Outbound sync ABAP performance

[Dimitri]

Hi,

We have a scenario ABAP proxy <-> SAP PO <-> web service receiver. The scenario is synchronous.
When we check, on the back end system, transaction SXMB_MONI, we see a time difference

Checking the yellow part, we see a big time difference

• begin = 20201116 113830.202277
• end = 20201116 114302.085452

That means a delay of 4 and a half minutes. What does it mean?

All insights would be great!

Thanks a lot.
Dimitri

Hello Dimitri,

Since this is a synchronous scenario, an HTTP_SEND step in a sender system will accumulate all time that it spent sending a request message and receiving a response message (assuming it doesn't timeout before response arrives back) - the end time of an HTTP_SEND step of the request message can also get correlated with performance trace data of the response message that the sender system received and that you will see in SXI_MONITOR (an HTTP_SEND step end time of the response message shall match an HTTP_SEND step end time of the request message). In other words, this will include the entire turnaround of the message - including network time between a sender system and SAP PO, processing time in SAP PO, network time between SAP PO and a receiver web service, and processing time undertaken by the receiver web service. With so many components involved and contributing to this figure, I don't think it will be possible to identify a performance killer from what you see in the sender system alone. Can you have a look into message log for this message in SAP PO and derive from there, how much time SAP PO spent for request and response processing, and waiting for response from the receiver web server to which it sent the request? From there, we shall be able to see where major time was spent - for example, was it processing in SAP PO, or communication and processing on the web service side.

Regards,

Vadim

Hi Dimitri ,

did you activated the Time Zone function in the SAP System for day/light changes ?

Thanks , Sankar

Hi,

This is a delay. No winter/summer time difference.
I want to understand what I'm looking at here.

Kind regards,
Dimitri
