How to make a key field manadatory, in a Z-Table (SE11)

Hi,
I've created a Z-table is se11 and one of the key fields is IWERK. Now the user does not want this field to be blank when they enter data into the table via SM30.
Does anyone know how to make this field so that a blank entry is not acceptable.
Many Thanks!

Hi Robert!
One way would be to adjust SM30 to a mandatory field (in SE11 of course), but this field sounds like you can assign T001W as a check table. In the foreign key definition, you can give a error message, which is called in case of wrong entries in screens -> there is no empty entry in T001W, you can only maintain valid values and got a value list.
Regards,
Christian
P.S.: No, you need to change SE11->Table maintenance generator->Enviroment->Modification->Maintenance Screens->Element list->Tab Special attr. column Input. Set 'required'. Otherwise empty is still allowed

How to make Sales Office field mandatory in VA01 initial screen?

Hi,
How to make Sales Office field mandatory in VA01 initial screen? I mean in the first screen where we enter the document type and the sales area?
Regards,
Ajit

Dear Deepak,
Thanks for the clarification.
But, as far, I have understood the query - it is very simple and that is..
Whenever one creates a Sales Order (T.Code: VA01), Parameter: Sales Office needs to be mandatory (for all Sales Order, irrespective of Customer Account).
Until-unless, user won't enter the parameter: Sales Office, System will not lead to next page (now, here we need to enter Customer/ material etc...).
I have answered the query, in this regards, only.
Best Regards,
Amit.
Note: Pls. correct me, if I am wrong. Thanks for everyones guidance.

How to make valuation type field not changeable in delivery tab of PO

Hai friends,
I am new to badis..please guide me to solve the issue...
how to make valuation type field not changeable in delivery tab of PO...
The field shd be in display mode only ...actually...there a badi has been used before
to get valuation type from a ztable depending on material and plant...
Now ..my requirement is that the user shd not change the default value brought from the ztable...

Hi SRINIVAS,
You can achieve this from BADI only if BADI is allows you to do this. You cannot achieve everything from a BADI. Check if there is any expoting field in the methods that can be ticked for making the field in display mode. If not then you cannot achieve this from BADI.
The field you want to default to display is a standard or zfield. If z, then you can changethe attribute of the screen field to Output only.

Vendor Master Management - How to make 'Corporate Group' field an autoupdat

Vendor Master Management - How to make 'Corporate Group' field an automatically updated field
Frnz,
I am doing a Spend Analysis and thereby restructring some aspects of SAP and business processes. One of the intiatives is to leverage the 'Corporate Group' field in Vendor Master for getting the consolidated spend visibility at the corporate group level of vendors. So far this field wasn't been used to effect. I can update it manually, but the question remains is how do I do with the change management of the corporate group of large vendor base in the scenario of everhappening Mergers and Acquisitions. Are there any alternatives anybody can suggest ? (Like linking D&B numbers etc)
Thanks in advance for your suggestions..

Hi Shiv,
Let me elaborate the purpose of using this field. I want to have a consolidated spend visibility across a corporate group which has multiple vendor codes. Its difficult everytime to group the spends of these vendors manually especially when the number of vendors are too high. Also sometimes the names of vendor companies may not indicate that these are from same corporate group but in fact they could be. In order to have the reports generated on corporate groups, I must maintain this field in vendor master or a Z table. But the problem here is, it should be possible to update this field as and when there are any mergers or acquisitions at vendor side and the corporate group of a particular vendor gets changed due to this. So this has to be effected in vendor master or Z-table automatically. I do know that there are certain agencies like Dunn & Brad (DNB) which provide possibly the details on corporate group of a company but its not fully effective for Indian Vendors as its not mandatory on them to have DNB number & also its a disconnected process and I was looking to connect it seamlessly to Corporate Group field so that I need not bother to update these things manually everytime. I also wanted to explore various possibilities of doing this.
I hope I have spelled it out correctly.

How to set a key field in a local provider for BW workspace

Hi Experts,
I've created a local provider through BOBJ analysis for excel / Workspace designer in a BW workspace. However, all the dimensions by default are not having the key field enabled and I'm not able to enable the key field through BW workspace. Also I see the Fact Index Without Key is enabled by default in technical settings, which is not allowing me to select "Fact Index with Key" either. When I go to edit mode, it says "Analytic Index XXX can only be changed in workspace designer". I even tried to go into workspace designer and by selecting the necessary local provider, I coudn't find an option under Local Provider->Reload Provider->Reload (With Changes)->Choose File->Edit Columns to enable the key field(s) for the dimensions.
Can you please help to locate how to enable the key field for dimensions in local provider.
Thank you in advance.

