"A peak into ABAP"

Hi Gurus!
Since its inevitable to overlook the application part, as I have a series of questions running across
1. What is the difference between a routine and a requirement?
2. What is ABAP debugging? How is it carried out?
3. What is the client specific data?
4. Can a standard user exits be modified by ABAPers?
5. Can we create a user exit? If yes, how?
6. What are the SD related reports we can generated with help of ABAP?
7. What is ABAP query?
8. There are certain fields which turn into display mode once the sales document is created, which we can see them in order document change mode. How can I change the field status? last time some body said it can be done using "transaction varient". suppose if want the "payment terms" at Item level, shipping tab page to be shown in change mode in [VA02]. how? Please explain steps in detail.
All respondents will be rewarded generously.
Thanks in Advance

1. What is the difference between a routine and a requirement?
Routines is generic words which include all the routines defined in VOFM it includes AltCBV, AltCTY..etc, Requirement, it is piece of Code which needs to be fulfilled to consider further processing, for e.g. Requirement 2 checks pricing is activated or not, if it is not activated in item category, it will show requirement is not fulfilled
Pricing is turned on in item category configuration (TVAP)
form kobed_002.
sy-subrc = 4.
if komp-kposn ne 0.
check: komp-prsfd ca 'BX'.
check: komp-kznep = space.
endif.
sy-subrc = 0.
endform.
Prestep
form kobev_002.
sy-subrc = 0.
endform.
2. What is ABAP debugging? How is it carried out?
There are many links you can find
at command prompt put /h and debug will start you can explore your self
http://www.saplinks.net/?p=8
3. What is the client specific data?
Client Specific Data, in table first field is client CLNT , Any configuration in this data will not effect other clients in SPRO
you can view in Additional Information->Technical Data-> Client Specific
4. Can a standard user exits be modified by ABAPers?
Yes but Access Key is required , which is available from SAP
5. Can we create a user exit? If yes, how?
Here we mean whom? user exit can be created, but again access key is required from SAP
6. What are the SD related reports we can generated with help of ABAP?
list of invoice, delivery, sales orders..etc
7. What is ABAP query?

8. There are certain fields which turn into display mode once the sales document is created, which we can see them in order document change mode. How can I change the field status? last time some body said it can be done using "transaction varient". suppose if want the "payment terms" at Item level, shipping tab page to be shown in change mode in VA02. how?

Simple Transformation to deserialize an XML file into ABAP data structures?

I'm attempting to write my first simple transformation to deserialize
an XML file into ABAP data structures and I have a few questions.
My simple transformation contains code like the following
<tt:transform xmlns:tt="http://www.sap.com/transformation-templates"
              xmlns:pp="http://www.sap.com/abapxml/types/defined" >
<tt:type name="REPORT" line-type="?">
<tt:node name="COMPANY_ID" type="C" length="10" />
<tt:node name="JOB_ID" type="C" length="20" />
<tt:node name="TYPE_CSV" type="C" length="1" />
<tt:node name="TYPE_XLS" type="C" length="1" />
<tt:node name="TYPE_PDF" type="C" length="1" />
<tt:node name="IS_NEW" type="C" length="1" />
</tt:type>
<tt:root name="ROOT2" type="pp:REPORT" />
    <QueryResponse>
    <tt:loop ref="ROOT2" name="line">
      <QueryResponseRow>
        <CompanyID>
          <tt:value ref="$line.COMPANY_ID" />
        </CompanyID>
        <JobID>
          <tt:value ref="$line.JOB_ID" />
        </JobID>
        <ExportTypes>
          <tt:loop>
            <ExportType>
               I don't know what to do here (see item 3, below)
            </ExportType>
          </tt:loop>
        </ExportTypes>
        <IsNew>
          <tt:value ref="$line.IS_NEW"
          map="val(' ') = xml('false'), val('X') = xml('true')" />
        </IsNew>
      </QueryResponseRow>
      </tt:loop>
    </QueryResponse>
    </tt:loop>
1. In a DTD, an element can be designated as occurring zero or one
time, zero or more times, or one or more times. How do I write the
simple transformation to accommodate these possibilities?
2. In trying to accommodate the "zero or more times" case, I am trying
to use the <tt:loop> instruction. It occurs several layers deep in the
XML hierarchy, but at the top level of the ABAP table. The internal
table has a structure defined in the ABAP program, not in the data
dictionary. In the simple transformation, I used <tt:type> and
<tt:node> to define the structure of the internal table and then
tried to use <tt:loop ref="ROOT2" name="line"> around the subtree that
can occur zero or more times. But every variation I try seems to get
different errors. Can anyone supply a working example of this?
3. Among the fields in the internal table, I've defined three
one-character fields named TYPE_CSV, TYPE_XLS, and TYPE_PDF. In the
XML file, I expect zero to three elements of the form
<ExportType exporttype='csv' />
<ExportType exporttype='xls' />
<ExportType exporttype='pdf' />
I want to set field TYPE_CSV = 'X' if I find an ExportType element
with its exporttype attribute set to 'csv'. I want to set field
TYPE_XLS = 'X' if I find an ExportType element with its exporttype
attribute set to 'xls'. I want to set field TYPE_PDF = 'X' if I find
an ExportType element with its exporttype attribute set to 'pdf'. How
can I do that?
4. For an element that has a value like
<ErrorCode>123</ErrorCode>
in the simple transformation, the sequence
<ErrorCode> <tt:value ref="ROOT1.CODE" /> </ErrorCode>
seems to work just fine.
I have other situations where the XML reads
<IsNew value='true' />
I wanted to write
<IsNew>
        <tt:value ref="$line.IS_NEW"
        map="val(' ') = xml('false'), val('X') = xml('true')" />
       </IsNew>
but I'm afraid that the <tt:value> fails to deal with the fact that in
the XML file the value is being passed as the value of an attribute
(named "value"), rather than the value of the element itself. How do
you handle this?

