Webpage cannot be found

[Former Member]

I have developed a service using transaction SEGW and set an external breakpoint at the very top of the GETENTITYSET method. of the Data Provider Class Extension.

When I enter these urls (although I don't expect them to do anything), the breakpoint is reached.

http://xxx.yyy.net:8080/sap/opu/odata/sap/Z_IB_QBSUMM_SRV/ZSCMQBSUMMARTBLCollection? 

http://xxx.yyy.net:8080/sap/opu/odata/sap/Z_IB_QBSUMM_SRV/ZSCMQBSUMMARTBLCollection?$top=5

http://xxx.yyy.net:8080/sap/opu/odata/sap/Z_IB_QBSUMM_SRV/ZSCMQBSUMMARTBLCollection?$filter=

However when I enter the url

http://xxx.yyy.net:8080/sap/opu/odata/sap/Z_IB_QBSUMM_SRV/ZSCMQBSUMMARTBLCollection?$filter=fromdate eq 'xxx'

I receive a HTTP 400 Webpage Cannot Be Found error.

So apparently once I put something after the $filter= on the URL, is when I get the Webpage Not Found error.

I followed the example provided in this YouTube video by Jeff Gebo (which I found extremely helpful)

except using the BANK table, I used a custom Z table.

I don't quite understand why when I put something after $filter= in the URL, the webpage becomes "not found".

Never mind everybody.  I found the error in the error log.  I didn't have fromdate marked as a filter.
