What is control tables in abap hr?what is the purpose?
what is control tables in abap hr?what is the purpose?
These are the screen elements used to display tabular data they can be called
as screen tables( like STEP LOOP).To use table control we have to create it on the screen using SCREEN PAINTER(SE51) and declare a control variable of TYPE TABLEVIEW using CONTROLS statement in the ABAP program. We have to use LOOP .. ENDLOOP statement in both PBO and PAI with or without AT int_table parameter. IF AT int_table parameter is not used than we have to place a MODULE call between the LOOP...ENDLOOP statement to fill the screen table rows from the ABAP program in PBO and program our own scrolling functions
using OK_CODE field.
Having a parallel loop(at screen table rows & int table rows) by using parameter
AT int_table makes the ABAP code simple.
A special structure of type CXTAB_CONTROL is used to set/get various
attributes of table control at runtime like CURRENT_LINE ,TOP_LINE.
ABAP declaration
CONTROLS: tab_con TYPE TABLEVIEW USING SCREEN nnnn
Here tab_con is the same name we used in screen for the table control.
This ABAP statement will declare a control variable that will be used to access
the table control , and set it's various attributes like number of fixed columns(tab_con-FIXED_COLS) ,total number of records it will display(tab_con-LINES).It is of type CXTAB_CONTROL and is a deep structure(structure containing structures).
REFRESH CONTROL tab_con FROM SCREEN nnnn
This ABAP statement will initialize the table control on the screen nnnn to its initial values.
PBO processingI
n PBO we have to use the screen LOOP ...ENDLOOP statement , with or without
intenal table.
LOOP WITH CONTROL tab_con.
MODULE fill_tab_con.
ENDLOOP.
Here a module should be called between the loop endloop statement to transfer
data from th ABAP program to the screen table through a structure.This module
should use the CURRENT_LINE attribute of the table control variable to get the
current screen table record index to read the data from the internal table into a work area.
e.g.
READ TABLE int_table INDEX tab_con-CURRENT_LINE
The record read will be placed in the header line of the internal table and will be available to the similarly named screen fields or if these are different it can be written explicitly. e.g.
screen_field_name = int_table-field_name
LOOP AT int_table INTO workarea WITH CONTROL tab_con CURSOR i FROM
n1 TO n2.
ENDLOOP.
Here the module call is not required to fill the screen table.The CURSOR parameter is a integer of type I indicating which absolute internal table line
should be the first to display on the table control .FROM n1 TO n2 can be used
to restrict the starting line and ending line number of the internal table , they are of type SY-TABIX.
In both cases before the LOOP statement a module should be called which
is generally for setting of status ,in which we should fill the LINES attribute
(tab_con-LINES ) of the control with the total number of internal table records,doing this ensures correct and automatic scrolling.
The ABAP statement DESCRIBE TABLE int_table LINES lines can be used
to get the total lines in an int table.
PAI Processing
We have to use LOOP ... ENDLOOP in PAI so that data can transfer fro table control to ABAP program. If we want to write changes to the data we should
call a module between the LOOP ... ENDLOOP. The MODULE call to process user commands (SY-UCOM) should be called after the ENDLOOP statement.
e.g.
PROCESS AFTER INPUT
MODULE mod AT EXIT-COMMAND.
LOOP AT itab_table or LOOP "depending on whether we are using AT int_table
MODULE modify_int_table.
ENDLOOP.
MODULE user_command.
In the MODULE call modify_int_table we can use
MODIFY int_table FROM workarea INDEX tab_con-CURRENT_LINE
or we can use
int_table-field_name = screen_field_name.

What are Controlling component, Controlling area component code?
Hello Experts,
Can you help me understand the following terms as used in the following 4 quotes from the SAP site:
What is controlling component, controlling area and component code and how are they related? I will appreciate explanations with real life examples.
Can you also help explain each of the 4 quotes with examples. Thanks.
Quotes:
1. You can define a maximum of 16 posting periods for each fiscal year in the Controlling component (CO)
2. You need to specify the fiscal year variant for each company code.
3. When you create a controlling area, you also need to specify the fiscal year variant
4. The fiscal year variants of the company code and controlling area may only differ in the number of special periods used. You need to ensure that the fiscal year variants match, in other words, they may not have a time conflict.Hi
1) firstly, let me tell you one thing that
Controlling is referred as Component.
like Order Management as one component.
Profitability Analysis is as component.
Activity-Based as component.
2)similar to company code in FI "Controlling area" in controlling.
Company code has legal entity:generally organization is company code.
Controlling area doesn't have legal entity.
because the will define for internal purpose.
to know the costs of the organization.
3)To Build relation between FI and Controlling we assign the Controlling area to Company code.
FI--- IS FOR EXTERNAL REPORTING PURPOSE.
CO-- IS FOR INTERNAL PURPOSE.
4)Fiscal year variant and Posting periods are defined at FI Level.Those only we use in Contolling Area. -
What version control system you use?
We are 20 developer and we use bitkeeper as a version control system.
But we have 4 envirronnement.
dev/test/pre-prod/prod.
Sometimes, 2-3 projects are affecting the same packages.
And different packages version is all over the place since we have 4 envirronnements.
What version control system you use for packages?
Would be cool to have a version control system intergrated to our tools, like toad, pl/sql dev or sql developer, is there one for those tools?
Is the tool you using it doing all you want it to do?
Have any link for me to check out?Hi,

