How to read a file with value of RAW data type? Please help

Hi Experts,
   I have a file with RAW data like DE864E48833BFFF1B805001CC4EF4BFA
   I am using GUI_UPLOAD.
   But this FM is throwing error.
   I tried by giving FILETYPE as ASC. The output internal table for this FM contains a field of type c size 32.
   Now it is able to read the file but I want to assign this value to a RAW data type variable.
   This it is unable to do. How to convert the char value to RAW data type?
Please help!
Thanks
Gopal

Set type attribute search help in Web UI

Hello,
I've created a set type attribute in the SAP GUI in CRM 2007 which links to value table BUT000. On the product in the SAP GUI, the F4 search help brings up the standard BP search help (COM_PARTNER).
I've assigned the attribute to the web UI, and the field displays correctly, however when I click on the F4 help, the system only shows me a list of BP numbers without even a description description, and not the standard search help. The response to my OSS message is that this is "standard".
Any suggestions as to how to enable the correct search help for this?
Thanks,
Alison

        et_guidlist            = et_guidlist
        et_return              = et_return.
ELSE.
Standard search
    CALL METHOD me->search_standard
      EXPORTING
        it_search_tab          = it_search_tab
        it_multivalues         = lt_multivalues
        iv_number              = iv_number
        iv_item                = iv_item
        iv_archive             = iv_archive
        iv_call_authority_badi = iv_call_authority_badi

        et_guidlist            = et_guidlist
        et_return              = et_return.

You have to fill et_guidlist with the results.

Issue Resolved. For less than 50 records, client side filtering takes over. In that case the search help exit will not come into picture. Issue resolved by avoiding client side rendering.

Can't open RAW or CR2 files anymore, Get message "Wrong type of file" HELP PLEASE

As a photographer I shoot in RAW or CR2 an di have used my photoshop elements to tweak my pictures for hte last year but now my program says "Wrong type of file"...nothing has changed, so why can't I open these any more? Anyone? please help
Thanks
Rob

What camera model and what version of the raw plug-in are you using with Elements?
It is possible the pictures are corrupted and cannot be read. You can try opening them in the Canon DPP software that should have come with your camera and try exporting as a JPG from inside there and see if it also reports a bad file. Or you can post a public download link for one of your files, here, and others can try the files in their Photoshop or Lightroom and see if they work or not.

Dynamic structure of "string" data type. Please help.

ABAPers,
I am calling cl_alv_table_create=>create_dynamic_table method to dynamically create a structure. The input structure definition is as follows:
data: xfc type lvc_s_fcat.
data: ifc type lvc_t_fcat.
* define Fld1
clear xfc.
xfc-fieldname = 'Fld1'.
xfc-datatype = 'string'.
append xfc to ifc.
* define Fld2
clear xfc.
xfc-fieldname = 'Fld2'.
xfc-datatype = 'string'.
append xfc to ifc.
Although the call to create_dynamic_table does not throw any exceptions, it appears Fld1 and Fld2 are not of "string" data type. I don't know of a way to see what type they are. However, they do have a length limit of 10 characters.
After some experimenting, it turns out that the method simply ignores "datatype" value if it doesn't understand it and creates the field with some default data type.
I would appreciate it if someone can show me how to create fields of "string" data type.
Thank you in advance for your help.
Pradeep

That's right, use STRG as the datatype. Please see the example program.
report zrich_0003.
type-pools: slis.
data: new_table type ref to data,
      new_line type ref to data.
data: xfc type lvc_s_fcat,
       ifc type lvc_t_fcat.
field-symbols: <dyn_table> type standard table,
               <dyn_wa>,
               <fs>.
start-of-selection.
clear xfc.
xfc-fieldname = 'Field1' .
xfc-datatype = 'STRG'.
append xfc to ifc .
clear xfc.
xfc-fieldname = 'Field2' .
xfc-datatype = 'STRG'.
append xfc to ifc .
* Create dynamic internal table and assign to FS
call method cl_alv_table_create=>create_dynamic_table
    exporting
      it_fieldcatalog = ifc
    importing
      ep_table        = new_table.
assign new_table->* to <dyn_table>.
* Create dynamic work area and assign to FS
create data new_line like line of <dyn_table>.
assign new_line->* to <dyn_wa>.
assign component 1 of structure <dyn_wa> to <fs>.
<fs> = 'This is string 1'.
assign component 2 of structure <dyn_wa> to <fs>.
<fs> = 'This is string 2'.
append <dyn_wa> to <dyn_table>.
* Write the values of internal table.
loop at <dyn_table> into <dyn_wa>.
    do.
      assign component sy-index of structure <dyn_wa> to <fs>.
      if sy-subrc <> 0.
        exit.
      endif.
      write:/ <fs>.
    enddo.
endloop.

How to debug a RFC function when the user is non-dialog type? Please help!

hi Experts,
I am calling a RFC FM residing in B from R/3 system A.
R/3 A -
Call FM residing in B----
> R/3 B
The user attached to the remote destination is a non-dialog type.
I cannot change the user type of this user.
Therefore how to debug the RFC FM in System A?
Are there any alternatives?
Please help
Thanks
Gopal

in your RFC FM, code an endlees loop.
something like:
data: gv_x type xfeld value 'X'.
do.
if gv_x = space.
exit.
endif.
enddo.
now you can catch the mode in TA SM50, go in it, change gv_x to space and debug what is coming further.

