Equivalent Statement in ECC6.0
Hi,
I want the equivalent statement of the following in ECC6.0.
SELECT MCOMP SUM( PSMNG ) INTO CORRESPONDING FIELDS OF
ITAB_NEW FROM (ITAB_SEL)
GROUP BY MCOMP.
ENDSELECT.
This statement is giving error in the new Version. Error is " Table ITAB_SEL " must have a character line type(data type C,N, D,T, or String)
Useful answer will be rewarded with points.
okay, i'm guessing ITAB_SEL is an internal table and it contains some numeric fields
what you need to do, is to declare itab_sel with all character fields
depending on the way you are getting data into ITAB_SEL (since some FMs need a particular datatype), you may need to make another internal table with all character fields and use the MOVE-CORRESPONDING statement
then pass this NEW_ITAB_SEL to your select statement

Equivalent statements in ECC6.0
Hi Experts,
We are in process of upgrading our system from 4.6c to ecc6.0 .While upgrading i encountered an issue
where in i came across a statement ."RECORD_TAB[] = T_OUTPUT[].Record_tab and t_output are of different structures.
data : begin of t_output occurs 0 ,
vbeln like vbrk-vbeln,
fkart like vbrk-fkart,
posnr like vbap-posnr,
erdat like vbrk-erdat,
netwr like vbrp-netwr,
mcod1 like kna1-mcod1,
vbeln_c like vbap-vbeln,
ktext like vbak-ktext,
ename1 like pa0001-ename,
arktx like vbrp-arktx,
ename2 like pa0001-ename,
kunnr like kna1-kunnr,
pernr_zi like vbpa-pernr,
pernr_zj like vbpa-pernr,
end of t_output.
and Record_tab is of type SEAHLPRES(Search help result Structure).The above statement runs without errors in 4.6c version but throwing an error when executed in ECC6.0(Error is record_tab and t
output are mutually not convertible .In unicode programsboth must have the same structurelayout as toutput,independent of the length of unicode character)
.Please suggest on how can i replace the above statement in ECC6.0.
Regards,
Lakshman.Hi Lakshman,
try to use this statement may be some corrections are required.
DATA: lv_netwr(21) type c.
LOOP AT t_output.
WRITE t_output-netwr TO lv_netwr.
CONCATENATE t_output-vbeln t_output-fkart t_output-posnr t_output-erdat lv_netwr t_output-mcod1 t_output-vbeln_c t_output-ktext t_output-ename1 t_output-arktx t_output-ename2 t_output-kunnr t_output-pernr_zi t_output-pernr_zj INTO wa_seahlpres-string.
APPEND wa_seahlpres TO RECORD_TAB.

Is there an equivalent statement in Java for this PL/SQL stmt?
Hi,
I want to know if there is an equivalent statement
in java for this PL/SQL statement:
IF strTok IN('COM-1','COM-2','COM-3') Then
/* Do Something */
End If;
I tried using : // This is giving me errors..
if (strTok.equals(("COM-1") || ("COM-2") || ("COM-3") ) )
/* Do Something */
The above Java code is giving me errors.
Any Help to reduce the number of steps for comparison
is appreciated.
thanks in adv
SharathSomething like
if (strTok.equals("COM-1") ||
strTok.equals("COM-2") ||
strTok.equals("COM-3") )Justin

HI,
How to use the DELETE statement in ECC6.0.
when i am using this statement , it is going to short dump.
Delete itab from wtab.
pls let me know
i am getting the error ,
convert the charater to numerics, only numerics are supported in at the argument position , bcos it is a unicode program.
let me know pls .
regards,hi,
chk the syntax:
DELETE - itab_lines
Syntax
... itab [FROM idx1] [TO idx2] [WHERE log_exp]... .
Extras:
1. ... FROM idx1
2. ... TO idx2
3. ... WHERE log_exp
Effect
To delete several lines at once, you have to specify at least one of the additions FROM, TO, or WHERE. You can only use the additions FROM and TO with standard tables and sorted tables.
If you specify several of the additions, the rows are deleted that result from the intersection of the individual additions.
Addition 1
... FROM idx1
Effect
If you specify FROM, all the table rows from the table index idx1 onwards are included. idx1 must be a data object with type i. If the value of idx1 is less than or equal to 0, a runtime error occurs. If the value is greater than the number of table rows, no rows are deleted.
Addition 2
... TO idx2
Effect
If you specify TO, only the table rows up to table index idx2 are included. idx2 must be a data object with type i. If the values of idx2 is less than or equal to 0, a runtime error occurs. If the value is greater than the number of table rows, it is set to the number of rows. If idx2 is less than idx1, no rows are deleted.
Addition 3
... WHERE log_exp
Effect
You can specify any logical expression log_exp after WHERE, for which the first operand of each individual comparison is a component of the internal table. This enables all logical expression with the exception of IS ASSIGNED, ISREQUESTED, and IS SUPPLIED. The dynamic specification of components using character-type data objects in parentheses is not supported here. All rows for which the logical expression is true are deleted.
hope this helps u,

SWWRUNMETH Equivalent table in ECC6.0
Hi,
We are upgrading from 4.6B to ECC6.0 and noticed that the SWWRUNMETH table is obsolete in ECC6.0. Could you please tell me the equivalent tabe in ECC6.0?.
Thanks in advance.

