Calling custom tcode in HAP_DOCUMENT_LINK

HI Experts,
I have req that i want to call my custom tcode in standard webdynpro component HAP_DOCUMENT_LINK. Actually i have a table in HAP_DOCUMENT_LINK with link, when user click on link i want to display my custom t-code.
I have created a custom webdynpro component which contains ALV table, When i execute that component it display empty rows with editable mode, i have created t-code for that webdynpro component like ZTABLE ( tcode name of wd component ) i want to call this tcode by filing all records and display it in read only mode. please help me to solve this .
Regards
Syed

Hi Syed,
You will just pass the key information via URL parameters to your custom web dynpro application. I think for your requirement you no need to create t-code, you launch the url directly.
Please refer the below links
Calling one webdynpro application from another | Webdynpro ABAP
Read URL Parameters in Web Dynpro ABAP
The above links clearly explains how to call one web application in other component and pass the url parameters.
Process can be divided as below:
Enhance the standard component, use POST EXIT and call the URL of Zcomponent and pass the parameters
Go to eventhandler method "HANDLEDEFAULT" of window of zcomponent and read the url parameters
Now, Based on the above parameters, you can populate the data into alv table in custom component
Also, make the alv as read only by using method if_salv_wd_table_settings~SET_READ_ONLY( abap_true)
Hope this helps you.

Rama

Baseline date mesg not appear when call transaction FB60 in custom tcode

Hi Experts,
One of the custom tcode which calls the standard tcode FB60.
If we give the last month date in payment date, it should shows the 'Due date is in the past' message and if we give next year as payment date i.e, more than 365 days, then show 'Baseline date foe pmnt is 700 days after the document date : check'.. These messages are coming when we call the standard tcode FB60 directly.
But if call it in the custom tcode, these messages are not appear.
Thanks,

Custom TCode for Excel File Upload/Import - WebGUI Error

We get an ABAP runtime error when uploading an excel file with a custom tcode using WebGUI. It works ok with WinGUI. Any ideas what could be causing that error?
Runtime Errors         RAISE_EXCEPTION
Date and Time          01/05/2011 17:27:16
Short text
     Exception condition "JAVABEANNOTSUPPORTED" raised.
What happened?
     The current ABAP/4 program encountered an unexpected
     situation.
What can you do?
     Note down which actions and inputs caused the error.
     To process the problem further, contact you SAP system
     administrator.
     Using Transaction ST22 for ABAP Dump Analysis, you can look
     at and manage termination messages, and you can also
     keep them for a long time.
Error analysis
     A RAISE statement in the program "C_OI_CONTAINER_CONTROL_CREATORCP" raised the
      exception
     condition "JAVABEANNOTSUPPORTED".
     Since the exception was not intercepted by a superior

Smartforms:Can i call a Tcod from Driver Prg 4 its o/p 2 be appended

Hello Smartform Gurus
I need 2 call 1 tcode from my Driver prog ,which has report o/p that is 2 be appended in my Smartform o/p as a
appended page .
Is it possible at all ?
plz throw some light on this .
thnx
Moni

Hi Moni,
of course there are several ways to reach your goal.
I have assumed:
- your smartform is based on a SAP-document
- document output is based on standard output determination with output messages
This is defined in customizing (SPRO) at several places or combined in NACE.
Anyway, create additional output just after smartform output, take care of same printer, spool name and so on -> you will end with one (combined) spool request.
Have a look for output messages, if you are unsure how to get a 'simple' smartform output.

Christian

To Add Custom Tcode in SAP Menu

Hi ,
I want to edit the standard SAP menu in sap easy access screen and need to add one custom transaction.
Under the sap menu:
Logistics --> Sales and Distribution --> Shipping and Transportation > Post Goods Issue> Custom Tcode
Anyone please let me know,how to get this done.
Thanks in advance,
Savitha

Hi,
Creating your own SAP Customized Main Menu
You can add additional menu transaction in the SAP main menu without affecting the original SAP default area menu S000.
For example, you have created a transaction code called ( z123 - ABC Own Report ) and you want to insert it under Logistics. The specific user will be able to access ABC Own Report by clicking Logistics -> ABC Own Report.
Steps :-
Goto Transaction SE43 - Area Menu
Click the copy button. Copy from S000 to ZXXX
After copying, click Change (area menu ZXXX)
Double click on Logistics and add in your transaction code in the AreaMenu.
Remembers to Activate it.
Next Goto Transaction SU01 - Maintain users
Type in the user name and click the Defaults button
Type in the area menu (ZXXX) in the Start Menu field.
Click Save
The user will be able to see the additional transaction on the next logon.

