How to know whether a TCode is called directly or not

Hi all,
I have a requirement to create a popup in a standard TCode. This TCode is recorded to BDC and used in another report.
I would like to know how we can check (in code) whether the standard Tcode is being called directly or it is being called by a different program, function module or bdc ...
Thanks,
Khanh

Hi,
It can be checked in the following way:
IF sy-calld IS INITIAL.     
ENDIF.
" sy-called is initial if the program is run stand alone. If it called from another program, it is not initial.
Thanks & Regards

  • How to know whether balance carry forward has happened or not

    How to know , whether balance carry forward has happened or not for a perticular GL account or for the company code as a whole?

    If the account is a balance sheet account, you can merely look at the beginning balance for the same balance sheet account for the beginning of the next fiscal year FS10N. The beginning balance will equal the previous year's ending balance. Since this does not happen automatically, you will know that carry forward has not been done if a balance sheet account has no beginning balance in the following fiscal year.
    If you are talking about For P&L GL accounts, you can check the acvitity in the retained earnings accounts to make sure that they have been updated for the P&L activity. You can identify the retained earnings account by looking at the master data for the account in the section "P&L statmt acct type" and pulling up the menu to see the actual retained earnings account number.
    You can perform carry foward (GVTR) as many times as you want but normally once it has been ran, any postings to a  previous fiscal year are automatically carried forward to the current year after that initial run.

    Trust me - I've been developing on an XP box for years and Java 1.6 for a good amount of time. This has been using Tomcat, JBoss, and Glassfish (and I try hard to forget about Oracle OC4J). These are application servers that implement part (Tomcat) or all (the rest) of the J2EE specification.
    Having said that, you'll want at least 2GB of RAM and a hundred or so megabytes of disk space. Less RAM will work but slowly. A reasonable processor (I'd say at least 1.5GHz or above) will speed development.

  • How to know  Whether Partition is done for Cube or not

    Hi All,
    I need information regarding Partition of a cube.
    a)How do i know the Partition is done or not for Cube
    b)On what basis we should make parttion of Cube.
    Thanks and Regards,
    C.V.

    There are several threads on partitioning, so it would be a good start for this question (as with any question) to search the BI forums on "Partitioning" and review thsoe first.
    Some basic considerations on partitioning -
    - Your DB must support Range partitioning to permit partitioning your InfoCube. The option will be greyed out if it is not available.
    - InfoCube must be empty to be partitioned.
    - InfoCube can only be partitioned on 0FISCPER or 0CALMONTH.  You can define it so that you have a partition for each month/fiscper, or so that each partition will hold a few or several months of data.
    - Generally, you would not partition small cubes.
    - Thru BW 3.5 Aggregates automatically get partitioned the sme way the InfoCube is partitioned as long as the partitioning characteristic is in the aggregate.  In 2004s, I believe you have options as to whether an aggregate gets partitioned or not.
    - Partitioning may be done for query performance reasons and data administration.  If the queries on the InfoCube regularly run with restrictions/filters on the partitioning characteristic (FISCPER or CALMONTH), the database will "prune" any partitions that do not contain the FISCPER/CALMONTH value(s), so that it does not need to consider them , e.g. most of your users only run a sales query for the current and previous month, but your cube contains 3 years of data.  By partitioning on CALMONTH (we'll assume 1 partition / month), the database will exclude all but the two partitions from consideration.  This could help query performance a lot. or maybe only a little, depending on a variety of other factors.
    Again - it is important that the queries restrict onthe partitioning characteristic to be of any value on query performance.  So don't partition on FISCPER if all the queries use CALMONTH for restrictions.
    The data adminsitration reason you might partition is to improve selective deletion or archiving time.  These processes are capable of using a DB function to Drop the partition, which quickly removes the data from the cube, rather than having to run a resource intensive Delete query.  This only happens if you deletion/archiving criteria is set to remove an entire partition of data.
    Again - review the other threads on the BI forums on Partitioning.  Most questions you have will already have been asked and answered before, and post again on SDN if there is something you still have a question about.

  • How to know whether data is being AES crypted or not?