Hi all,
I am working on ECC6.0 , but when i use Read statement it gives me erro that it is obsolute in ECC6.0.
So please suggest a way to proceed.
Regards,
NileshHi Nilesh,
READ statement is NOT Obsolete in ECC 6.0. It is very much in use. I think the syntax that you used might not be correct. Kindly verify with below syntax..
READ TABLE itab INTO ls_itab WITH KEY (Key fields) BINARY SEARCH.
WITH KEY
can be used or
WITH INDEX
can also be used..

How to define perform with table statement in ECC6.0
Hi all,
I am working on ECC6.0 version. I m using a perform to populate an internal table like this:-
PERFORM explode TABLES li_zmpsdtl
USING gs_matnr.
& its forms is defined as: -
FORM treat_one_item TABLES li_zmpsdtl STRUCTURE zmpsdtl
USING gs_matnr TYPE matnr.
doing some action..............
endform.
While performing SLIN it shows an error message :-
" The current ABAP command is obsolete.
Within classes and interfaces, you can only use "TYPE" to refer to ABAP Dictionary types (not "LIKE" or "STRUCTURE"). "
If i use type in place of STRUCTURE then it is ok, but zmpsdtl should be defined as table type. :-
FORM treat_one_item TABLES li_zmpsdtl type zmpsdtl
USING gs_matnr TYPE matnr.
doing some action..............
endform.
is there any other option to do the same thing. i dont want to create any teable type.
Thanx in advance,
SachinYou have to use a global structure instead of a ddic structure after the STRUCTURE statement:
<b>DATA: gs_zmpsdtl TYPE zmpsdtl.</b>
FORM treat_one_item TABLES li_zmpsdtl STRUCTURE <b>gs_zmpsdt</b>
USING gs_matnr TYPE matnr.

SQL Server uniqueidentifier cast to binary...what is equivalent in Oracle?
Hi,
I am having trouble understanding equivalent data types in my conversion from SQL Server to Oracle.
Let's say I have this statement in SQL Server, where the string being "passed in" is a uniqueidentifier:
select cast(substring('EFDA8997-63AA-4F33-96CF-29BFC2CE252E',8,1) as binary(1));
The tool I've used to convert this to Oracle says the equivalent statement to this is (where the string being "passed in" is a char:
select cast((substr('EFDA8997-63AA-4F33-96CF-29BFC2CE252E',8,1)) as raw(1)) from dual;
However, I get different results when testing these two statements:
SQL Server: 0x37
Oracle: 07
What is the correct what to convert this statement to Oracle?
Thank you!
MimiI should add that this an n-tier application, where data is passed across multiple tiers, so the client UI has no connection to the database.
I'm assuming this means that select..for update is not suitable, as that would require a connection to the database to be held open for a specific user in the middle-tier. Not suitable for a scalable, n-tier scenario. -
Put prepended "WITH" into Select statement possible?
Assume I have a SQL statement like:
with t1 as (select ......),
t2 as (select ......)
Select .... From t1, t2 Where ....;
Can I merge somehow the prepended "with" term into the actual select statement?
As far as I remember there is an equivalent statement syntax like:
Select .... from t1 as (select ....), t2 as (select ....) where ....;
but this does not work.
PeterIt will be like
Select ....
From ( select .. From ...) t1
,( select .. From ...) t2
WHERE ...

Hi --- bdc recording in ecc6 version
hi all
while recording in shdb transaction in ECC6 version, i see different kind of recording in the end as compare to recording in 4.6c version, i mean i do not see perform statements in that.
in ecc6, there are 6 colomns but there is no perform statements.
therefore my querry is how to pick up perform statements in ECC6 version after recording.

