Problem with DESCRIBE field-symbol statement?
Hi
I havw written following querry but it's showing error. My doubt is there any resctriction field symbols in DESCRIBE query.
i wrote
describe field <a> type typ length in character mode.
Is that syntax correct?
When you use the Describe statement with the field symbols, it will do the describe on the field which was assigned to it.
Like:
FIELD-SYMBOLS: <fs> TYPE ANY.
DATA: l_char TYPE char10.
l_char = 'TEST'.
ASSIGN l_char TO <fs>.
DATA: l_len TYPE i.
DESCRIBE FIELD <fs> LENGTH l_len IN CHARACTER MODE.
write: / '<fs>:', <fs>.
WRITE: / 'Length', l_len.
Here descirbe gives the property of the L_CHAR because it was assigned to field symbol <FS>.

Problem with slis_t_specialcol_alv Field Symbol Assignment
I have created a dynamic internal table (runtime determined number of columns) to contain data to be displayed in an ALV. Ive also made ensured that the last column of the dynamic itab is of type <b>'slis_t_specialcol_alv'</b> and named <b>CINFO</b> to contain color information for that particular row. In the code below the dynamic itab is pointed to by field symbol <dyn_table> while the work area for it would be <dyn_wa>.
Somewhere down the line I attempt to assign the CINFO component of the current row of the itab to a field symbol called <fs_cinfo> typed as slist_t_specialcol_alv (Same as CINFO).
I used the code:
ASSIGN COMPONENT 'CINFO' OF STRUCTURE <dyn_wa> TO <fs_cinfo>.
This gives me the runtime error:
<i>Type conflict in the ASSIGN statement in the program "ZHRR001_TEMMATRIX".
You attempted to assign a field to a typed field symbol,
but the field does not have the required type. </i>
I am unsure why this happens as both the component CINFO and FS <fs_cinfo> are of type slist_t_specialcol_alv.
For some odd reason though during debugging, I took a look at the <dyn_wa> structure and the component type of CINFO was displayed as C???
Here is the relevant portion of code (creation of dynamic itab and attempting to assign <fs_cinfo>)
FIELD-SYMBOLS: <dyn_table> TYPE STANDARD TABLE,

There is a big problem in the program: you are mixing types used for FM-based ALV (SLIS_...) and ABAP-OO based ALV (LVC_...).
For ABAP-OO based row colouring you have to define your itab like this:
TYPES: ty_s_outtab.
INCLUDE TYPE kna1. " just an example
TYPES: rowcolor(4) TYPE c.
TYPES: END OF ty_s_outtab.
TYPES: ty_t_outtab TYPE STANDARD TABLE of ty_s_outtab
WITH DEFAULT KEY.
In the layout (LVC_S_LAYO) you have to set <b>ls_layout-info_fname = 'ROWCOLOR'</b>.
ROWCOLOR has to be filled according to <b>Cxyz</b> whereas
- x = color
- y = inverse on/off
- z = intensified on/off

Problem with the program symbols in quality
Dear all,
I am facing a problem with the program symbols.
I have added new global fields in development, i have called those definations in text names. It is working fine.
After transporting these program changes in to quality these new global definations are not displaying in quality and varibles are not working.
Please give me some suggestion.
Thanks and advanceHi Chandra,
Please check the following.....
(1)The transport request status in se10 and see if has been successfully imported to QA..
(2)if all the declarations or code have been collected in a Transport and not saved as temporary objects
To confirm the same we have to compare the code in quality and development and see if they are the same
Pls check and revert

Problem with currency field in smart form
hi

120.00
0.00
0.00
0.00
i thought the the problem is with space .so iwanted to condense it but cannot as it is currency field so move into character fields .but the user want out put in currency format like 22,60.20 if i get the value in char variable i get 2260.20 which i dont want .
so pls help me how to condense or shift left and print the currency field on right place.

answers will be rewarded points.hi,
this is a normal problem u can avoid this by moveing these currencu value to a character field then print the char field us ing condece... &var(C)&..
eve if not solve the problem use the TEMPLATE node..