    Hi Forum,
    I used AES crypting with an initial vector and a SecretKey.
    The problem is , for backward compatibility I need to check if the data had been crypted or not?
    if not crypted I need to show them in plain readable format instead of decrypting them.
    below is my Encryption/Decryption class

  • How to know whether the Content Type at Library level is Inheriting Parent Content type or not Using Powershell?

    Hi,
    How to know whether the Content Type at Library level is Inheriting Parent Content type or not using Powershell?
    Is there any property for that? Or Do I need to compare the Content type Id's at Site collection level and Library level?
    Any help would be greatly appreciated.
    Thank you,
    AA.

    Hi Ashok,
    For a content type, there is an attribute called Inherits, the value of this attribute determines whether the content type inherits fields from its parent content type when it is created.
    If Inherits is TRUE, the child content type inherits all fields that are in the parent, including fields that users have added.
    If Inherits is FALSE or absent and the parent content type is a built-in type, the child content type inherits only the fields that were in the parent content type when SharePoint Foundation was
    installed. The child content type does not have any fields that users have added to the parent content type.
    More information, please refer to the link:

  • How to identify whether a TCode is for SAP query or for a customized TCode

    Hi,
    We have a list of TCodes starting with Y_*
    Some of these TCodes could be related to SAP Queries and some could be real custom transactions. How do I find out which one of those are related to SAP queries and which ones are related to custom SAP transactions?
    I have already checked table TSTC for the program names of these Transactions, but the program name field (PGMNA) is blank. Also in TCode SE93 the transaction mentioned is START_REPORT. Also for some, when I go to the transaction (Y_*) and then environment->status to check the program name the values found are something like AQ11FI==========F10A==========.
    Please help on how to identify whether a TCode is actually for an SAP query or for a customized transaction.
    Thanks in advance.
    Mick

    Thanks Anil.
    In TSTC, the filed for program name is blank. Therefore I would have to go to each and every transaction (I  have around 250 Y_* TCodes with me) and then to environment->status to get the program name and then check whether it is A......
    Is there any easier way to know whether a TCode refers to an SAP query or a custom developed transactions/program.

  • How to know whether the javascript is disabled or not while loading the jsp

    Hi,
    My query is like how to know whether the javascript is disabled or not while loading the Application main JSP in Mozilla browser.
    I want some Java code or JavaScript code.

    To the point, just let JS fire a specific HTTP request inside the same session.
    This can be done in several ways. 1) Create a hidden <img> element and set the `src` attribute so that it will request a (fake) image from the server. The server just have to intercept on this specific request. 2) Fire an ajaxical request and let the server intercept on it. You can use a Filter for this which sets a token in the session scope to inform that the client has JS enabled.

  • How to know whether a method is thread-safe through the java-doc?

    In some book, it says that SAXParserFactory.newSAXParser() is thread-safe,but in the java-doc,it doesn't say that.
    newSAXParser
    public abstract SAXParser newSAXParser()
    throws ParserConfigurationException,
    SAXExceptionCreates a new instance of a SAXParser using the currently configured factory parameters.
    Returns:
    A new instance of a SAXParser.
    Throws:
    ParserConfigurationException - if a parser cannot be created which satisfies the requested configuration.
    SAXException - for SAX errors.
    I want to know, how to know whether a method is thread-safe?

    System.out is a PrintStream object. None of the methods there use the synchronized modifier, but if you look in the source code, you will find out it is thread-safe, because it will use synchronized blocks whenever it writes some text.
    The source code is in the src.jar file which you can extract.
    I didn't find any comments about that PrintStream is thread-safe in the API.

  • How to know whether the current database is using a password file or not?

    How to know whether the current database is using a password file or not?

    The remote_password_file is the parameter that determines if you can use or not a password file. The values this parameter can have are NONE, SHARED, EXCLUSIVE. It is pretty obvious, if it is set to either SHARED or EXCLUSIVE the oracle instance has enabled the access through a password file for the SYSDBA and SYSOPER roles.

    depends on the O/S you are using, Unix or Windows? I would use Korn shell script to monitor the Oracle background process and scripts to check of Oracle is accepting connections.
    This UNIX command will show the number of processes for your instance:
    ps -ef|grep $ORACLE_SID|grep -v grep|grep -v ora_|wc u2013l
    In Windows I would look into services.msc
