SET PARAMETER AND GET PARAMETER

What is the difference between Set parameter and Get parameter?

Hi,
Set parameter is used to put some value into ABAP memory area, get paramter is used to retrive values form ABAP memory.
refer the below sample code.
here i am taking one material number and i am passing that mateial number by using 'set parameter id', the material number will be stored in ABAP-memory area 'MAT', and then i am calling the Tcode 'MM03', after executing the Tcode (from program) automatically 'MM03' will reads that material number from that ABAP-memory area and it will displays the 'MM03' tcode along with material number.
you can find the parameter-id's from data element of that field.
parameters: p_matnr like mara-matnr.
set parameter id 'MAT' field p_matnr.
call transaction 'MM03'.
Reward if useful.
Thanks,
Sreeram.

Set and get parameter

what is set parameter and get parameter ? give me one example.

Hi Pradeep,
SET PARAMETER and GET PARAMETER, is mainly used when you are dealing with SAP MEMORY.
Meaning - You have multiple sessions open. Now you want to access from variables declared locally in different sessions.
You can use
SET PARAMETER
to assign the value to SAP Memory and using
GET PARAMETER
you can retreive the values assigned by previous statement in a different session.
Reward points for helpful answers.

How to use SET and GET parameter commands ?

Explain these two giving an example?As which is used for what?

Hi Albert,
 SAP allows you to make use of SPA/GPA technique to fill the input fields of a called transaction with data from the calling program.SPA/GPA parameters are values that the system stores in the global, user-specific SAP memory. SAP memory allows you to pass values between programs. A user can access the values stored in the SAP memory during one terminal session for all parallel sessions. Each SPA/GPA parameter is identified by a 20-character code. You can maintain them in the Repository Browser in the ABAP Workbench. The values in SPA/GPA parameters are user-specific.
ABAP programs can access the parameters using the SET PARAMETER and GET PARAMETER statements.
To fill one, use:
SET PARAMETER ID <pid> FIELD <f>.
This statement saves the contents of field <f> under the ID <pid> in the SAP memory. The code <pid> can be up to 20 characters long. If there was already a value stored under <pid>, this statement overwrites it. If the ID <pid> does not exist, double-click <pid> in the ABAP Editor to create a new parameter object.
To read an SPA/GPA parameter, use:
GET PARAMETER ID <pid> FIELD <f>.
This statement fills the value stored under the ID <pid> into the variable <f>. If the system does not find a value for <pid> in the SAP memory, it sets SY-SUBRC to 4, otherwise to 0.
To fill the initial screen of a program using SPA/GPA parameters, you normally only need the SET PARAMETER statement.
The relevant fields must each be linked to an SPA/GPA parameter.
On a selection screen, you link fields to parameters using the MEMORY ID addition in the PARAMETERS or SELECT-OPTIONS statement. If you specify an SPA/GPA parameter ID when you declare a parameter or selection option, the corresponding input field is linked to that input field.
On a screen, you link fields to parameters in the Screen Painter. When you define the field attributes of an input field, you can enter the name of an SPA/GPA parameter in the Parameter ID field in the screen attributes. The SET parameter and GET parameter checkboxes allow you to specify whether the field should be filled from the corresponding SPA/GPA parameter in the PBO event, and whether the SPA/GPA parameter should be filled with the value from the screen in the PAI event.
When an input field is linked to an SPA/GPA parameter, it is initialized with the current value of the parameter each time the screen is displayed. This is the reason why fields on screens in the R/3 System often already contain values when you call them more than once.
When you call programs, you can use SPA/GPA parameters with no additional programming overhead if, for example, you need to fill obligatory fields on the initial screen of the called program. The system simply transfers the values from the parameters into the input fields of the called program.
However, you can control the contents of the parameters from your program by using the SET PARAMETER statement before the actual program call. This technique is particularly useful if you want to skip the initial screen of the called program and that screen contains obligatory fields.
If you want to set SPA/GPA parameters before a program call, you need to know which parameters are linked to which fields on the initial screen. A simple way of doing this is to start the program that you want to call, place the cursor on the input fields, and choose F1 followed by Technical info. The Parameter ID field contains the name of the corresponding SPA/GPA parameter. Alternatively, you can look at the screen definition in the Screen Painter.
The SPA/GPA parameter for the input field Company has the ID CAR. Use this method to find the IDs CON, DAY, and BOK for the other input fields.
The following executable program is connected to the logical database F1S and calls an update transaction:
REPORT BOOKINGS NO STANDARD PAGE HEADING.
TABLES SBOOK.
START-OF-SELECTION.
WRITE: 'Select a booking',
SKIP.
GET SBOOK.
WRITE: SBOOK-CARRID, SBOOK-CONNID,
 SBOOK-FLDATE, SBOOK-BOOKID.
HIDE: SBOOK-CARRID, SBOOK-CONNID,
 SBOOK-FLDATE, SBOOK-BOOKID.
AT LINE-SELECTION.
SET PARAMETER ID: 'CAR' FIELD SBOOK-CARRID,
 'CON' FIELD SBOOK-CONNID,
 'DAY' FIELD SBOOK-FLDATE,
 'BOK' FIELD SBOOK-BOOKID.
CALL TRANSACTION 'BOOK'.
The basic list of the program shows fields from the database table SBOOK according to the user entries on the selection screen. These data are also stored in the HIDE areas of each line.