Problem with a field set to refresh after insert at Row level
hello all,
i have a problem with a field (a serial) which is set by a db trigger at insertion. The field "refresh after insert" is properly set in the Entity and everything is refreshed correctly when i insert data via an adf form in a jspx but when i want to insert programmatically nothing is refreshed. I insert data this way :
ViewObject insertVO = findViewObject("myView");
Row newRow = insertVO.createRow();
newRow.setAttribute("mandatoryAttribute1",value1);
newRow.setAttribute("mandatoryAttribute2",value2);
<more init here but not the serial since it will be set by the DB trigger>
insertVO.insertRow(newRow);
but when i want to get back the value with "newRow().getAttribute("TheSerial");" i always get a null back and not the value set by the db trigger.
One way to get the serial is to commit after each insert but i don't want to commit between inserts.
i've tried to unset the refresh after insert and override the createDef() method to setUseReturningClause(false) as it's is advised in chapter 26.5 of the ADF 4GL dev. guide but in this case i have an exception JBO-29000: JBO-26041.
How can i get the value back properly ?
thanks
-regardsThe data for the newly created row doesn't get inserted into the database until the commit is executed, so the insert trigger isn't called.
If you need to get the value without committing, then you should implement the trigger programmatically and drop the trigger from the database. The code below shows how you could do this.
ViewObject insertVO = findViewObject("myView");
Row newRow = insertVO.createRow();
SequenceImpl seq = new SequenceImpl("MY_SEQ", insertVO.getDBTransaction());
Long next = (Long)seq.getData();
newRow.setAttribute("primaryAttribute", new Number(next));
...You will need to replace MY_SEQ and primaryAttribute with the correct values for your example, but this should acheive what you want. -
Problem in using Field Symbols in HIDE statement
Hi All,
I am working in an Upgrade project ( from 4.6B to ECC 5.0 ). In a program I found few warnings on HIDE statement because they have used Field Symbols in HIDE statement.
The warning is " HIDE on a field symbol is dangerous, but the formal parameter "" is not ".
and the piece of code is
SET EXTENDED CHECK OFF.
HIDE: flg_pick_up, <s1>, <s2>, <s3>, <s4>, <s5>, z_feld_ind.
CLEAR flg_pick_up.
SET EXTENDED CHECK ON.
all the field symbols are of type ANY. SO can any one help in removing those warnings.
Please reply me as soon as possible.
With Regards,
Amarnath SinganamalaHi amarnath,
1. Why do u want to remove
the warning ?
2. This warning (and not an error)
is a GENUINE warning,
which the system wants the user to make aware of.
3. By doing some xyz,
even if u may be able to hide the warning,
the warning may be hidden (for display purpose only),
but,
the warning will still be there inside the system.
4. I think u should ignore the warning,
(if there are no other repurcussions).

Regarding problem with assigning field to Field symbols
Hi All,
We are migrating(recreating) the program which was in 4.7 to ECC 6.0.
In 4.7 they are using the below code for assigning the field to fieldsymbol from work area as shown below.
ASSIGN wa_kostl_kstar-wkg001+offset TO <von>
wa_kostl_kstar is a work area and wkg001 is the fourth field and wkg011 is 13th field and it is taking this filed into field symbol <Von>.
In Ecc 6.0 th same code is not being accepted and throwing syntax error.
So they had changed the code in ECC 6.0 to
ASSIGN wa_kostl_kstar-wkg001+(offset) TO <von>
And there was no syntax error and while testing it goes to dump.
I had tested in 4.7 and its working fine taking the value of 13 th field to <von>,and like wise there are some other assign statements after,like this.
So any one please let me know what to do in this case.
Regards,
MADHAVA.Hi,
Hope below example can give you an idea on handling your case:
TYPES: BEGIN OF t_sal_ord,
vbeln TYPE vbeln_va,
posnr TYPE posnr_va,
auart TYPE auart,
vkorg TYPE vkorg,
matnr TYPE matnr,
END OF t_sal_ord.
DATA: wa_mara TYPE mara.
DATA: wa_sal_ord TYPE t_sal_ord.
FIELD-SYMBOLS: <fs_matkl>,
<fs_vkorg>.
ASSIGN COMPONENT 'MATKL' OF STRUCTURE wa_mara TO <fs_matkl>.
IF sy-subrc NE 0.
EXIT.
ENDIF.
ASSIGN COMPONENT 'VKORG' OF STRUCTURE wa_sal_ord TO <fs_vkorg>.
IF sy-subrc NE 0.
EXIT.
ENDIF.