What is CONTROL - M process ?
Hi to the group,
can some one let me know - what is CONTROL - M process in detail.
Is it related to back ground job scheduling ?
Regards
MadhuriCONTROL - M is a non-SAP-tool to control the job scheduling in SAP. It is really advanced as you can do all related file handling and/or archiving, control jobs and processes between vaious systems including error handling, conditional processing and so on.
Usually only big companies with many systems will use it; the administration of CONTROL-M can be a fulltime-job for more than one administrator.

What is control form function module.
hi
what is control form function module.Hi Chaitanya,
The function module CONTROL_FORM can be used to pass the control
commands to FORM THROUGH ABAP/4 PROGRAM.
<b>Function Call</b>
CALL FUNCTION 'CONTROL_FORM'
EXPORTING COMMAND = ?...
EXCEPTIONS UNOPENED =
UNSTARTED =
<b>Export parameters:</b>
COMMAND
Enter the SAPscript statement you want to execute in ITF format, but without the statement paragraph attribute '/:'.
<b>Exceptions:</b>
UNOPENED
The current form function could not be executed, since the form output was no yet initialized using OPEN_FORM.
UNSTARTED
No form was opened yet.
Possible reasons:
>The form processing was started using OPEN_FORM without specifying a form name, but no form was opened yet using START_FORM.
>The last used form was closed using END_FORM, but no new form was opened using START_FORM.
>The last filled page of the current form has no subsequent page. In this case, the system automatically terminates form printing after this page. You need no explicit END_FORM call.
>In the current form, no page contains a main window, but a text element shall be output in the main window.

DATA General data field
INFO General info field
Please help me in this regad
Thanks in Advancehi,
here are some information about control tables :
The control table is the one which specifies how your data changes in the table and how you want your table to be maintained.:
The following are the delivery classes:
A: Application table.
C: Customizing table, maintenance by customer only.
L: Table for storing temporary data.
G: Customizing table, entries protected against overwriting.
E: Control table.
S: System table, maintenance only by SAP.
W: System table, contents can be transported via own TR objects.
The Control Tables specify that it is the table where data is not changed frequently and pertains to information for the flow of the system.

QoS and1000v packet and control traffic
It is important to reserve bandwidth for 1000v packet and control. However, I know of now way to mark those packets so that they can be given end to end QoS treatment.
The 1000v allows me to match traffic on output queuing using the following.
match protocol n1k_control
match protocol n1k_packet
With that, in conjunction with a policy-map type queuing, I can reserve bandwidth for1000v packet and control traffic leaving the VEM towards the upstream switch. However, once it gets to the upstream switch, the lack of an appropiate CoS value prevents me from properly queuing the traffic as it heads towards the VSM.
I have the following configuration.
A pair of N7Ks.
1000v VSM running on a pair of 1010 Appliance connected to the N7Ks
A pair of UCS 6248UP connected to the N7Ks
B200 M2 Blade Server with M81KR converged Network Adapter in a 5108 Chassis running ESXi with the VEM installed.
2208XP I/O Modules connecting the 5108 to the 6248UP
vCenter running on a separate ESXi host outside the UCS connected to the N7Ks
Once the 1000v packet and control traffic leaves the VEM, it is unmarked. As a result it hits the 2208 and lands in the best effort queue all the way through the 6248 and into the N7K.
Everything I've read suggests 1000v packet and control traffic should be marked with a CoS value of 6 but how do I do that for packets leaving the 1000v?
Thanks in advance for your help.
Jim MarinelliHi Jim,
As you pointed out, the VEM would mark the control/packet traffic with CoS 6. You can set the UCS vNIC policy to accept this tag by setting the 'Host Control' parameter to 'Full':
http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/gui/config/guide/2.1/b_UCSM_GUI_Configuration_Guide_2_1_chapter_010100.html
So this tag would persist till it leaves the UCS Fabric Interconnects.
Thanks,