Memory Problem with SEt and GET parameter

hi,
I m doing exits. I have one exit for importing and another one for changing parameter.
SET PARAMETER exit code is ....
*data:v_nba like eban-bsart,
       v_nbc like eban-bsart,
       v_nbo like eban-bsart.
       v_nbc = 'CAPX'.
       v_nbo = 'OPEX'.
       v_nba = 'OVH'.
if im_data_new-werks is initial.
if im_data_new-knttp is initial.
    if im_data_new-bsart = 'NBC' or im_data_new-bsart = 'SERC' or im_data_new-bsart = 'SERI'
       or im_data_new-bsart = 'SER' or im_data_new-bsart = 'SERM' or im_data_new-bsart = 'NBI'.
      set parameter id 'ZC1' field v_nbc.
    elseif im_data_new-bsart = 'NBO' or im_data_new-bsart = 'NBM' or im_data_new-bsart = 'SERO'.

    endif.
endif.
endif. *
and GET PARAMETER CODE IS....

get parameter id 'ZC2' field c_fmderive-fund.
get parameter id 'ZC3' field c_fmderive-fund.
FREE MEMORY ID 'ZC1'.
FREE MEMORY ID 'ZC2'.
   FREE MEMORY ID 'ZC3'.
In this code i m facing memory problem.
It is not refreshing the memory every time.
So plz give me proper solution.
Its urgent.
Thanks
Ranveer

Hi,
   I suppose you are trying to store some particular value in memory in one program and then retieve it in another.
If so try using EXPORT data TO MEMORY ID 'ZC1'. and IMPORT data FROM MEMORY ID 'ZC1'.
To use SET PARAMETER/GET PARAMETER the specified parameter name should be in table TPARA. Which I don't think is there in your case.
Sample Code :
Data declarations for the function codes to be transferred
DATA : v_first TYPE syucomm,
       v_second TYPE syucomm.
CONSTANTS : c_memid TYPE char10 VALUE 'ZCCBPR1'.
Move the function codes to the program varaibles
v_first = gv_bdt_fcode.
v_second = sy-ucomm.
Export the function codes to Memory ID
EXPORT v_first
       v_second TO MEMORY ID c_memid.        "ZCCBPR1 --- Here you are sending the values to memory
Then retrieve it.
Retrieve the function codes from the Memory ID
IMPORT v_first TO v_fcode_1
         v_second TO v_fcode_2
FROM MEMORY ID c_memid.                                   "ZCCBPR1
FREE MEMORY ID c_memid.                                   "ZCCBPR1
After reading the values from memory ID free them your problem should be solved.
Thanks

Set and get parameter id

Hi,
I need to store one variable value and I need to retrieve the same variable value in same program. For this I have written set and get parameter ids in the same program. It is working fine but if I log off the system and if I logon the system it is not working I mean before log off the variable is showing some value if I log on again that variable is showing empty. But I want to capture the field values after log off and log on also. Is there any other option can I use table?
Please help me I will give points.
Thanks.

Hi
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens
SAP global memory retains field value through out session.
set parameter id 'MAT' field v_matnr.
get parameter id 'MAT' field v_matnr.
They are stored in table TPARA.
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
ABAP memory is temporary and values are retained in same LUW.

Which difference between a PChar parameter and OCIString parameter ?