Try this code below:
data l_xml_table2 type table of xml_line with header line.
W_filename - This is a Path.
if w_filename(02) = '
    open dataset w_filename for output in binary mode.
    if sy-subrc = 0.
      l_xml_table2[] = l_xml_table[].
      loop at l_xml_table2.
        transfer l_xml_table2 to w_filename.
      endloop.
    endif.
    close dataset w_filename.
else.
    call method cl_gui_frontend_services=>gui_download
      exporting
        bin_filesize = l_xml_size
        filename     = w_filename
        filetype     = 'BIN'
      changing
        data_tab     = l_xml_table
      exceptions
        others       = 24.
    if sy-subrc <> 0.
      message id sy-msgid type sy-msgty number sy-msgno
                 with sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

Convert XML file into ABAP Query

Hi All,
Can we capture a XML file generated from a Non-SAP system in SAP system and convert into ABAP Query to retreive Data from DB and post it back as a XML query to the same Non-SAP system using a Middleware. Can this process be done in cache memory level itself instead of saving in DB.
If it is possible pls do tell the procedure and steps to be followed.
Suggestion and Help will be much Appreciated
Thanks & Regds.

Receive CSV attachment via Mail Adapter and process into ABAP proxy

Hi,
I have the following scenario:
1. Receive e-mail with CSV attachment
2. Process through Mail adapter (KeepAttachments = Yes in order to retain the CSV attachment)
3. Receive into ABAP proxy (with CSV attachment)
The next step is to read the attachment in the ABAP proxy and process the CSV attachment data into CRM.
The CSV attachment contains the data I wish to process - the body of the e-mail will not contain this information.
The problem I have is reading the attachment data in the proxy - not sure of the methods/class to call - anyone got any ideas ?
Another question is this the best way to do this and process the CSV attachment data ?
I know I could use the PayloadSwapBean to switch the payload to the attachment but then I am stumped with how the attachment is processed through PI 7.1 - how do you transform the CSV format payload into XML so PI will be able to process it through mapping.
Either option is viable - an answer to either question would be great.
1. How do you read the attachment data in an inbound ABAP proxy ?
2. How do you transform the CSV attachment data after the PayloadSwapBean from CSV to XML ?
Kind regards
Colin.

Hi Colin
As you are not interested in processing the body of email. Swap the payload to the attachment using the PayloadSwapBean
Change the content from CSV to XML using MessageTransformBean. Now pass this information to Proxy. You dont need to deal with attachments in proxy.
It is not possible to read attachment in server proxy because the class and interface you create will not have data type which can refer to an attachment processing interface in ABAP.
Thanks

How to read Filter selection variable values into ABAP code

HI IP Gurus,
Requierement: In my filter characterstics, i have assigned variables, which use will enter when running th e planning sequence.
so variable values entered by user , i would like to get those values into ABAP code and pass them to some function module.
SO please give me step by step detail how to achive this.
MY understanding use the below method . but not sure how to proceed.Please let me know abap code to get values.
GET_TAB_PARAM_DATA_SEL and GET_PARAM_DATA_SEL.
Please help me.
Thanks in advance.Will Assign points
Sania