Problem after assigning field-symbol in read statement...
Hello Experts,
I want to use a universal field-symbol in reading my internal tables so
I can avoid declaring multiple work areas. Here is my code:
FIELD-SYMBOLS: <fs_any> type any.
READ TABLE lt_orderadm_h INDEX 1 ASSIGNING <fs_any>.
Now when I try to insert this code:
IF NOT <fs_any>-object_id IS INITIAL.
ENDIF.
It says that <fs_any> has no structure and therefore no component called object_id.
I think that I need to use assign component for this but I don't know the code.
Thank you guys and take care!Hi
DATA : WA_ITORDERADM_H LIKE LINE OF IT_ORDERADM_H.
**Try to assign the work area rather type any**
FIELD-SYMBOLS: <fs_any> type WA_ITORDERADM_H.
READ TABLE lt_orderadm_h INDEX 1 ASSIGNING <fs_any>.
Now when I try to insert this code:
IF NOT <fs_any>-object_id IS INITIAL.
ENDIF.
Check this program
This works for me
Simple program.
TYPES: BEGIN OF NAME,
NEXTNAME(10),
FIRSTNAME(10),
LASTNAME(10),
END OF NAME.
FIELD-SYMBOLS <F> TYPE NAME.
DATA: LINE(30).
LINE = 'JOHN SMITH SHRI'.
ASSIGN LINE TO <F> CASTING.
WRITE: / 'Lastname:', <F>-LASTNAME,
'Firstname:', <F>-FIRSTNAME,
'Nextname :', <F>-NEXTNAME

My problem is AT-END OF STATEMENT IS executing for each and every record of same /B28/S_D1DVOX5.
Please help me from this problemHello,
First of all to know clearly about AT END.
Let's say In IT_DATA fields are F1 F2 F3 /B28/S_D1DVOX5 F5.
then AT END of /B28/S_D1DVOX5 means for each new value of this field at the end it will trigger.
Please ensure thet IT_DATA is sorted by this field and then used Control break.

