When to syncronize automation queue (calling cl_gui_cfw= flush)
Hello,
I'm using OO ALV (using cl_gui_alv_grid class), with checkboxes and user interaction, and it all seems to work OK. But i'm not calling class method cl_gui_cfw=>flush in any point at my program, because I don't clearly understand what's the method's use and need.
Could you please explain this to me? I've already read some SAP help about control framework, automation queue and all but still don't get it (so please try to explain instead of simply pasting SAP help links).
Many thanks
Ok, from your last post i deduce that for every control class (i.e. cl_gui_alv_grid), there's a proxy class in the application server. All that is transparent to the programmer.
But could you give some example of when the necessity arises to use the flush method explicitly?
My ALV code in this case isn't much complicated, i just call the check_changed_data method to detect changes in checkboxes and then call refresh_table_display. But would like to understand this fully so I can be prepared for any case.
EDIT: I guess the need depends on the context of the program being developed. But I understood the concept so I'm closing the thread.

What is the functionality CALL METHOD CL_GUI_CFW= FLUSH
Hi,
What is the functionality of method "FLUSH" in class CL_GUI_CFW
Should it be used after every call method CL_GUI_FRONTEND_SERVICES=>......
What is the purpose of using it? What happens if we don't use it?hi
good
The class CL_GUI_CFW contains static methods that apply to all instantiated custom controls when you call them.
You can force a synchronization point in your program by calling a method that is not buffered, or by calling the static method FLUSH.

SUBMIT inside a method & the automation queue
Hi,
I call a method via a tree toolbar button in that calls a standard SAP report using the SUBMIT AND RETURN command. This is done within a screen with several docking containers and split screens attached.
The problem is that when I press the toolbar button, the report (which also has docking container) is presented partially inside my screen.
When I put a BREAK-POINT on the SUBMIT statement it is good and I can see SAP's report with no issues and I do not see my screen. When I take the break point off it is back to the original problem.
This leaves me to think that it is an automation queue problem or something like that.
How can I get over this?
Thanks,
ItayHello Itay
I tried to simulate your situation. Perhaps you get from this sample report (which was copied from BCALV_TREE_DEMO and the adjusted) some ideas how to solve your problem. In my report all controls are displayed properly.

Hi,
May I know, What is the functionality of the following 2 sentenses,
1-cl_gui_cfw=>flush
2-cl_gui_cfw=>false?
ThanQ.Hi,
In OO approach, calling a Control-method does not imply that the method is automatically executed at runtime. Initially, the system buffers methods in a queue, referred to as the Automation Queue, when they are called in the ABAP program. The execution sequence of the methods therefore remains unchanged. However, the methods are only executed if they are transferred to the frontend via Remote Function Call (RFC) using method FLUSH. This means that the Automation Queue is used to reduce the number of RFC calls required.
(Due to the buffering of control methods in the Automation Queue, the method calls and the remaining ABAP code are executed at different times. Method FLUSH thus determines a synchronization point).
While communicating between the Automation Controller and the ABAP Objects Control Framework the automation queue uses GUI RFC calls. To minimize the network load between the backend and frontend, calls from the backend to the frontend are buffered and sent to the frontend in a single batch at defined synchronization points. A synchronization point occurs when you use a method call that is not buffered or explicitly call the generic synchronization method ( CALL METHOD cl_gui_cfw=>flush ).
cl_gui_cfw=>false is method which used to hide the border around the Splitter Container.
CALL METHOD go_splitter_container->set_border
EXPORTING
border = cl_gui_cfw=>false.

Why do we use cl_gui_cfw= flush method in Object Oriented ALV programming
Dear Friends,
Please solve my query regarding control framework. Why do we use cl_gui_cfw=>flush method in Object Oriented ALV programming. I studied and found that this method transfers automation queue to Front end. But I could not find any further update on this.
Thanks & Regards
Amit SharmaGenerally this is to restrict the traffic b/w frontend and backend. This means that every operation in Control Framework should be first buffered in the backend and synchronized with the frontend at certain points (one of this point is calling synchronization method cl_gui_cfw=>flush ). This explicit order of synchronization is due to RFC call needed for every communication b/w front/back end. So to avoid to many RFC calls we do it only at certain time.
Please refer [Automation Queue|http://help.sap.com/saphelp_wp/helpdata/en/9b/d080ba9fc111d2bd68080009b4534c/frameset.htm]. I think it explains the concept quite well.

Hi all,
what is the use of the class cl_gui_cfw=>flush. in alv object?
Thanks
ANUPAMHi,
Use this method to synchronize the automation queue. The buffered operations are sent to the frontend using GUI RFC. At the frontend, the automation queue is processed in the sequence in which you filled it.
If an error occurs, an exception is triggered. You must catch and handle this error. Since it is not possible to identify the cause of the error from the exception itself, there are tools available in the Debugger and the SAPgui to enable you to do so.
Debugger: Select the option Automation Controller: Always process requests synchronously. The system then automatically calls the method cl_gui_cfw=>flush after each method called by the Automation Controller.
SAPGUI: In the SAPgui settings, under Trace, select Automation. The communication between the application server and the Automation Controller is then logged in a trace file that you can analyze at a later date.
CALL METHOD cl_gui_cfw=>flush
EXCEPTIONS CNTL_SYSTEM_ERROR = 1
CNTL_ERROR = 2.