Hi Gurus,
Please explain me that what is Control file and what was the purpose of it in SAP Oracle DataBase.
Thanks.Hi Kalyan
<b>What Is a Control File?</b>
Every Oracle Database has a control file, which is a small binary file that records the physical structure of the database. The control file includes:
The database name
Names and locations of associated datafiles and redo log files
The timestamp of the database creation
The current log sequence number
Checkpoint information
The control file must be available for writing by the Oracle Database server whenever the database is open. Without the control file, the database cannot be mounted and recovery is difficult.
The control file of an Oracle Database is created at the same time as the database. By default, at least one copy of the control file is created during database creation. On some operating systems the default is to create multiple copies. You should create two or more copies of the control file during database creation. You can also create control files later, if you lose control files or want to change particular settings in the control files.
<b>Guidelines for Control Files</b>
This describes guidelines you can use to manage the control files for a database, and contains the following topics:
Provide Filenames for the Control Files
Multiplex Control Files on Different Disks
Back Up Control Files
Manage the Size of Control Files
Role of Control File will remain the same even when you use Oracle with SAP. Just there will be some more entries in the file.
Refer the link below as well:
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006143
Hope this should clear you doubt.

<P>
Details on these tools are found in the Administration
Guide that accompanies the product.Hi Vsu,
To know the query execution time:
First execute the query in RSRT. To Check how much time it is taking to execute.....Goto SE11> Give table name RSDDSTAT_DM or RSDDSTAT_OLAP in BI7.0 or RSDDSTAT in BW3.x.> Display -> Contents-> Give from date and to date values as today, user name as Ur user name, and give the query name --> execute.
Now u'll get a list with fields like Object name(Report name), Time read, Infoprovider name(Multiprovider), Partprovider name (Cube), Aggregate name... etc. Here the time read represents the time it has taken to execute the query.
If the data to that query is comin from many cubes in that case copy the step id from the above result and go back give the step id and Object name (Query name), User iD, Date now execute... It will display the total time the query executed in the time read field.
Hope ity helps you...

What is Control Accounts? What is C/A for A/R and A/P?
I have US COA set up automatically by SBO. So all accounts are already set up there.
When I go to: Administration > Setup > Financial > G/L Account Determination:
In Sales (general) tab, I noticed Account Receivable with (...) next to it.
When I clicked it, it will bring window of Control Accounts for A/R.
In Purchasing (general) tab, I noticed Account Payable with (...) next to it.
When I clicked it, it will bring window of Control Accounts for A/P.
1. What is this Control Accounts?
Can I leave it blank as it is? If I left it blank, will it affect financial result? If the answer is it is OK to leave it blank then no need to answer my questions below. If I need to fill it out, then I need help with questions # 2 and # 3 below.
2. Inside this Control Accounts for A/R: (note: we do business Domestic only)
What will be the correct Account Code for Down Payment Receivable? (My guess it is A/R Domestic)?
What will be the correct Account Code for Open Debts? (My guess it is A/R Domestic)?
3. Inside this Control Accounts for A/P: (note: we do business Domestic only)
What will be the correct Account Code for Down Payment Payable? (My guess it is A/P Domestic)?
What will be the correct Account Code for Open Debts? (My guess it is A/P Domestic)?
What will be the correct Account Code for Assets Account? (My guess it is A/P Domestic)?
Thank you.Hi Tom
You can define a G/L account as a control account.
A control account links the business partner accounts to the general ledger. You must enter a control account in every business partner master record. Whenever you post a document to a business partner account, the system automatically adds a journal entry to the general ledger, which posts the receivables or payables to this control account.
Some transactions, such as transactions with bills of exchange, must be posted to special control accounts. Therefore, you can assign these special accounts to predefined transaction types, such as
Open Debts, Assets Account, Down Payments Receivable/Payable or other (country-dependent).
You can also enter default control accounts under Administration  Setup  Financials  G/L Account Determination. These accounts appear by default whenever you create a new business partner.
The system displays the total account balance in the business partner master record. From there you can navigate to the line item display of the account. In the line item display, the system displays the debit values in black and the credit values in green and in parentheses.
If you are working with several control accounts, the system can display the business partner balances separately for every control account. To activate this, choose Administration  System Initialization  General Settings and select the Display Accounts Balance by Control Accounts indicator on the BP tab.
You must have the proper authorization to view the accounts and balances.
Hope this helps.

What are control tables?
hi
I'm fresher in ABAPn have recently come across the concept of control tables could somebody pls tell me what exactly is a control table?Hi Sana,
welcome to SDN.
*<b>Control Tables</b>
The search indexes for address data, as well as the address data itself, are client-dependent. There can now be other differentiations within a client. These are called "Index pools".
The division reflects the fact that multiple areas of master data are involved, which differ from the business embedding in the SAP System and from the technical implementation.
Two such index pools are currently defined in table TSADRVGRP with a technical key derived from control table TSADRV:
