The
data packages sent to SAP GUI are smaller, since
- no technical field names are sent with the screen
- only the top-level menu items are initially sent
How
to measure the data package sizes: Open 2 connections to the
same system in saplogon, one of them with low speed connection
on. Activate GuiXT system trace. Perform the same transactions
in both windows. The length of each record is show in a line
api_pbo1 (Beg) (int) leng=xxxx
for each screen.
Some
typical figures:
VA01,
2nd screen:
23,841 high speed connection
20,347 low speed connection
FB01,
1st screen
7567 high speed connection
2274 low speed connection
FB01,
2nd screen
1316 high speed connection
892 low speed connection
Typically,
for the first screen of a transaction the difference is larger
(menu items not sent). But please observe: when the user clicks
on an item, there is an additional application server request
needed in low speed connection mode. For screens with a table
control (like the above VA01 example), the size depends very
much on the window size (i.e. on the number of table lines that
fit into the window).
The
history function of SAP GUI is not possible with low speed
connection. |