How to make a key out of this data?

Since no one replied to my last post, I'll give it another try. From an RTSP server I get two values, a key called rsaaeskey (342 bytes, without the line breaks):
yxKBocBgTii20n9nbKfYGyGhPqtosXuq8M99yU5/PzTVNmIUsUGlpD27u

K3Z6FK7XVnfehYYJjRw7THMZzSvq7FtLB9QgulqQTJ3awJdwS0ACb1FkAand an initialization vector called aesiv (22 bytes):
zcZmAZtqh7uGcEwPXk0QeAThe data is obviously Base64 encoded. However, after decoding I don't know how to make a key out of it. Trying KeyFactory's generatePublic and generatePrivate methods result in an InvalidKeySpecException with any algorithm I've tried (RSA, DSA, DH).
I think this is a multi-prime RAS secret key (someone said they're 342 bytes long), but how do I generate a Java Key out of it?

The rsaaeskey, decoded to binary, is a binary array of 256 bytes. Using the DUMPASN1 tool we see that the bytes are not in ASN.1 BER or DER encoding.
C> openssl enc -base64 -d -in rsaaeskey.base64 -out test.bin
C> dumpasn1 rsaaeskey.bin
   0 CB   18: [PRIVATE 11]
            :   81 A1 C0 60 4E 28 B6 D2 7F 67 6C A7 D8 1B 21 A1
            :   3E ABIf it were encoded in ASN.1 BER or DER encoding it will start as a "SEQUENCE" or a "SET", not as an unrecognized data.
You need to check the exact specification of the protocol. (Are you using TSP - RFC 3161, or RTSP - RFC 2326?)

How to make few columns of single record inactive in Table conrol?
Thanks in advance.

hi there...
select the column that u want to convert to non editable mode in the screen layout. then double click on it. go to the attributes tab and uncheck the input chk box. the check box will become disabled for input. u can do this for any number of columns.
if u want to do it dyanamically, loop at screen. check for the screen element's name. when itmatches the column u want to disable, simply set the input value as 0.
dont forget to modify sscreen after setting the attribute values.
i hope this helps.

How to make a row as selected in output internal table in oops ALV

Hi All,
I have ALV grid output using oops ALV concept, in my output i have a checkbox as first column when i select this checkbox and press a push button 'Print' which is there above ALV grid that particular line in output table should get selected and i need to code some logic for printing selected row.
how to make the particluar row in the output internal table to be selected and where to write the logic for print once it is pressed?
Thanks in advance
Srilakshmi.

but the checkbox is not getting set in internal table when i select some checkboxes.
can anybody explain y the checkbox in internal table not set?
Hi Srilakshmi,
As explained by Uwe, when we change a field ( say check box ) in ALV grid, the view (frontend) changes (showing the tick mark) but the changed data ( normally ) is not transfered to the backend.
We can initiate this data transfer by just registering the cl_gui_alv_grid=>mc_evt_modified edit event
go_grid->set_table_for_first_display( CHANGING it_fieldcatalog      = pt_fieldcat
                                                  it_outtab            = pt_outtab ).
go_grid->set_ready_for_input( 1 ).
go_grid->register_edit_event( EXPORTING i_event_id = cl_gui_alv_grid=>mc_evt_modified ). " This does the trick
Now as soon as we check a checkbox, the data_changed event is triggered.
This initiates data transfer to the backend and the checkbox field in internal table is updated.
check the below code for example.
DATA: go_cont            TYPE REF TO cl_gui_custom_container,
      go_grid            TYPE REF TO cl_gui_alv_grid,

How to add one more field to an exist internal table

hi abapers
i am a very new abap programmer and just started learning it.
i want to know How to add one more field to an exist internal table.
lemme me put my question in a very simple way.
i have a internal table having fields f1,f2,f3 and which also that internal also contains some data.
now i want to add two more fields (mm & nn) to that internal table now.
how can i do that.
and i wanna know the websites names where i can find some brain teasing questions in abap programming.
eagerly waiting for ur reply
regards,
Maqsood A Khan

