Query regarding algorithm resource estimation at system generator (VIVADO IDE- 2014.3.1)

Hi Guyz,
I am able to estimate the resource required for a design only after the synthesis is done in the Vivado.
The question is:
Is it possible to estimate the resource in system generator (Vivado IDE 2014.3.1) itself ?
Couldn't find the RESOURCE ESTIMATOR block in the system generator [xilinx blockset/tools] as in its precursor, i.e. System generator (ISE).
When i went through the documents, came to know that resource estimator block has not yet been introduced in System generator - Vivado IDE [Please correct me, if i am wrong]
Is there any way [other than checking utilization report after synthesis], which will allow me to estimate the resource as soon as the algorithm is ready - as a system generator model ?
PLEASE GUIDE.
THANKS in advance.
Thanks & Regards,
Ananya

Hi Satish,
Thanks for the quick reply.
My doubt:
Can I find the resource estimation for the algorithm model using ISE and then approximate the resource at Vivado ? [Not sure if this makes sense, just wanted to know if this approach works]
Please suggest.
Thanks & Regards,
Ananya

How to delete a system generated query

Hi,
I want to delete a system generated query without doing which i am not able to delete a field from field group.
Regards,
Sharadha

sure.
I have a infoset with some fields.
I want to delete a field from a field group. When i try to delete,it displays 'Field is used in a query, so cannot delete' .When i saw the query for the field all are system generated queries..i.e usergroup is SYSTGENERATE.
I tried to take the query id from there and tried to display the querym but it says query 'SY000000xx' not generated.
How to delete this query?
Any suggestions?? Is it not possible??

Query regarding SCN

Good day gentleman,
I have a query regarding SCN, how can I know the current status of SCN(in oracle 9i) database , is there any view for that.
I will also be grateful if some one will tell me on which events Oracle generates a new SCN number.
With Regards
Anshuman

Sir..
The current system SCN can be queried using dbms_flashback.get_system_change_number.
The SCN of the last checkpoint can be found in v$database
Virtually.. each time a modify takes place the scn is increased.

System generated number

Hi all,
I m developing a module pool with z table 1 Header & 1 Item table. Now I would like to ask how I can get system generated number for the pk filed supose gate pass number and my filed type is char 10.
When user enter a new entry then system will auto generqte the gpass number .
so pls let me know if any one can help me to do this job.
Thanks in advance.

Hey Manju,
first pre determine what range your number should be having , like starting from 0000000001 like that or 1000000001 etc, after that :
Scenario 1 ( if you have to show the number as a field on the screen)
write a select query in the PBO of the screen as below
let the field name be gateno.
select max(gateno)
from <dbtab>
into < var1>.
this will fetch the last number and then you can increase it.
if syst-subrc is initial.
var1 = var1 + 1.
endif.
move the value of var1 to the screen field name.
Scenario 2 ( If you just need to update in the database table)
write the above select query in the PAI module of the screen when the user performs some action like SAVE.
Hope this helps,
reward if useful,
Regards ,

Confusion over nested tables and system generated nested tables

Hi,
I have been reading other threads about nested tables, naming and updating them etc, but I have what seems
to me some odd behaviour.
I modified my schema to set the attribute xdb:maintainDom to be false for a collection and then registered
the schema with the generate tables option defaulted to true. The result was that I had to add xdb:tableProps
attributes specifying nested table storage at each element above the collection element, this was because Oracle
was creating tables at each level. So I have this kind of thing:
<xsd:element name="BibPt" xdb:SQLType="BIBPT_T"
xdb:defaultTable="BIBPT"
xdb:tableProps="NESTED TABLE XMLDATA.PTEES.PTEE_SEC.PTEE STORE AS NESTED_PTEE_SEC
NESTED TABLE XMLDATA.INVS.INV STORE AS NESTED_INV_BIBPT TABLESPACE BIBLIO">
<xsd:element name="Ptees" xdb:SQLType="PTEES_T" xdb:tableProps="NESTED TABLE
XMLDATA.PTEE_SEC.PTEE STORE AS NESTED_PTEE_SEC2">When I did this the nested tables were created, but when I loaded data never had anything in them. Instead
I found that nestes tables with systems generated names like "SYSNTxxxxxxxxx" has been created that contained
the data.
When I registered the schema without the tables being generated, I created a table with this syntax:
create table poc_wip2 of xmltype
xmlschema "http://www.derwent.co.uk/wpi.xsd" element "WPI"
NESTED TABLE XMLDATA."BibPt".PTEES.PTEE_SEC.PTEE STORE AS NESTED_PTEE_SEC
NESTED TABLE XMLDATA."BibPt".INVS.INV STORE AS NESTED_INV_BIBPT(Thanks to a posting by Sam Monsarrat which showed me this was possible).
Now I had my named nested tables, which contained the data after it was loaded and no system named
nested tables.
So why the difference?
In the first instance why do my named nested tables stay empty and why does the data go into system
generated tables I have no control over as regards tablespace placement?
Is it possible to have a XML schema registered that only generates tables that I have named with the defaultTable
attribute, rather than all or nothing?
And last but not least, what's the best approach for this, since I want to be able to access the data via indexes
on the nested tables.
Thanks
Pete