CL_GUI_CFW= FLUSH giving short dump
hi,
i have got two servers. one for development and other for quality. in development my CL_GUI_CFW=>FLUSH is working fine, but when i try to execute my prog in quality "flush method" is giving short dump, its returning sy-subrc <> 0.
can anybody suggest possible causes of the same.
The server status are all the same for quality as well as development.
thanks
pratyushHello Pratyush
You may want to have a look at my sample report ZUS_SDN_TWO_ALV_GRIDS_3 in thread
[how to refresh the contents of a grid?|how to refresh the contents of a grid?;.
Most control events do not trigger PAI of the dynpro. Thus, they behave similar like calling a search help or F1 help.
The automatic flushing which occurs at PBO is done the following way:
METHOD handle_user_command.
* define local data
DATA:
ls_row TYPE lvc_s_row,
ls_knb1 TYPE knb1.
CHECK ( sender = go_grid1 ).
CHECK ( e_ucomm = 'SAVE' ).
CALL METHOD go_grid1->get_current_cell
IMPORTING
es_row_id = ls_row.
READ TABLE gt_knb1 INTO ls_knb1 INDEX ls_row-index.
CHECK ( ls_knb1-kunnr IS NOT INITIAL ).
PERFORM entry_show_details.
* Triggers PAI of the dynpro with the specified ok-code
" CALL METHOD cl_gui_cfw=>set_new_ok_code( 'DETAIL' ). " not on 4.6c
CALL METHOD cl_gui_cfw=>set_new_ok_code
EXPORTING
ok_code = 'DETAIL'.
ENDMETHOD. "handle_user_command

Isdn Layer 1 deactivated when there is no active call
Hi All,
I am in Nairobi Kenya. Here we use ISDN Basic-net3 and my problem is that most of the telco switches here deactivate Layer 1 when there is no active call.
When I try to initiate a call by using the ISDN test call command I get an error to the effect that B channel is not available.
The only way I can initiate a call is I first call the line then and then disconnect. Then I have about 5 seconds to make a test call and pings are successful. How do I make the router initiate a call when layer 1 is deactivated.
the debug isdn q921 out has nothing till a call comes in.
I also understatnd that European ISDN switches deactivate Layer 1 when there no active call. I dont have a problem with one of the switches, coz it does not bring down the line when there is no active call.
Thakx in advance
MartinThanks for the quick response.
It is a cisco 1760
The IOS is c1700-sv3y-mz.122-15.T5.bin
When I try to make a test call the show isdn status initially indicates that the router is trying to activate layer 1 then after 5 seconds it indicates that it is deactivated.

Checking number of queue calls and redirecting
I am wanting to add a variable into my script that checks the number of calls that are currently queued and if the number of queued calls is greater then three any additional calls will be sent down a Call Subflow to another script. I have attached a copy of the script I am using, the issue that I am facing is that when I get a call queued in my Reception CSQ the next call goes down the call subflow when in actually I want the second and third call to queue and the fourth call to go down the call subflow.
Looking at your script you are checking if there are agents logged in, and if so you send the call to Queue Call label, which is below the check for calls in queue, your success node from agents logged in should go to another label that checks calls in queue.
HTH,

We can not clear all recents(30 recents call). When Tango show "No recents call". We touch other buttons and come back to Recents button again. It still show 30 recents call.

When i came home i called apple to check whether my phone is locked or not and they said that its locked to US Verizon even though when i checked on iphoneimei it said sim status unknown. I put my 2degrees (NZ carrier) in today and it worked fine. I got into the settings and turned off the automatically part of carrier and there were 3 options for me to choose 2degrees vodafone and telecom. Because of that, im quite confused abt whether my phone is locked or not since im from vietnam so i want to know if i can use vietnamese sim card when i go home. Thanks for your help@verizon
Hi tranvietanh - I appreciate you contacting us all the way from New Zealand! I can confirm that the iPhone 5s and all of our other 4G LTE device are not SIM locked. As the carrier in New Zealand may not support the exact same frequencies and cellular bands that we use on our network, we are unable to support the device if using a 3rd party SIM.
Thank you,

i got a macbook pro 13 inch core i5 late 2011 , it came with osx lion and i been using facebook videocalls normaly , now i updated to Mountain lion
but when i use facebook video calls in (safari ,chrome ) i see the window box but i only see my self i can hear my friends but cant see em, they also can see me and hear me but i just see me and hear them .
any ideas ?Your wifi problem sounds very much like the problem I had. The wifi would drop out, the icon showed it was still connected. If I turned it off, I couldn't turn it back on. Another user here pointed me to the problem, which was the wifi cable (the flat cable goint from the card to the motherboard). I found it on ebay for $13 and it's been running fine since I replaced it. This is the repair guide for your machine. The part number will be on there if you click the link.

I have two different 5s's with two different phone numbers but they are both using the same iCloud/apple account. After upgrading to iOS8 when I get a phone call on one phone both phones ring. One phone is for work and one is for private and I don't need both phones to ring from one call. It's bizarre.......is this supposed to be like this? If so where can I turn it off?? And while we are at it iOS8 has installed iBooks on both of my phones and iTunes won't let me uninstall it. I don't need or want iBooks on my phones.
Hi,
There are two easy fixes to this.
One, you can set up Family Sharing, in which you can have two different iCloud Accounts, yet still share the same apps, music, media etc.
Two, go to Settings and turn-off "Handoff". This can be found under the General page.
Hope this helps! -
How do I change my phone settings on my iPhone 5 so that when I make a phone call while I am on the phone call my phone stays lit up. It never goes black so I am constantly hitting other buttons while I try to talk like mute or FaceTime or speaker! Please help this is so annoying! It's like all I need to do is fix the settings somehow and I have gone through all of my settings and I can't find where to do this!
Is the phone in a case? Try taking it out of the case. If that doesn't work, then your proximity sensor is broken. You'll need to bring your phone to Apple for evaluation.