Custom Tcode Authorization Error

Dear Security Gurus,
We are getting an authorization while testing Custom Tcode. This tcode is used for Uploading data.
The authorization error shows missing Activity field value and a field called Operating Concern.
The SU53 and the Trace(ST01) show the same error even though the role that is assigned to the user has exactly the required values.
Also Authority Check in the Program of the tcode is maintained for only the Activity field and Operating Concern field.
Hence we are unable to figure out why the auth. issue occurs even though the role assigned to the user has the missing values
Please let me know how I can resolve this authorization issue.
Regards,
Arjun

Hi ,
Below is the Authority check section of the tcode :
START-OF-SELECTION
PERFORM F_AUTHORIZATION_CHECK
    AUTHORITY-CHECK OBJECT 'YTIPRC01' ID 'CEERKRS' FIELD P_ERKRS ID 'ACTVT' FIELD '01'
PERFORM UPLOAD_DATA
    CALL FUNCTION 'GUI_UPLOAD'
      AUTHORITY-CHECK OBJECT 'S_GUI' ID 'ACTVT' FIELD '60'
Even though I have the ACTVT value 01 and the corresponding CEEKRS (Operating Cncern ) Value in the role I still get the error.
Thanks,
Arjun

How to attach a Function Module to a custom Tcode

Hi All,
I need to attach a Function Module to a new custom Tcode.I tried to create the new Tcode with option Parameter Transaction by giving the Tcode as SE37. But i am not able to give my Function module name as default.
Do you have any idea how to do this.
Plese help me.
Thanks
Manas

Hello Manas,
For example in the first line of your FM you write
call screen 100.
Then double click on 100 number and you found yourself on program of creating screen.
Then you write need to describe your pai and pbo functions and set pf-status.
For example, on the click of some button you execute some function.
In transaction you directly execute operator call screen 100 by specifying
SAPLZTEST screen 100.
One more time: call screen 100 in FM equals call transaction 'zmytcode', which have been created to SAPLZTEST screen 100.
You can see tcode ckm3 and function group SAPLCKM8N
Good luck.

Custom Tcode above SE16N to restrict usage

Our users in production want to do a mass maintenance on view ENT5828 which is built upon table JSTO. I have created a custom Tcode called ZJSTO from SE93 by selecting "Transaction with parameters" option and provided screen field DATABROWSE-TABLENAME with view name ENT5828
and skip selection screen for SE16.
Note that this view allows maintenance. and the objective is to restrict users from giving open access to SE16 or SE16N.
This is working wonderful but I could not do mass maintenance as in ALV grid from SE16N.
I could not do the same thing with SE16N. Could anybody let me know if I could create a custom tcode with SE16N defaulting table name to ENT5828 and disabling this field for editing.
Regards
Kasi

Hi,
You can create the Custom tcode on the SE16N..But this will not restrict from entering the table as in SE16. The difference is SE16 has initial screen with table name selection and next screen as selection screen to select the entries ...where as SE16n has got only one screen for table selection and entry selection.
So it is not possible.
You need to create custom table mainatance program for mass maintainance.

Unable to debug an exit in CALL CUSTOMER FUNCTION 003

Hi Guys,
I have an exit EXIT_SAPMV45A_003 that is called by CALL CUSTOMER FUNCTION 003. I had placed a break point at
CALL CUSTOMER FUNCTION 003 and the debugger stops here but i am unable to debug inside this to reach into
the code in EXIT_SAPMV45A_003 even after setting the system debugging on & Update debugging
ON.
Can someone help me with this?
thanks
Dan

You have to include that Enhancement of that exit in the Project and Activate that project in the CMOD.
The Enhancement for the exit EXIT_SAPMV45A_003 is V45A0003.
Create a project in CMOD
And inclue V45A0003 in the project.
Activate the Project.
Now, it will stop at break point.

Steps to create Customized Tcode in BI

Hello,
I need to create a Customized TCode at BI side for updating texts of certain master data's.
Could you please provide me step by step solution for that problem.
Regards,
Rahul Mahajan

Hi Rahul,
You can create customized T-Code in Bi using transaction SE93.
You need to give the name of the ABAP Program which you need to include in this customized T-Code.
T-Code is nothing but a program which gets executed when you run that specific T-code in command bar.
So what you can do is write a program which will fill your master data and include it ithat program in your T-Code
Thanks and Regards