Hello, I have some questions concerning the external procedures under Oracle 9i :
Which difference between a PChar parameter and OCIString parameter ?
When does one use PChar?
When does one use OCISstring?
In a wrapper, can one declare a parameter with a default value?
Thanks in advance.
Laurent Dardenne

The rows retrieved from the database are filtered, if you define
a parameter. You can see the parameter conditions getting added
to the SQL, when you view the sql with sql inspector.
On the other hand, with the page item, the filtering does not
take place at the database level but at the discoverer level.

Okay, first you will need to setup time machine to backup your system to the new hard drive. Just open time machine and turn it on, then select your new hard drive and time machine will start the backup in a few minutes.

How set and get parameter for a session of a portlet (Java)

I would like get parameter and set parameter for a portlet in portal 9.02. This parameter must be availbale during the session of the portal.
With Java Servlet
// I retrieve my session
HttpServletRequest httpreq = (HttpServletRequest)req;
HttpServletResponse httpresp = (HttpServletResponse)resp;
HttpSession session = httpreq.getSession();
//And after i can get or set some parameter for this servlet
//Example
session.setAttribute("MyEmployeeNumber","600000");
String id = (String)session.getAttribute("MyEmployeeNumber");
// But with Portlet in portal, i can't do it.
PortletRenderRequest pr= (PortletRenderRequest)httpreq.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
String sUser=pr.getUser().getName();
ProviderSession session=pr.getSession();
// But after if i want get or set a value in this session i have a internal error 500
session.setAttribute("MyEmployeeNumber","600000");
I would like my parameter is avalaible during a session for a user in each page of the portal, because my portlet is on each page.

I have almost the same problem. I tried as you suggested, but it doesn't work yet.
provider.xml
<session>true</session>
<passAllUrlParams>true</passAllUrlParams>
My code in my jsp-portlet is
<%@page contentType="text/html; charset=windows-1252"
import="oracle.portal.provider.v2.render.PortletRenderRequest"
import="oracle.portal.provider.v2.render.PortletRendererUtil"
import="oracle.portal.provider.v2.http.HttpCommonConstants"
import="oracle.portal.provider.v2.ParameterDefinition"
import="oracle.portal.provider.v2.render.http.HttpPortletRendererUtil"
%>
<%@page session="true"%>
<%
PortletRenderRequest pReq = (PortletRenderRequest)request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
String valueSession = (String)pReq.getAttribute("sesion");
if (valueSession != null) {
pReq.setAttribute("session", "value1");
out.println(" (1)valueSession != null");
out.println(" (1)valueSession : " + pReq.getAttribute("session"));
} else {
pReq.setAttribute("session", "value2");
out.println(" (2)valueSession == null");
out.println(" (2)valueSession : " + pReq.getAttribute("session"));
%>
And i always get as result:
(2)valueSession == null
(2)valueSession : value2
Even when i send values (post) at the same page or browsing between tabs:
I check my provider registration and it has the value "once per session"
I have portal 9.0.2.2.14
Thanks

SAP Memory, Set and Get parameter

Hi All,
     I am running two programs in background from program1
Eq: Program1 --> Calls 2 programs
                          Program1_01.(First Program)
                          Program2_01(Second Program).
Programs1 schedules Program1_01 and Program1_02 in background. These two programs are interdependent.
Program1_01 extracts data, evaluates and sets the Flag. This Flag is exported to SAP Memory using
Set parameter id 'p_id_flag' field Flag.
Program1_02 checks for Program1_01 is completed in background. If complted gets the Flag value from SAP Memory using "Get paramter id 'p_id_flag' field Flag.
When i checked this is not happning. When saw Flag in Program1_01 is set as Flag = 'X'.
When I came and checked in Program1_02 after Get Parameter statement Falg value is SPACE.
Cn hlp on this?

Hi,
The problem simply lies in fact that pid was provided in lowercase.
Use:
SET PARAMETER ID 'P_ID_FLAG' FIELD flag.
GET PARAMETER ID 'P_ID_FLAG' FIELD flag.
It works fine then.
Note!
Though SAP claims it is mandatory to create pid in TPARA table, in fact this is not required. Each time SET PARAMETER is executed, system checks if data object P_ID_FLAG was defined in SAP memory. If not it will automatically create it for us. But be carefull here. If there is such data object, its value will be overwritten.
As for your last question, your statement (FREE MEMORY ....) is ok.
Regards
Marcin

What's the difference between reference parameter and value parameter.

hey,expert
what parameter is reference parameter?
when I made the import in RFC function,the message as follows:
You have defined a reference parameter for a remotely called function module. However, only value parameters are allowed in this kind of function module.
can any expert tell how to solve this problem?
thank you.
kim heum

A reference parameter : When a parameter is called by reference, the system points to the original parameter without making a copy of it. The function module works with and, if necessary, alters the original parameter and not a copy.
Make the parameter you have defined as "pass by Value".. There is a checkbox in the inteface definition for that..

