Error in assign expression

Trying to copy values between two variables, we have the error message that follows.
Please could you help us?
Thanks a lot,
Giovanni

Hi Giovanni,
do you have xmlns:tns="http://samples.otn.com" at the process level? like:
<process xmlns:tns="http://samples.otn.com" ...
</process>
the document and xpath looks correct, only thing is if tns prefix might be refering to wrong namespace instead of http://samples.otn.com

Please, What's wrong?
Thanking in advance

Hi,
Not quite a PL/SQL XML question but anyway...
Since the member function modifies the object instance, the implicit argument "self" must be declared explicitly as "IN OUT" :
member function movimiento (self in out nocopy almacen, p_num number) return boolean

Error while assigning dates to associative array of date type

Hi All,
I am facing the issue while assigning dates to associative array of date type:
Oracle Version:
SQL> select * from v$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bi
PL/SQL Release 10.2.0.1.0 - Production
CORE    10.2.0.1.0      Production
TNS for Linux: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
Stored procedure i am trying to write is as following
create or replace procedure jp1 (
p_start_date date default trunc(sysdate,'MM')
, p_end_date date default trunc(sysdate)
is
l_no_of_days number;
type t_date_id is table of date
index by pls_integer;
l_date_id_arr t_date_id;
begin
l_no_of_days := p_end_date - p_start_date;
for i in 0
.. l_no_of_days - 1
loop
    l_date_id_arr := p_start_date + i;
    dbms_output.put_line(p_start_date + i);
end loop;
end;
I am getting error at line 14 while compiling this. and the error message is as following:
Errors for PROCEDURE JP1:
LINE/COL ERROR
14/5     PL/SQL: Statement ignored
14/22    PLS-00382: expression is of wrong type
So while investigating this i tried to output the value of (p_start_date + i) using dbms_output.put_line and the output is date itself.
create or replace procedure jp1 (
p_start_date date default trunc(sysdate,'MM')
, p_end_date date default trunc(sysdate)
is
l_no_of_days number;
type t_date_id is table of date
index by pls_integer;
l_date_id_arr t_date_id;
begin
l_no_of_days := p_end_date - p_start_date;
for i in 0 .. l_no_of_days-1
loop
    --l_date_id_arr := p_start_date + i;
    dbms_output.put_line(p_start_date + i);
end loop;
end;
output of the
exec jp1
is as following:
01-DEC-13
02-DEC-13
03-DEC-13
04-DEC-13
05-DEC-13
06-DEC-13
07-DEC-13
08-DEC-13
09-DEC-13
10-DEC-13
11-DEC-13
12-DEC-13
13-DEC-13
14-DEC-13
15-DEC-13
16-DEC-13
17-DEC-13
18-DEC-13
I see the output as date itself. so why it is throwing error while assigning the same to associative array of date type.
I tried to google also for the same but to no avail.
Any help in this regard is appreciated or any pointer some other thread on internet or in this forum.
Thanks in advance

Read about associative arrays :
create or replace procedure jp1 (
p_start_date date default trunc(sysdate,'MM')
, p_end_date date default trunc(sysdate)
) is
l_no_of_days number;
type t_date_id is table of date
index by pls_integer;
l_date_id_arr t_date_id;
begin
l_no_of_days := p_end_date - p_start_date;
for i in 0..l_no_of_days - 1
loop
    l_date_id_arr(i) := p_start_date + i;
    dbms_output.put_line(p_start_date + i);
end loop;
end;

ORAMED-01002:[Metadata error in assign operation]

Im using the Oracle Mediator component to assign an expression to a property. The assign expression uses the dvm:lookupValue() function to assign the outcome of the function to the property. When I invoke a message from e.g. SoapUI or the em testfeature it all works perfect. But when I use a testsuite with an initiate message that is similar to the request from SoapUI, the message fails with the following error:
Non Recoverable System Fault:
ORAMED-01002:[Metadata error in assign operation]Metadata Error occurred while assigning to target "$out.property.jca.db.XADataSourceName" using invalid expression "dvm:lookupValue("oramds:/apps/dvm/RegioCode.dvm","RegioCode",$in.request/sadr:GetHoofdaanvragerAdressenRequest/ns6:PersoonKey/ns5:RegioCode,"Datasource","jdbc/DoNotUse")".Possible Fix:Fix the expression. Cause:internal xpath error
Invoke via SoapUI results in the following instance message fragment:

Error while Assigning database level role (db_datareader) to SQL login (Domain Account)

Team,
I got an error while creating a User for Domain Account. Below is the screen shot of the error (error : 15401)
Database instance is on SQL 2000 SP3. ( I know it is out of support, But the customer is relutanct to upgrade)
On Google search, i found below article which is best matching for this error
http://support.microsoft.com/kb/324321
I have follows each step of troubleshooting. But still the issue persists.
Step 1. The login does not exist == The login is very much exist in the domain as i am able to add the same domain id to other database instances
Step 2. Duplicate security identifiers == i have used this query to find duplicate SID
/* SELECT name FROM syslogins WHERE sid = SUSER_SID ('YourDomain\YourLogin') */
But there was only one row returned with create date of today's.
Error while Assigning database level role (db_datareader) to SQL login (Domain Account)
Step 3. Authentication failure == Domain is available. User is able to login on other servers via RDP connection.
Step 4. Case sensitivity == Database collation is set to Case insensitivity. (CI)
Other two 5. Local Accounts & 6. Name resolution == is not applicable to me.
I tried other ways also.
A. Creating login and providing permission in one go only = User account is not created
B. Instead of GUI, use query to create login and provide required permission = Same error.
Does anybody has faced any such situation

Error - ATTRIBUTE_IDOC_METADATA - EDI: Error while assigning IDoc number

Hi,
I'm attempting to create a simple interface which converts cutomer data from a flat file and loads it into a SAP enterprise system as an DEBMAS06 IDoc type. I am getting the error message Error - ATTRIBUTE_IDOC_METADATA - EDI: Error while assigning IDoc number in the XI message monitor.
Has anyone come accross this error before and if so, what is the resolution???
Thanks, in advance,
Pete

Hi Peter,
did you fixed it?
How did you?

Error while assigning Decimal Attribute to PA

Hi,
I am receiving an error while assigning a decimal attribute to the planning area. I am attaching the screen shot below . Can anybody shade some light on this error, what could be the reason ?
Thanks in advance.
Regards,
Chandan

One cannot have a decimal attribute as the 'attribute' in planning. A decimal attribute can always be marked as a key figure.
For eg: Price. It cant be a attribute of planning area (like Plant, product).

Hi Jayakrishnan,
thanks a lot for your answer.
SM59 is working finde. In IDX1 I got the the correct RFC destination entered and a double click works fine also.
The other way around R3 -> XI -> mq series is working fine. Here we are trying mq -> XI -> R3 and it stops sending from XI to R/3.
How to check the IDOC type?

Error when assigning SID while uploading text in the info-object of the DSO

Hi
I have a scenario where I need to extract a char 60 field from R/3 in the DSO.
I have created the info-object which is char 60 which has the master data text activated.
In the DSO transformation I have mapped it to the R/3 field.
While activating the data in DSO its giving the error message
'Value '20 per action plan' (hex. '32302070657220616374696F6E20706C616E') of characteristic'
'Error when assigning SID: Action VAL_SID_CONVERT InfoObject ZRMSD '
How to overcome this issue.
Please advise.
Thanks in advance.

Change the InfoObject for this text so that it will allow lowercase letters. To do this, go into Change mode on the InfoObject, go to the General tab, check the Lowercase letters checkbox and activate the InfoObject. After this has been activated, you can then restart your process and this SID violation error should no longer be thrown for this.
If you don't want to do this, then you can use the TOUPPER formula in the Characteristic Routine, in the Transformation, to change the value of this field contents to uppercase. This can also be done by using an ABAP routine like this:
TRANSLATE column TO UPPER CASE.

