Finding Enqueue/Dequeue functions
Hi,
Is there an easy way to find the enqueue/dequeue lock functions for a specific table?
I tried to find the enqueue/dequeue functions for table LIKP. It took me a while to find it, but it turns out the name is ENQUEUE_EVVBLKE.
You'd think that the table name would be incorporated into the function name to make it easy to find?!
Does anyone have a suggestion?
Thx.
Andy
Yes bro most of the times the table or field names would be in the Function module name.

Hi,
How to find enqueue and dequeue rate in Oracle Advanced Queue?
Please post if there is any SQL query to find enqueue per second, dequeue per second.
Regards,
GuruHello,
Can you please show me how to run AWR report so that it generates AQ stats you talked about ?The AWR report will be started using the sql script "awrrpt.sql" ($ORACLE_HOME/rdbms/admin/awrrpt.sql).
You will find all details in the original Oracle documentation, keyword AWR.
In the generated report you will find two sections concerning AQ (including a list of all your defined AQs):
==> Persistent Queues
Ordered by Queue Name
indicates queue (re)started between Begin/End snaps
%Exp Msgs - % of msgs enqueued with expiry
%Delay Msgs - % of msgs enqueued with delay
%Trasf Time - % of Enqueue time spent in transformation
%Eval Time - % of Enqueue time spent in rule evaluation
==> Persistent Queues Rate
Ordered by Queue Name
indicates queue (re)started between Begin/End snaps

We are working on a scenario where data is got into SAP through Web methods to create Sales orders.
If we were to use Enqueue / Dequeue function while doing this would the web methods connection hold till the process is complete or would this time out in the middle?
Is there any time out period for the connection with web methods, and if so how can it can be reset to an alternate valueHi,
in ITS if you click on object, you can see the parmaters like
~TRANSACTION
<b>~TIMEOUT</b>
give more time for Time out parameter, that should solve the problem.

2515 Locking FMs to Enqueue/Dequeue/ Which one to use?
I know this question is redundant, and has been responded to a million times....all differently. However, being their are 2,515 function modules to choose from, what are the best choices for locking and unlocking a custom database table?
And, why are their 2,515 of them?
I take that back....many many more!
Thank-You
Edited by: Tom Matys on Sep 23, 2011 12:15 PMHi
I think the best way is to create a new lock object for every custom tables.
Every table should have an own lock object (so own fms to Enqueue/Dequeue) because it makes sure the same lock object is not used for another table at the same time.
If the same lock object is used for many tables it can risk to find a certain record locked although nobody locks it really.

Query on sap locks(ENQUEUE/DEQUEUE)
Hi All,
should the sap locks ENQUEUE/DEQUEUE need to be used for all the updation/insertion of records ino the table?
Please confirm.Should this locking technique be used even for insertion of records into the table?
Regards,
Pra.Hi,
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
- Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
- Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
- Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
Hope this will give a basic idea. -

I hav designed a new application for store i wish to enqueue & dequeue materials which store persons are using.
So how can this be done.Please guide once i open any material in my applcation its locked untill i come out my application.I wishto unclock as my processing is over.
Pls guide whch FM to use.hi,
Create a lock object from SE11 by giving the name
lock object : ezlock_material.
call the function module enqueu_ezlock in th loop to which to all the materials to lock.
to lock the material
call the function module dequeu_ezlock in th unloop to which to all the materials to unlock.
to unlock the material.

Enqueue/Dequeue - Locking/Unlocking object
Hi all,
Please help me working with this enqueue/dequeue command. What I'm trying to do is to lock a Service Order. My requirement is to do a BDC for the Service Order Settlement Rule. So after hitting SAVE, a secondary process will be kicked off to perform my BDC for the same order. Now what Im doubting is that what if user re-enter the same Service Order again so quick. So my BDC program will not be performed immediately since it will be locked by the usser.
So my idea is to lock it first while my BDC program is still running. Any help please? Thanks.Nope. Just 1 BDC -on my 2nd program only. Or to make it simple, I have modified ZXWOCU07 (IWO10009) to perform/kick off a call function( this is being triggered after hitting on SAVE). And this FM contains my checking if SO is now open for change then do the do the BDC.
What I'm thinking is to lock first the SO to block any user from accessing that SO, so it will do the BDC first. But I'm not yet familiar with the locking/unlocking of objects. Please help me on how to use enqueue or locking object. -
Hi all,
i want to lock sales orders with fm ENQUEUE_EVVBAKE and
DEQUEUE_EVVBAKE.
This two fms work fine if i am in the same mode.
I start the fm ENQUEUE_EVVBAKE from one mode and want to unlock the entries from another mode.
The fm DEQUEUE_EVVBAKE runs with no errors. But the lock entry in the SM12 still exists.
Any ideas?