Bleed Size, Trim Size, Type Size? Help!!!

Hello, quick question, I'm normally a web designer but we have a couple of print jobs in.
I've been asked for the following.
Bleed size, (281x216mm) fine
Trim size, (275x210mm) fine
Type size...... (257x172mm) um...
Is this the area in which the type should sit....? If so, that sort of screws up my designs....
Thanks in advance, TD

I would interpret that Type Size dimension as the "safe area" in which all important information should be located, but it would help to know more about the project since the dimension listed is quite a bit smaller than would be generated by subracting the bleed allowance from the trim size (how you normally calculate the safe zone), and would suggest margin settings instead.

PLS-00306: wrong number or types of arguments help!!!

Hi,
I am new to pl/sql programming I am stuck into oracle error for my code. Plz help me with this issue my code is as follow:
CREATE OR REPLACE PROCEDURE raise_salary
(emp_id IN employee.employee_nb%TYPE,
amount IN employee.salary%TYPE,
emp_name OUT employee.employee_name%TYPE)
IS
BEGIN
UPDATE employee SET salary= salary+amount WHERE employee_nb = emp_id;
SELECT employee_name INTO emp_name FROM employee WHERE employee_nb=emp_id;
DBMS_OUTPUT.PUT_LINE('SALARY HAS BEEN UPDATED FOR ' || emp_name);
END;
errror:
Error report:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'RAISE_SALARY'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.
*Action:

There is a problem with emp_name OUT employee.employee_name%TYPE parameter. OUT means WRITE ONLY, IN means READ ONLY. So you can not read from an OUT parameter and you are trying to do that in the line
DBMS_OUTPUT.PUT_LINE('SALARY HAS BEEN UPDATED FOR ' || emp_name);
CREATE OR REPLACE PROCEDURE raise_salary(emp_id   IN employee.employee_nb%TYPE,
                                         amount   IN employee.salary%TYPE,
                                         emp_name OUT employee.employee_name%TYPE) IS
BEGIN
UPDATE employee SET salary = salary + amount WHERE employee_nb = emp_id;
SELECT employee_name
    INTO emp_name
    FROM employee
   WHERE employee_nb = emp_id;
/*** DBMS_OUTPUT.PUT_LINE('SALARY HAS BEEN UPDATED FOR ' || emp_name); ***/
--Problem in in the above line. emp_name IS Declared AS OUT
--So it is WRITE ONLY. You can not read from it within the procedure.
END;What you can do is to declare that parameter as IN OUT like
CREATE OR REPLACE PROCEDURE raise_salary(emp_id   IN employee.employee_nb%TYPE,
                                         amount   IN employee.salary%TYPE,
                                         emp_name IN OUT employee.employee_name%TYPE)but there is some other more elegant and better way to do this without hitting the table twice (one for update and one for selecting the name) using RETURNING clause.
SQL> CREATE OR REPLACE PROCEDURE raise_salary(emp_id   IN emp.empno%TYPE,
2                                           amount   IN emp.sal%TYPE,

7     WHERE empno = emp_id RETURNING ename INTO emp_name;

Problem with file types. Please help

I recently downloaded the entire Sun Java Tutorial and have started to go through it. At the end of the first main trail about inro to OO Programming, there is a question/answer portion. There are a couple of excercies where you are to go through the ClickMe app and change some things around. When you click the 'click me' hyperlink, it would open the source in a new Internet Explorer window. That didn't work well for me as I can't very well edit anything in an Explorer window. So, I decided to change and do an 'open with' and used NotePad. Well, it didn't open it in a very readable format... so I thought 'forget it' I want to get it back to the IE format where I can at least read it easily. So, I've started to dig around and now I can no longer do an 'open with' and if you go into the View, Options, File Types 'JAVA' isn't listed anywhere in there.... BUT if I try to add a new type it says'java_auto_file' is associated with another program. So, then I got into REGEDIT and tried to modify the 'java_auto_file' key to use InterNet Explorer... but now I can't get the thing to even open in IE. HELP? If anyone can do this and see what I'm talking about can you figure out how to get me back to how it was when I pulled off the Tutorial....I'm lost. Thanks

Try Netscape -- it lets you see the source files .java when you click on the link.
Messing with Window's Registry is risky business. Try to find the old working copy and restore/rename it.

ex:- Vbeln length = 10
       b_vbeln type i length 12.
b_vbeln = vbeln.

U will get b_vbeln with 2 '0' or always the value be of 12 length.

InDesign crashing when using type tool - any help?

Hi,
Ive looked for this problem in the threads here but couldnt find the solution, only similar problems.
I use InDesign on OSX and it works fine until I use the type tool - in new or old documents. Then it crashes.
I tried reinstalling the program and uninstalling, also uninstalling the last fonts added to the system to no success.
Any help would be much appreciated.

Hi Steve,
Its CC and it was working perfectly.
I was on OSX Mavericks when I last edited documents.
I've updated the OS to Yosemite a few days ago. Illustrator and Photoshop worked perfectly on Yosemite.
I also installed a few fonts, which worked on Illustrator, if that's of any help.
I've uninstalled all the recent additions and tried using InDesign afterwards, but its still crashing.
I can post the error log I receive.