Problems with explain plan and statement
Hi community,
I have migrated a j2ee application from DB2 to Oracle.
First some facts of our application and database instance:
We are using oracle version 10.2.0.3 and driver version 10.2.0.3. It runs with charset Unicode 3.0 UTF-8.
Our application is using Tomcat as web container and jboss as application server. We are only using prepared statements. So if I talk about statements I always mean prepared statements. Also our application is setting the defaultNChar property to true because every char and varchar field has been created as an nchar and nvarchar.
We have some jsp sites that contains lists with search forms. Everytime I enter a value to the form that returns a filled resultset, the lists are performing great. But everytime I enter a value that returns an empty resultset, the lists are 100 times slower. The jsp sites are running in the tomcat environment and submitting their statements directly to the database. The connections are pooled by dbcp. So what can cause this behaviour??
To anaylze this problem I started logging all statements and filled-in search field values and combinations that are executed by the lists described above. I also developed a standalone helper tool that reads the logged statements, executes them to the database and generates an explain plan for every statement. But now there appears a strange situation. Every statement, that performs really fast within our application, is now executed by the helper tool extremely slow. So I edited some jsp pages within our application to force an explain plan from there (tomcat env). So when I'm executing the same statement I'm getting with the exactly same code two completely different explain plans.
First the statement itself:
select LINVIN.BBASE , INVINNUM , INVINNUMALT , LINVIN.LSUPPLIERNUM , LSUPPLIERNUMEXT , LINVIN.COMPANYCODE , ACCOUNT , INVINTXT , INVINSTS , INVINTYP , INVINDAT , RECEIPTDAT , POSTED , POSTINGDATE , CHECKCOSTCENTER , WORKFLOWIDEXT , INVINREFERENCE , RESPONSIBLEPERS , INVINSUM_V , INVINSUMGROSS_V , VOUCHERNUM , HASPOSITIONS , PROCESSINSTANCEID , FCURISO_V , LSUPPLIER.AADDRLINE1 from LINVIN, LSUPPLIER where LINVIN.BBASE = LSUPPLIER.BBASE and LINVIN.LSUPPLIERNUM = LSUPPLIER.LSUPPLIERNUM and LINVIN.BBASE = ? order by LINVIN.BBASE, INVINDAT DESC
Now the explain plan from our application:
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 101 | 28583 | 55 (0)| 00:00:01 |
| 1 | NESTED LOOPS | | 101 | 28583 | 55 (0)| 00:00:01 |
| 2 | TABLE ACCESS BY INDEX ROWID| LINVIN | 93709 | 12M| 25 (0)| 00:00:01 |
|* 3 | INDEX RANGE SCAN | LINV_INVDAT | 101 | | 1 (0)| 00:00:01 |
| 4 | TABLE ACCESS BY INDEX ROWID| LSUPPLIER | 1 | 148 | 1 (0)| 00:00:01 |
|* 5 | INDEX UNIQUE SCAN | PK_177597 | 1 | | 1 (0)| 00:00:01 |
Predicate Information (identified by operation id):
3 - access("LINVIN"."BBASE"=:1)
filter("LINVIN"."BBASE"=:1)
5 - access("LSUPPLIER"."BBASE"=:1 AND "LINVIN"."LSUPPLIERNUM"="LSUPPLIER"."LSUPPLIERNUM")
Now the one from the standalone tool:
| Id | Operation | Name | Rows | Bytes |TempSpc| Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 93773 | 25M| | 12898 (1)| 00:02:35 |
| 1 | SORT ORDER BY | | 93773 | 25M| 61M| 12898 (1)| 00:02:35 |
|* 2 | HASH JOIN | | 93773 | 25M| 2592K| 7185 (1)| 00:01:27 |
| 3 | TABLE ACCESS BY INDEX ROWID| LSUPPLIER | 16540 | 2390K| | 332 (0)| 00:00:04 |
|* 4 | INDEX RANGE SCAN | LSUPPLIER_HAS_BASE_FK | 16540 | | | 11 (0)| 00:00:01 |
| 5 | TABLE ACCESS BY INDEX ROWID| LINVIN | 93709 | 12M| | 6073 (1)| 00:01:13 |
|* 6 | INDEX RANGE SCAN | LINVOICE_BMDT_FK | 93709 | | | 84 (2)| 00:00:02 |
Predicate Information (identified by operation id):
2 - access("LINVIN"."BBASE"="LSUPPLIER"."BBASE" AND "LINVIN"."LSUPPLIERNUM"="LSUPPLIER"."LSUPPLIERNUM")
4 - access("LSUPPLIER"."BBASE"=:1)
6 - access("LINVIN"."BBASE"=:1)
The size of the tables are: LINVIN - 383.692 Rows, LSUPPLIER - 115.782 Rows
As you can see the one executed from our application is much faster than the one from the helper tool. So why picks oracle a completely different explain plan for the same statement? An why is a hash join much slower than a nested loop? Because If I'm right a nested loop should only be used when the tables are pretty small..
I also tried to play with some parameters:
I set optimizer_index_caching to 100 and optimizer_index_cost_adj to 30. I also changed optimizer_mode to FIRST_ROWS_100.
I would really appreciated, if somebody can help me with this issue, because I'm really getting more and more distressed...
Thanks in advance,
Tobias