Normally ABAPers will create the Lock objects, because we know when to lock and how to lock and where to lock the Object then after completing our updations we unlock the Objects in the Tables
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
purpose: If multiple user try to access a database object, inconsistency may occer. To avoid that inconsistency and to let multiple user give the accessibility of the database objects the locking mechanism is used.
Steps: first we create a loc object in se11 . Suppose for a table mara. It will create two functional module.:
1. enque_lockobject
1. deque_lockobject
before updating any table first we lock the table by calling enque_lockobject fm and then after updating we release the lock by deque_lockobject.

How to find the existing function module is used in another function module
Hi all,
I created a function module and the same one is called from another function module.
When I tried to find where the first function module is used using Where-used List , I am getting the message "function module not found in selected areas" .
Please guide me what is other method to find whether the function module is used in another one.
Thanks,
Vengal Rao.hi,
Go to UTILITIES-> Update Navigation index.
or go to fucntion group and Generate the Funtion group once.
it will detect all fucntion modules under that function group.

How to find the Obsolete function module in ECC 6.0
Hi Guys,
How we can find the all obsolete function in ECC 6.0, is any T-code to finding the obsolete function modules, or any other way to find.
Could you please help me.
Thanks,
Gourisankar.Hi Gouri,
If you are looking at determining whether a single FM is obsolete or not is by this method:
Go to FM in SE37 -> Goto Attributes Tab -> General Data section -> look above the Edit Lock field ... where SAP places the release status and date of the FM, if the FM is obsolete, the text Function Obsolete appears
This is one way of finding out one FM @ a time
However if you want to check on a mass scale, I dont have a SAP system here hence cant confirm, however, all FMs are stored in TFDIR database table. Please scroll through the fields of the DB table to check whether any field relates to release status or the like. If it does, then from SE16, you can put the value corresponding to "Obsolete" in the field and run to check all FMs.
Cheers,

Before IOS 7, I created an account on my wife and childrens iPhones, iPads and iPod devices with my iCloud account, only having the Find My iPhone function turned on. It worked great. Now, with IOS 7, it is not working and I don't have the option to have the Find My iPhone function on my iCloud account on their devices. Does anyone know how to make this work? My family loses their devices frequently and I am concerned I won'e be able to help them find them. Thanks!!
They only need their main iCloud account to have Find My iPhone on. If your account is not their main account it won't work. Only one account can enable that function on a device. They don't need to have the app on their devices unless you want them to find you.
If you can see the devices when you log into their accounts on your Find My iPhone app they are being recognized by the app. But as Winston said if they're not turned on, if they are not on a network, cell or wifi, then they will read as offline. This often happens when I look for my wife's phone when she is at work, her wifi system there does not keep the connection active when the device goes to sleep and in some areas of the building there is poor to no cell connection. And sometimes the service just doesn't pick them up for no obvious reason.
iOS 7 has several annoying glitches right now that hopefully will be resolved soon and this could be one for you. I would try this again by having all the devices in one location , restart all of them, make certain the function is enabled on all of them and that wifi is connected ( if you have a wifi network available ) or that they are connected to a cell network with a strong signal. Then launch the app on your phone and log in with their accounts, their locations should show up. -
i am trying to synch my ipad to my computer and i have turn off my Find my iPad function. I have put in my Apple password to do that. i know my password is correct but it says it is not correct. How do I fix that?
And I am incorrect...
Have you ever changed your passcode?
Try again. Maybe a typo? -