Not that you asked, but as you proabably know, analytic functions are much better at doing this kind of thing.
You may be amazed (as I continually am) by how simple and efficient these queries can be.
For example:
WITH got_grp AS
SELECT proj_id, proj_start, proj_end
, proj_end - SUM (proj_end - proj_start) OVER (ORDER BY proj_start) AS grp
FROM v
SELECT ROW_NUMBER () OVER (ORDER BY grp) AS proj_grp
, MIN (proj_start) AS proj_start
, MAX (proj_end) AS proj_end
FROM got_grp
GROUP BY grp
ORDER BY proj_start
;Produces the results you want:
PROJ_GRP PROJ_START PROJ_END
1 01-Jan-2005 05-Jan-2005
2 06-Jan-2005 07-Jan-2005
3 16-Jan-2005 20-Jan-2005
4 21-Jan-2005 22-Jan-2005
5 26-Jan-2005 30-Jan-2005This is problem is an example of Neighbor-Defined Groups . You want to GROUP BY something that has 5 distinct values, to get the 5 rows above, but there's nothing in the table itself that tells you to which group each row belongs. The groups are not defined by any column in hte table, but by relationships between rows. In this case, a row is in the same group as its neighbor (the row immediatly before or after it when sorted by proj_start or proj_end) if proj_end of the earlier row is the same as proj_start of the later row. That is, there is nothing about 03-Jan-2005 that says the row with proj_id=2 is in the first group, or even that it is in the same group with its neighbor, the row with proj_id=3. Only the relation between those rows, the fact that the earlier row has end_date=03-Jan-2005 and the later row has start_date=03-Jan-2003, that says these neighbors belong to the same group.
You're figuring out when a new group starts, and then counting how many groups have already started to see to which group each row belongs. That's a prefectly natural procedural way of approaching the problem. But SQL is not a procedural language, and sometimes another approach is much more efficient. In this case, as in many others, a Constant Difference defines the groups. The difference between proj_end (or proj_start, it doesn't matter in this case) and the total duratiojn of the rows up to that date determines a group. The actual value of that difference means nothing to you or anybody else, so I used ROW_NUMBER in the query above to map those distinct values into consecutive integers 1, 2, 3, ... which are a much simpler way to identify the groups.
Note that the query above only requires one pass through the table, and only requires one sub-query. It does not need a WITH clause; you could easily make got_grp an in-line view.
If you used analytic functions (LEAD or LAG) to compute flag, and then to compute proj_grp (COUNT or SUM), you would need two sub-queries, one for each analytic function, but you would still only need one pass through the table. Also, those sub-queries could be in-line views; yiou would not need to use a WITH clause. -
Equivalent to Application.EnableEvents = False in VBA
With Visual Basic 2013 is there an equivalent statement to the VBA "Application.EnableEvents = True/False"? I am loading a saved information file into a form and I want to temporarily turn off event checking (so the changes in the
many text boxes don't trigger the event handlers for each of them) until the form is loaded, then turn it back on. I looked at "AddHandler" and "RemoveHandler" but these require doing it for each text box individually. (ugh!)Another example