Hi Pete
Would you please publish the schema you are using?
Thanks,
Tobias

Query regarding the conversion of DME file in MT940 format.

Hello Experts,
I have a query regarding the generation of MT940 file after generating the payment file from other DME tree.
After completion of payment run, my payment file is generated in the DME format which is according to the DME tree.
I want to convert the DME file (which is generated via F110) from existing format to the standard MT940 format.
Is there any standard program which converts the DME file to MT940. If so, please inform me as early.
I have tried to upload the DME file in FF.5 transaction, but it is not allowing me to convert the file in MT940 structure.
Or please inform the steps how i can convert the file .
Awaiting for your inputs.
Thanks in advance

Hi Zareena.
I would like to suggest,

System generated index property not generated in database

Hi,
I created an offline table by copying it from an (first) online database to my project. The table contains a unique key constraint, which references a system generated index. Now I used this offline table to generate a table in another (second) online database. This all works well except, that the "System Generated" property of the index is "false" and not "true" as in the offline table (and the first online database). When I manually reconcile the same table to the second online database again, there is always a difference shown for this index property. When I try to continue the reconcile process to change this property I get an error message, that the index cannot be dropped because it is obviousely referenced by the unique constraint.
When I drop the constraint and try to generate the index only I get the following warning message:
Jan 11, 2012 2:08:59 PM oracle.javatools.db.property.AbstractPropertyManager processDiffs
WARNING: Unsupported property: systemGenerated
Is there a way to work around this annoying behavour? Is it possible to change this index property by an ALTER INDEX statement?
Im using JDeveloper 11.1.2.1.0 (Build JDEVADF_11.1.2.1.0_GENERIC_110907.2314.6081)
Thanks for help and hints

Hi,
it might be due to some BUG in RDBMS...
First Check the Secondary index in TEST system
Look at the Transport Number in DEV system, If this is having error, then it will show you the error details also,
If that not moved Properly then you need to create another request for the INDEX and move it again
See the threads with similar problem...
Warning: Index does not exist in database system MSSQL
Index does not exist in database system ORACLE??????
Re creation of database index
Hope it will solve your problem...

How to block changes in system generated Plan orders

Hi,
As after MRP RUN we get Planned order generated by the system, with type LP , I have a requirement that system generated plan order quanity cannot be cnhage by the user if plan order is generated for quanity 85 user should not make it 100 no quality chnages, also the manual plan order type LP cannot be create manully it should be creat by system only, and for manul other type of plan order type should be use,
How to do this.
regards,
zafar

Hi
Firming can be used when you don't want certain planned orders to change during subsequent MRP runs.
Say today you have created certain palnned orders.
In a normal scenario, when you do the MRP run again, the planned order may get changed if the requirements have changed.
However as a normal business practice, it is not desired to change the production plans everytime there is a change in the requirement...especially in the immediate future (maybe a week or so).
We set this as the planning time fence depending on the MRP type settimg in the material master, you may have firm orders.
MRP will also generate firm planned orders for materials with MRP type P1 to P4.
In addition to the above, any planned order that is manually changed is also firmed.
Hope this may help

How to work around System Generated ID's - GUID?