Hi, MAQSOOD.
You can insert more fields in your internal table like this.
refer this code snippet.
DATA : BEGIN OF tbl_itab OCCURS 0.
        INCLUDE STRUCTURE zsdtc009.
DATA : vkorg   LIKE vbak-vkorg, "inserted one
        vtweg   LIKE vbak-vtweg, "inserted one
        vkbur   LIKE vbak-vkbur, "inserted one
        vkgrp   LIKE vbak-vkgrp, "inserted one
       END OF tbl_itab.
you can also read the book "Teach yourself abap in 21 days"
at http://cma.zdnet.com/book/abap/
but that book is just about basic concept of abap and report program.
it doesn't give a lecture for on-line program.
you can get pdf version books(about abap, sap...things) from sap.
http://help.sap.com/printdocu/core/Print46c/en/Data/htm/english.htm
I wish I could help you.

How to make added custom field Delta mechanism work for LO Cookpit?

We appended a new custome field into extraction structure of the LO Cookpit datasource 2LIS_02_ITM through RSA6. And then run CMOD to write the exit code to populate the value and it works fine. But after we read Roberto's Weblog:
/people/sap.user72/blog/2005/02/14/logistic-cockpit--when-you-need-more--first-option-enhance-it , find the enhancement we did can't make the Delta mechanism works if only this new field gets changed in a record, and the change cannot be reflected on BW.
In order to make the Delta mechansim works, one option is to append the custom field into one of the LIS Communication Structure MCEKKO of 2LIS_02_ITM extraction structure and then write the enhancement code to this LIS Communication Structure. In this way, the custom field can be treated like standard field that whenever it gets changed, the Delta mechanism or the user exit will be triggered. The enhancement for this LIS Communication Struture is LEINS001.
Now we've got two problems when doing the above enhancements of the LIS Communication structure:
1. Maintain extraction structure problem in LBWE:
We added a custom field, e.g., called ZZZ in LIS Communication structure MCEKKO (Purchasing Document Header) by creating a new custom append structure and add the field ZZZ into it, then activate the new append structure, but get warning msg like "Field name DUMMY is reserved (Do not use structure as include in DB table)".
We do find a field called DUMMY in the structure MCEKKO. How to get rid of the warning msg and successfully activate the new custom append structure with the new field ZZZ?
You could say that we can ignore the warning msg, but why the new custom field appended can not be seen from the right side pool of the Maintain Extract Structure in LBWE? We need to make the new custom field shows up in the right side pool and then drag it over to the left side frame and to activate the extraction structure to change it. But now it doesn't show up in the right frame pool!
2. Refer to Sanyam's weblog
/people/sanyam.kapur/blog/2005/04/30/custom-fields-and-bw-extractors-making-a-mixed-marriage-work-part-ii, there is a sample code inside this article which tells us how the sample code looks like to write this LIS Communicaton structure enhancement to make the Delta mechanism works, below is the code we modified to suit our needs, but don't know if it would work?
DATA: i_t_ekko LIKE ekko   OCCURS 1 WITH HEADER LINE.
DATA: ebeln LIKE ekpo-ebeln,
      it_ekko TYPE TABLE OF ekko WITH HEADER LINE,
      old_val(50) TYPE c. "For storing the value from the Field Symbol
FIELD-SYMBOLS <fs> TYPE ANY TABLE.
CASE zeitp.
WHEN 'MA'.                            "When creating a purchase order
    MOVE '(SAPLEINS)T_EKKO[]' TO old_val.
    ASSIGN (old_val) TO <fs>.
    i_t_ekko[] = <fs>.
    LOOP AT xmcekko.
      ebeln = xmcekko-ebeln.
      IF xmcekko-supkz = '1'.            "Old Value ?
        SELECT SINGLE * FROM ekko INTO it_ekko WHERE ebeln = ebeln.
        xmcekko-ZZZ = it_ekko-ZZZ.
      ELSE.                              "New Value ?
        READ TABLE i_t_ekko WITH KEY ebeln = ebeln.
        xmcekko-ZZZ = i_t_ekko-ZZZ.
      ENDIF.
      MODIFY xmcekko.
    ENDLOOP.
EndCase.
Share your ideas and we will give you reward points!

Hello Kevin
We have exactly the same problem. Did you solve it? If you did, could you please tell us how you did it? We neither see our field in LBWE. Our field is a Z field from a Z table.
I hope you could help us. We just have this issue to finish our project.
Thanks a lot in advanced