Error while assignment of Paying Co Code in FBZP

HI friends,
I am getting the following error while assigning Paying Co Code in FBZP -
Company code 7144 is not permitted as the paying company code
Message no. F3063
Diagnosis
The paying company code and the company code on whose behalf the payment is being made must be in the same country, have the same local currency, and display the same currencies managed in parallel. The setting regarding extended withholding tax functions (active or not active) must also be identical for both company codes.
System Response
The entry is not accepted since these requirements are not met.
Procedure
Correct your entry.bold**
The reason for the same isCompany code 7144 is not permitted as the paying company code
Message no. F3063
Diagnosis
The paying company code and the company code on whose behalf the payment is being made must be in the same country, have the same local currency, and display the same currencies managed in parallel. The setting regarding extended withholding tax functions (active or not active) must also be identical for both company codes.
System Response
The entry is not accepted since these requirements are not met.
Procedure
Correct your entry.
The scenario is that one company code is making the payments for the other. However, the 2 companies are based in different countries. Hence, system is not allowing this assignment.
Has anyone come across this scenario? Is there any other wayaround for this which can result in Intercompany postings.
If we assign the Paying Company Code in the Variant screen in F110( instead of FBZP), will that work? I have tried the same but it doesnt work that way.
Any help on this will be highly appreciated.
Thanks in advance,
Hrishi

- i am not sure if its possible; help on FBZP clearly states this
+++++++++++++++++
The paying company code and the company code to which payment is made must be in the same country and have the same local currency and parallel currencies. In addition, both company codes must have the same settings for enhanced withholding tax functions (active or not active).
Only the valid company codes for the paying company code are included in the possible entries.

Error 0x80007114 "Outlook Express could not be started" when trying to run Migration Assitant.

Trying to run Migration Assistant on a PC (Windows XP). Error message "Outlook Express could not be started. The application was unable to initialize the store directory. Your computer may be out of memory or your disk is full. Contact Microsoft support for further assistance. (0x80007114)" Then the Migration Assistant shows a box stating that Outlook Express must be stopped before running the assistant.
I have enough memory. The disk is not full. Outlook Express runs just fine on my PC. And it was not runing at the time.
Apple Support (two tries) and my Apple store have essentially said this is a Microsoft problem. Of course, Microsoft says it is an Apple program failing so it is an Apple problem.
MS info about the error indicates that it prevents OE from starting. Than is not my situation at all. The fix is draconian (as many are) and could risk my OE so I have not gone there - yet. Hopefully there is another way.
Does anyone have any experience on how to (easily) solve this dilemma. I am also trying on the MS side.
This is my first MAC. I was convinced to go Apple by several folks who touted the excellent support. It was purchased in July 2012 and has been a boat anchor since. Support??
Thanks for any info you can provide.

So I had this as well.
I went to the file tab and went to export. From there I picked 720p and it worked. It may be different for you depending on the resolution of the video. hopefully it works for you too!

Multi-thread failure - Error in assignment

Hello
I have a c++ program processor running under Windows XP with Oracle 9i. My program access to oracle by an ODBC driver version 9.2.0.4.0. It could be launched in multi-thread to increase performance. When I launch it with one thread everything is fine. When I use several threads I have problems. ODBC driver returns to me a "error in assignment ... General error" message and my updates queries failed. Under SQl server it works without problems. It seems to be a kind of deadlock. When I disable check box in my odbc driver of "enable query timeout" my program encounter a problem and freezes...
Could someone help me ?

I have thought of the above solutions as workable, however, it is not. Some exhibited errors are:
A. "Attempt to use database while environment is closed." This error applies to 2, 3 and 4 all the way;
B. "Attempt to read / write database while database is closed." This error applies to 3 in particular;
C. "Attempt to close environment while some database is still open." This error applies to 5.
Please help me with designing a better strategy to solve the concurrent issue. Many thanks in advance.All these are expected errors. You should design the application so that you do not close an environment handle while database handles are still open, keep database handles open for as long as operations need to be performed on the underlying databases, open the database handles after opening the database handles, and close database handles before closing the environment handle.
In short, in pseudo-code, you should have something like this:
- open environment handle,
- open database handles,
- perform whatever operations are needed on the databases,
- close database handles,
- close environment handle.
You can refer to the Getting Started with Data Storage and the Getting Started with Transaction Processing guides appropriate for the API you are using, from the Berkeley DB documentation page.