Hi again,
Here ist the answer:
The problem, because I got two different explain plans, was that the external tool uses the NLS sesssion parameters coming from the OS which are in my case "de/DE".
Within our application these parameters are changed to "en/US"!! So if I'm calling in my external tool the java function Locale.setDefault(new Locale("en","US")) before connecting to the database the explain plans are finally equal.That might explain why you got two different execution plan, because one plan was obviously able to avoid a SORT ORDER BY operation, whereas the second plan required to run SORT ORDER BY operation, obviously because of the different NLS_SORT settings. An index by default uses the NLS_SORT = 'binary' order whereas ORDER BY obeys the NLS_SORT setting, which probably was set to 'GERMAN' in your "external tool" case. You can check the "NLS_SESSION_PARAMETERS" view to check your current NLS_SORT setting.
For more information regarding this issue, see my blog note I've written about this some time ago:
http://oracle-randolf.blogspot.com/2008/09/getting-first-rows-of-large-sorted.html
Now let me make a guess why you observe the behaviour that it takes so long if your result set is empty:
The plan avoiding the SORT ORDER BY is able to return the first rows of the result set very quickly, but could take quite a while until all rows are processed, since it requires potentially a lot of iterations of the loop until everything has been processed. Your front end probably by default only display the first n rows of the result set and therefore works fine with this execution plan.
Now if the result set is empty, depending on your data, indexes and search criteria, Oracle has to work through all the data using the inefficient NESTED LOOP approach only to find out that no data has been found, and since your application attempts to fetch the first n records, but no records will be found, it has to wait until all data has been processed.
You can try to reproduce this by deliberately fetching all records of a query that returns data and that uses the NESTED LOOP approach... It probably takes as long as in the case when no records are found.
Note that you seem to use bind variables and 10g, therefore you might be interested that due to the "bind variable peeking" functionality you might potentially end up with "unstable" plans depending on the values "peeked" when the statement is parsed.
For more information, see this comprehensive description of the issue:
http://www.pythian.com/blogs/867/stabilize-oracle-10gs-bind-peeking-behaviour-by-cutting-histograms
Note that this changes in 11g with the introduction of the "Adaptive Cursor Sharing".

Randolf

Problem related to field-Symbol?
HI All,
I am writting the below coding, Please tell me whether the Field Symbol will act as a table or not as I want to append a lot of data to field symbol. Please tell me is there any problem in the code.
LOOP AT lt_vepoequi_keys into ls_vepoequi_keys.
READ TABLE lt_vekp ASSIGNING <ls_vekp_str> with key
matnr = ls_vepoequi_keys-matnr.
IF sy-subrc = 0.
<ls_vekp_str>-stoff = ls_vepoequi_keys-stoff.
<ls_vekp_str>-sonum = ls_vepoequi_keys-sonum.
<ls_vekp_str>-lagkl = ls_vepoequi_keys-lagkl.
<ls_vekp_str>-lagkt = ls_vepoequi_keys-lagkt.
endif.
endloop.Hi Abhinav,
you have internal table (say it_employee) with fields name,age,senior_category.
now when you loop this internal table you will need workarea.
loop at it_employee into wa_employee.
if wa_employee-age > 60.
wa_employee-senior_category = 'YES'.
else.
wa_employee-senior_category = 'NO'.
endif.
modify it_employee from wa_employee.
endloop.
now one use of Field-symbols is : when internal table is huge and when you loop with workarea and modify internal table each time, it takes time. So if we use Field-symbols performance would increase.
loop at it_employee assigning into <fs_employee>.
if <fs_employee>-age > 60.
<fs_employee>-senior_category = 'YES'.
else.
<fs_employee>-senior_category = 'NO'.
endif.
endloop.
Now you see in the above code, i have not used modify statement because when i loop internal table, the field symbol points directly to the memory of internal table.
So during loop if i assign any value to the field symbol then it directly changes the internal table value, so there wont be any need to use modify statement.
Hope you are clear with this example....

