auto generated code in models.js), handling of csrf token is by default true.

 

I can see the calls are fired one to fetch the CSRF token and the other to GET the data in a batch.

But still, I am facing issue that 403 Forbidden. Not able to understand why this is happening. Please find the attached.
