400 Bad HTTP request: path too long

[Former Member]

Dear Community,

I got the following error, while sending a http request with more than 4096 Bytes via ODATA to the Netweaver AS.

Technical information:

Netweaver without J2EE service

Not the same case, but may trigger some solution:

This problem occurs if you are using HTTP GET request instead of HTTP POST request. For the HTTP  GET request, there's a length restriction of around 2000 characters.
So, it should work fine if you're switching the HTTP request method from the outdated GET to the recommend POST method. For the POST request there's no limitation in overall length/size.

Please go to iView portal_content/com.sap.pct/platform_add_ons/com.sap.ip.bi.bex3x and change property "HTTP Request Method" to "HTTP: POST". Then try again.

You can also find it using the following path:

Content Administration -> Portal Content -> Content provided by SAP ->Platfrom Add-Ons -> Business Intelligence -> iViews -> BEx web (the second one with 3x at
the end of the iView ID)