Hi,
I have a problem with a date-field. Maybe I must describe the problem more detailled, but first I just want to ask you, if you know the following error-message: "21.10.2010 kommt nicht in der Menge der erlaubten Werte vor". I don't know the correct translation but it must be something like this: "21.10.2010 does not occur in the quantity of the permitted values". I don't find the position in the sourcecode of this message. And I know, that this message isn't thrown by a functionblock from SAP. So what is the describtion of this message?Yes I have a date field in my form. Ok I must describe it more detailled. I have an employee searchfield. After select an employee you see a form. After filling the form you click on "Send". It creates a ticket and sends the data to the Backend and jumps back to the employee search field. Untill this point everything works fine. There is no problem with the datefield. Now I want to create the form. I choose an employee and fill the form. But now it comes this message. But not after clicking the "send" button. The message comes after changing some data (e.g. change a radio button). So it looks like a validationproblem, but only at the second creationprocess. Maybe the first date is in some cache? I don't know...

Problem in assigning field symbol to a nested internal table
Hi All,
I have searched the forum but could not find a solution to this problem. I have a requirement where I need to define an internal table within an internal table, so I have used pointer within the outer internal table(itab2) which point to the inner table. However, I am facing problem while assigning the pointer.
data: begin of struct1 occurs 0,
fld3(10) type C,
end of struct1.
data: begin of itab2 occurs 0,
fld1(10) type C,
fld2(10) type C,
p_inner like ref to struct1,
end of itab2.
field-symbols <inner_table> type any.
I want to assign "itab2->p_inner->* " to "<inner_table>".
However, the following statement is Not working:
assign itab2->p_inner->* to <inner_table>.
I want to fill the values within fields fld1, fld2 and fld3 and append it in itab2.
The final table should be like:
ITAB2:
fld1 fld2 fld3
aa bb cc
dd
ee
11 22 33
44
55
I have tried many other ways too but could not suceed, please help.
Thanks,
Vishal.Thanks Matt,
But how do I append the values within this internal table ??
When I am using the following code:
ls_wa-fld3 = 'A'.
ls_wa-t_in-fld1 = 'B'.
ls_wa-t_in-fld2 = 'C'.
ls_wa-t_in-fld1 = 'D'.
ls_wa-t_in-fld2 = 'E'.
append ls_wa to lt_tab.
Its giving an error that:
The data object "LS_WA" does not have a component called "T_IN-FLD1".
I wanted the values to be appended in the following way in lt_tab:
fld3 fld1 fld2
A B C
D E
Please help. -
Problem with Date fields in Search panel
Hi all,
I use TP2 and in my jspx page I have a search panel with two date fields and table where the results is displayed. But there is a problem with these date fields, because when I search dates the results is nothing even I retype the date from table. Also I have other pages where this problem exist with same structure.
Could somebody help me with some advice?
Thanks in advance!Hi Frank,
Thanks for the answer.
I use the standart method to make search panel with drag and drop the data control to the page. The other search panel fileds work fine, only the date fileds are problem. Maybe something in view object doesn't work properly.
Here I post the code from my page.

action="#{PeopleBean.onClearVCBtn}"/>
</td>
</tr>
</table>
</af:showDetailHeader>
</td>
</tr>
</table>
Also I have a result table for the search panel, but I don't believe the problem can be there because it works fine when I search in fields different by inputDate.
Do you have any suggestions?
