Lokeswar,

Problem might be with the XML body. Why don' you post the request body.

Thanks

Hi Krishna ,

<atom:entry xmlns:atom="http://www.w3.org/2005/Atom">

<atom:id/>

<atom:title>Gateway subscription</atom:title>

<atom:author/>

<atom:updated/>

<atom:content type="application/xml">

Hi Krishna ,

Actually my Service is a sdata service and before posting i need to get X-CSRF-TOKEN ,  but while getting i'm not able to X-CSRF-TOKEN ..,

Pl suggest , is it needed to fetch and pass X-CSRF-TOKEN..,

Regards,

Lokeswar.

The XML body looks good. So I doubt the problem has to be with SAP's XML parser.

Why are you using sdata. I would suggest activating oData node and using oData version of the service.

[Former Member]

Hi Krishna,

Thanks for ur suggestion,

Under oData i found wfservice node under IWWRK .

Url which i tried to post  :

<GW port >/sap/opu/odata/iwwrk/wfservice/SubscriptionCollection?$format=xml

While executing system is raising error message as forbidden-403 ..,

pl suggest ..,

[Former Member]

Hi Krishna ,

That is the problem with URl,

But now i'm facing the below error :

<?xml version="1.0" encoding="utf-8"?><error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><code>005056A509B11EE1B9A8FBE8A100F78B</code><message xml:lang="en">The Data Services Request contains SystemQueryOptions that are not allowed for this Request Type</message></error>

[kammaje_cis]

Is it a post? Did you provide CSRF token? More info would make it easier to help.

Also here is a document using oData.

HI Krishna ,

I have provided the X crsf token,but im facing the same error as below :

400 Bad Request

<?xml version="1.0" encoding="utf-8"?><error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"><code>/IWFND/COD/011</code><message xml:lang="en">The SAP system could not process your request. Contact your administrator</message></error>

[kammaje_cis]

FND and BEP error logs can help and cab provide more info.

With SLG1 transaction i found that the error is :

Subscription rejected by backend:

Long text exists

Pl let suggest that what is root cause of the error

[kammaje_cis]

Run transaction/IWBEP/VIEW_LOG and check the error.

[Former Member]

While executing /IWBEP/VIEW_LOG , no logs were registered here..,

[Former Member]

Any authorizations required for subscription , from the below link i found that /IWBEP/RT_SUB_USR is required ..,

Subscription Management - SAP NetWeaver Gateway Foundation (SAP_GWFND) - SAP Library