Hello Experts:
We are facing a challenge in our CPROJECTS and CRM modules.
All the objects are getting assigned a unique 32 character system generated ID which is linked to the actual object. This makes navigation and troubleshooting even more complex.
My questions are these:
1. What is the significance of this methodology of assigning System generated ID's (GUID's)? Why do we need these system generated ID's?
2. How can we convert the objects from internal ID format to external ID format? Is there a function module that would allow us to do that?
3. All the business content extractors are designed to extract in the internal ID format. What do we do to configure the extractors to use external ID format.
Any helpful answer will be rewarded.
Thanks

Query regarding using JNI in linux

Hi
I have a query regarding JNI.We have a situation in which
we have some c programmes and we want to call that c programme method in my java code. The problem is that in JNI the native code signature should match the signature of the method of the header file generated by javah. We donot want to change the signature of the native code since it is hard to debug.So please suggest me a way out that i can call the native method without changing the signature of the native code.Please if u could give me some few simple example
Thanking u

So please suggest me a way out that i can call the native method without changing the signature of the native code.You write a wrapper. Your java JNI class has methods. Those methods are written in C by you. Those methods are new code. Those methods call your existing C methods.
Please if u could give me some few simple example.http://java.sun.com/docs/books/tutorial/native1.1/index.html

Do we need to create process chain explicitly nor system generates process

Hi all,
Do we need to create process chain explicity in bpc netweaver nor the system generates it internally when we run data managment packages
thanks
Pooja

When you install BPC, there is a set of delivered process chains which are installed as well. You create the data manager packages from the BPC Excel clicent based on these process chains. You can of create custom BPC process chains in NetWeaver and create packages from those as well(for example via a How-To guide). So to answer your question, no, you do not have to create the "standard" process chains, and they are not generated by the system either, they are delivered as part of the BPC installation.

System generated emails - how to include a mandatory prefix for all email

Good morning.
I have been asked if there was a way to default a Security Classification into the Subject Line of all SAP system generated emails.
Examples "[UNCLASSIFIED] Please approve Purchase Order 123456" or "[UNCLASSIFIED] Please approve Absence for Fred Smith".
I can have the individual code of the Programs that generate the Subject Texts but is there a way to have this default for ALL emails?
Thanks
David

Hi David,
This one sounds like the one for the Basis guy to look at. They should be able to configure (default) this prefix in the EMAIL/SMTP node(s) as viewed in transaction SCOT. The changes should be done from the IMG (SPRO).

OIM - query regarding child tables

Hi All
I have a query regarding child tables. For example, when a user is removed from an AD group, his corresponding entry from the AD groups child table will be deleted. I want to know whether it is deleted of marked as deleted. Can I get the information later on that the user was removed from which AD group?
Please help.
Thanks

You will have to enable the audit level = Resource Form and perform the additional tasks to track the process form data changes. This will track all modifications to the forms.

Urgent query regarding performance

hi
i have one query regarding performance.iam using interactive reporting and workspace.
i have all the linsence server,shared services,and Bi services and ui services and oracle9i which has metadata installed in one system(one server).data base which stores relationaldata(DB2) on another system.(i.e 2 systems in total).
in order to increase performance i made some adjustments
i installed hyperion BI server services, UI services,license server and shared services server such that all web applications (that used web sphere 5.1) such as shared services and UI services in server1(or computer1).and remaining linsence and bi server services in computer2 and i installed database(db2) on another computer3.(i.e 3 systems in total)
my query : oracle 9i which has metadata where to install that in ( computer 1 or in computer 2 )
i want to get best performance.where to install that oracle 9i which has metadata stored in it.
for any queries please reply mail
[email protected]

You should know that executing a query is always slower the first time. Then Oracle can optimise your query and store it temporary for further executions. But passing from 3 minutes to 3 seconds, maybe your original query is really, really slow. Most of the times I only win few milliseconds. If Oracle is able to optimize it to 3 seconds. You must clearly rewrite your query.
Things you should know to enhance your execution time : try to reduce the number of nested loops, nested loops give your an exponential execution time which is really slow :
for rec1 in (select a from b) loop
for rec2 in (select c from d) loop
end loop;
end loop;Anything like that is bad.
Try to avoid Cartesian products by writing the best where clause possible.
select a.a,
b.b
from a,
b
where b.b > 1This is bad and slow.