How to set Processes and Session parameter

Hi All,
I have to check the optimal value for the Parameter "processes" and "session" for my database server,
existing value for Processes is 500 and sessions is 1000.
Oracle application: 12.0.6
database 10.2.0.4 2 node RAC.
and i wanted to know how many " jdbc connection" can be done for the 12GB RAM and Quad core two CPU machine,
Pl let us know any doc/Thumb rule to set the above.
Thanks and Regards
Vasu

Hi,
I wanted to check what is the maximum limit of the "processes" for my existing resource. is my 500 processes itself is exhasted the resources.The maximum limits are mentioned in the database reference manual.
Process and Runtime Limits
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/limits004.htm#i288165
Oracle 10g Documentation Library
http://www.oracle.com/pls/db102/homepage
Kindly let me know any SQL query or supporting document to set the processes and session parameters.Did you review the initialization document referenced above? I believe it shows the value you need to set for processes and session parameters. For the query, you can query v$parameter or issue "show parameter <parameter name>" from SQL*Plus.

NTFS-3G - Help setting up, and getting rid of .DS_Store files

Hello All,
I'm new to the Mac world so please bare with me. I installed this last night using a video from CNET on youtube, but the final command line they gave didn't work. I eventually mounted the disk and it seemed to work, however there were strange files and folders on the disk when I went back into Vista.
So I reinstalled everything and now I'm ready to try it again.
Could someone please give me a step by step way (step 1. Install Mac Fuse) of setting up Ntfs-3g and any command lines or anything I would need to use. Call me lame, but I don't understand the instructions as I keep finding different ones everywhere I look.
Secondly, could someone explain why I keep getting .DS_Store files and similar ones like that when I navigate into Windows? I realize these must be Mac system/meta files, but they're clogging up everything. Is there a way to either have them not be written, or be hidden/cleaned by vista.
Thanks for your help!
Jeff

actually, what would work awesome as well is a single directory where I could just put the files in that I need or want to modify....that would be another cool option if anyone knows how.

"Changing" parameter and "Tables" parameter defintions in function module

If one defines "Changing" or "tables" parameters, they are treated as reference parameters.
It becomes obvious for "tables" parameters where one does not have option to check box for "Pass by Value". But for "Changing" parameters, they provide the checkbox for "Pass by Value". Even when you select this option, the function module seems to handle the parameter as a reference parameter (whatever changes you make to it in the function module are retained when you return back to a calling program).
My question is why then SAP has provided the checkbox of "Pass by Value" for "Changing" parameter?
Thanks.
Jitendra Mehta

Hi Chaiphon:
Thanks for explanation but I know the theory of "Pass by reference" versus "Pass by Value".
Let me rephrase my question.
When I use the importing parameter (say as a table with a dictionary table type) with reference (not "passing by value"), and if I modify the value of the parameter, the calling program (which calls function module) receives the changed value after the call.
When I use the importing parameter with "Pass by Value" box checked, the modifications made to the table inside the function module is not retained after the code leaves function module and returns to the calling program.
My question is why not the same behaviour with the "Changing parameter" in function module definition?
And if Changing parameters are always reference parameters, then why SAP has provided the "Pass by Value" check box?

How to use SET BIT and GET BIT in ABAP Programming

Hi,
Our team is currently working for an Upgrade project which is using a tool automatically upgrades when we supplly the code. fine, But now the requirement is , we need to write different test cases for the available key words in ABAP. Now we r looking for the usage of " BIT ", keyword. so , kindly provide any program or code using this key word.
Please find the description Provided and give some relative ABAP code to satisfy the given description.
The data object byte_string must be byte-type. The statement reads the bit at the bit position BITPOS of the variable byte_string and assigns its value to the variable val. A default mode can be specified if required *
Thanks & Regards,
P.N.Kumar.

What on earth are you testing? That ABAP still works? I think SAP might have run that through rigourous testing themselves.
If you want sample code, why not read the ABAP help, and work some out for yourself?