Hi Srinivas,
So In RSPLF1 , in paramters tab, Do i have create structure(str1) and then create component Data selection (Dtsel1) under str1(what setting i have to do here, where should i enter variable value and do i need to give info object name and how do it in code.i tried to following example, not able to get any values in tab_sel .
It will be great, if you could explain in detail.
other thing i found out is in Initialization method i can read i_t_data_charsel table values , where it contains filter slected values.but could not pass these values to execute method
Is there is any way that i can pass values from init method to execute method.
A tabular structured parameter with name "MY_TABSTRUC" is defined for the function type. "MY_TABSTRUC" consists of the two parameter components "MY_ELEM" and "MY_DATASEL". You access the parameter values as follows:
DATA: TAB_PARAM_STRUC TYPE RSPLFA_T_PARAM_STRUC,
       REF_PARAM_STRUC    TYPE REF TO IF_RSPLFA_PARAM_STRUC,
      REF_PARAM_ELEM     TYPE REF TO IF_RSPLFA_PARAM_ELEM,
      REF_PARAM_DATASEL TYPE REF TO IF_RSPLFA_PARAM_DATESEL,
       L_VAL(20)          TYPE C,
       TAB_SEL            TYPE RSPLF_T_CHARSEL.
get table of parameter MY_TABSTRUC:
TAB_PARAM_STRUC = I_R_PARAM_SET->GET_TAB_PARAM_STRUC( 'MY_TABSTRUC' ).
process all lines:
LOOP AT TAB_PARAM_STRUC into REF_PARAM_STRUC.
get component MY_ELEM:
    REF_PARAM_ELEM = REF_PARAM_STRUC->GET_COMP_ELEM( 'MY_ELEM' ).
get internal value of MY_ELEM:
    REF_PARAM_ELEM->GET_VALUE( IMPORTING E_VALUE = L_VAL ).
get component MY_DATASEL:
    REF_PARAM_DATASEL = REF_PARAM_STRUC->GET_COMP_DATA_SEL( 'MY_DATASEL' ).
get data selection table of MY_DATASEL:
    TAB_SEL = REF_PARAM_DATASEL->GET_T_SEL( ).
ENDLOOP.

Vim embedded into abap editor

Is there any way to embed VIM into abap editor on windows.
I know that it is possible to embed Vim in linux version of SAP gui.
Any one has ideas?

Is there any way to embed VIM into abap editor on windows.
Haven't heard about this one, but since the idea sounded pretty good to me I tried to find any evidence in the web. However, at least I noticed that the Eclipse-VIM integration seems to be working now. So thanks for the posting and getting things rolling...
I know that it is possible to embed Vim in linux version of SAP gui.
Not sure what you mean by linux version of SAPgui. Basically the only SAPgui version that exists for Linux is the Java GUI (assuming that we're not talking about trying to run the Windows SAPgui in Wine environment). I personally doubt that such a thing exists, but if you know any details, please share your knowledge or links...
VIM has a socket interface which allows in theory IDE's to attach (:help netbeans), but haven't heard that anything exists in the SAP world to utilize this. Maybe there's other ways, so let us hear what you know...
Thanks, harald

What am I doing wrong or what do I need to do? I'm lost!
Thank you for your help!
Johannes.

Thank you Durairaj, as a matter of fact my program is based on your post (one that you pointed me to). For whatever reason I'm not having luck figuring it out (may be just a bit of work pressure) could you please hlep me a bit more by pointing me to where in my program code/xslt I'm going wrong? I somehow feel that it could be my table structure or xslt.
I would really appreciate it!
Thanks again,

Integrating Web Dynpro for ABAP into ABAP Workflow

We have a requirement to create a User Interface via Web Dynpro for ABAP, and use that information to start off a workflow, transferring the data from the Web Dynpro application into the container of the Workflow.
Also later in the workflow, we would like an approval step to invoke a Web Dynpro that displayes the data, and an approve/reject button to be pressed that feeds that data back to the Workflow.
Has anybody done this, or does anybody know how to do this? We do not have the possibilities to use CAF in this project yet.
Kind Regards,
Tony.

Hi,
This is of course possible. Starting the workflow with Web Dynpro or from classic ABAP dynpro doesn't really differ. Just build your web dynpro as you would build a transaction, and from the submitting/execution phase, you just launch the workflow. Launching the workflow can be done with couple of different techniques (=function modules) and it has been discussed many times here.
Also the approval part shouldn't cause any problems. Just build an application which takes as a parameter for example the work item ID (or any other relevant parameter that you can imagine, which you can use to retrieve the needed data that you want to display). Then from the web dynpro application you can call for example a function module, which can complete the work item. Or another option is that you will raise an event (again with a function module), which your approval task is waiting for.
Once again, it isn't really that different from classic dynpro (or any other technique) - the same approaches can be utilized.

Karri

Integrating External Operating System Commands into ABAP program.

Hi folks,
using the transaction code sm69 it is possible to create an SAP command that's executing an operating system command.
Is it possible to integrate such an SAP command into our ABAP programs ?
How would we do so ?
Regards
Thomas

Hello Thomas,
We have an easier way of achieving this without declaring a command in SM69.
Try the below piece of code:
DATA: command LIKE rs37a-line.
DATA: BEGIN OF tabl OCCURS 0,
          line(2000),
      END OF tabl.
command = 'ls -l'.
CALL 'SYSTEM' ID 'COMMAND' FIELD command
              ID 'TAB'     FIELD tabl-*sys*.
Replace the string in the variable 'comand' with any UNIX command.
Regards
Sabu