How do I convert an HTML5 Canvas arc() to JavaFX Canvas arc()?
I wish to convert a statement from JavaScript used in an HTML5 Canvas such as:
ctx.arc(x, y, (rad+5)*factor, 0, Math.PI*2, true);
to the equivalent statement in JavaFX.
What would it look like?
For reference, in HTML5 Canvas the arc() method is defined as:
x
The x-coordinate of the center of the circle
Play it »
y
The y-coordinate of the center of the circle
Play it »
r
The radius of the circle
Play it »
sAngle
The starting angle, in radians (0 is at the 3 o'clock position of the arc's circle)
Play it »
eAngle
The ending angle, in radians
Play it »
counterclockwise
Optional. Specifies whether the drawing should be counterclockwise or clockwise. False=clockwise, true=counter-clockwise
but in JavaFX it is defined as:
public void arc(double centerX, double centerY, double radiusX, double radiusY, double startAngle, double length)
Adds path elements to the current path to make an arc that uses Euclidean degrees. This Euclidean orientation sweeps from East to North, then West, then South, then back to East.
Parameters:
centerX - the center x position of the arc.
centerY - the center y position of the arc.
radiusX - the x radius of the arc.
radiusY - the y radius of the arc.
startAngle - the starting angle of the arc in the range 0-360.0
length - the length of the baseline of the arc.
Could someone please show me what the JavaFX arc() statement would look like and explain how to convert between these two?
Thanks.No conversion possible. Are you on a responsive project perhaps? Then
output is only HTML, mobile devices do not support Flash. -
With header line & with out header line ?
what is difference between with header line & without header line ?
When you create an internal table object you can also declare a header line with the same name. You can use the header line as a work area when you process the internal table. The ABAP statements that you use with internal tables have short forms that you can use if your internal table has a header line. These statements automatically assume the header line as an implicit work area. The following table shows the statements that you must use for internal tables without a header line, and the equivalent statements that you can use for internal tables with a header line:
Operations without header line
Operations with header line
Operations for all Table Types
INSERT <wa> INTO TABLE <itab>.
INSERT TABLE ITAB.
COLLECT <wa> INTO <itab>.
COLLECT <itab>.
READ TABLE <itab> ... INTO <wa>.
READ TABLE <itab> ...
MODIFY TABLE <itab> FROM <wa> ...
MODIFY TABLE <itab> ...
MODIFY <itab> FROM <wa> ...WHERE ...
MODIFY <itab> ... WHERE ...
DELETE TABLE <itab> FROM <wa>.
DELETE TABLE <itab>.
LOOP AT ITAB INTO <wa> ...
LOOP AT ITAB ...
Operations for Index Tables
APPEND <wa> TO <itab>.
APPEND <itab>.
INSERT <wa> INTO <itab> ...
INSERT <itab> ...
MODIFY <itab> FROM <wa> ...
MODIFY <itab> ...
Using the header line as a work area means that you can use shorter statements; however, they are not necessarily easier to understand, since you cannot immediately recognize the origin and target of the assignment. Furthermore, the fact that the table and its header line have the same name can cause confusion in operations with entire internal tables. To avoid confusion, you should use internal tables with differently-named work areas.
The following example shows two programs with the same function. One uses a header line, the other does not.
With header line:
TYPES: BEGIN OF LINE,
COL1 TYPE I,
COL2 TYPE I,
END OF LINE.
DATA ITAB TYPE HASHED TABLE OF LINE WITH UNIQUE KEY COL1
WITH HEADER LINE.
DO 4 TIMES.
ITAB-COL1 = SY-INDEX.
ITAB-COL2 = SY-INDEX ** 2.
INSERT TABLE ITAB.
ENDDO.
ITAB-COL1 = 2.
READ TABLE ITAB FROM ITAB.
ITAB-COL2 = 100.
MODIFY TABLE ITAB.
ITAB-COL1 = 4.
DELETE TABLE ITAB.
LOOP AT ITAB.
WRITE: / ITAB-COL1, ITAB-COL2.
ENDLOOP.
Without header line:
TYPES: BEGIN OF LINE,
COL1 TYPE I,
COL2 TYPE I,
END OF LINE.
DATA: ITAB TYPE HASHED TABLE OF LINE WITH UNIQUE KEY COL1,
WA LIKE LINE OF ITAB.
DO 4 TIMES.
WA-COL1 = SY-INDEX.
WA-COL2 = SY-INDEX ** 2.
INSERT WA INTO TABLE ITAB.
ENDDO.
WA-COL1 = 2.
READ TABLE ITAB FROM WA INTO WA.
WA-COL2 = 100.
MODIFY TABLE ITAB FROM WA.
WA-COL1 = 4.
DELETE TABLE ITAB FROM WA.
LOOP AT ITAB INTO WA.
WRITE: / WA-COL1, WA-COL2.
ENDLOOP.
The list, in both cases, appears as follows:
1 1
2 100
3 9
The statements in the program that does not use a header line are easier to understand. As a further measure, you could have a further work area just to specify the key of the internal table, but to which no other values from the table are assigned.
Internal table with header line
you can use anywhere except obkect oriented concept.
Internal table without header line :
You should use in Object oriented concept..
Always try to use without header line,performance point of view it is best..
Example :
Without header line.
Structure
types : begin of ty_itab ,
matnr type mara-matnr,
end of ty_itab.
Internal table
data i_itab type standard table of ty_itab .
Work area
data wa_itab like line of i_itab
With header line
data : begin of i_itab occurs 0,
matnr like mara-matnr,
end of i_itab
itab with header lines are obsolete, anyway it will work but not recommended. instead use work area or more effiecient is field symbols. so donot use itab with header line.
i will explain use of itab w/o header line.
Data: itab1 type standard table of mara with header line occurs 0,
itab2 type standard table of mara,
wa_itab2 type mara.
loop at itab1.
"This will work fine.
endloop.
loop at itab2.
"This will give erro that itabd does not hav workarea
endloop.
"so write
loop at itab2 into wa_itab2.
"This will work
endloop.
<b>The difference between
whih header line and with out heater line of internal table.
ex:-
a) Data : itab like mara occurs 0 with header line.
b) Data: itab like mara occurs 0.
-While adding or retrieving records to / from internal table we have to keep the record temporarily.
-The area where this record is kept is called as work area for the internal table.
-The area must have the same structure as that of internal table. An internal table consists of a body and an optional header line.
-Header line is a implicit work area for the internal table. It depends on how the internal table is declared that the itab will have the header line or not.
a) Data : itab like mara occurs 0 with header line.
table is with header line
b) Data: itab like mara occurs 0.
table is without header line</b>
