How to create SCD2 type manually in informatica?

Please Can you describe with example how to create SCD2 type manually in infromatica?

Hi Manoj,
You should not delete the auto generated orchestration even do not modify it, as it is stated in msdn.
The BizTalk WCF Service Consuming Wizard creates in your BizTalk project the BizTalk schemas and types necessary to consume WCF services. The BizTalk types such as port types and multipart message types are created in an orchestration. We recommend
that you do not modify the orchestration that the wizard creates. Instead, you can add new orchestrations in the BizTalk project for your purposes.
--------- MSDN
For Refernce
In your solution, if you are seperating your schemas project from orchestration project, in that case i personally advise to generate wcf endpoint in your schema project and after adding schema reference in orchestration
project you manually create the multipart message and a request response port as it will not display in existing port.

How to create document type ?

Hi experts
We need assign document type to mateiral in material master. So we need create new document type background. How to create it ?

Thanks

Hi Alice,
You have create document type from

How to create movement type

hai sap gurus,
can u clarify my problem,
how to create a movement type and where we assign that movement type to gl account
clarify please

Hi Ram,
You can create Movement type in OMJJ transaction by Copying the existing mvt types. Once you copy the mvt type all the details from the existing mvt type will be copied to new mvt type.
Based on the Account grouping the system will identify the G/L accounts. You can check this OMJJ transaction you will get better idea.
One more thing why you need the new mvt type, if it is really required then go for new mvt type otherwise use the SAP standard Mvt type which will serve all the purposes.

How to create table type in SAP3.1i ?

Hi Friends,
Is it posible to create table type in SAP 3.1i server ?

Hi amit,
I think there were no table types in 3.1i. Still you can define a structured table, i.e.
DATA: BEGIN OF SORT_SPFLI OCCURS 100,
        CARRID   LIKE SPFLI-CARRID,
        CONNID   LIKE SPFLI-CONNID,
        CITYFROM LIKE SPFLI-CITYFROM,
        CITYTO   LIKE SPFLI-CITYTO,
        SFLIGHT LIKE SORT_SFLIGHT OCCURS 100,
      END OF SORT_SPFLI.
You can use field-symbols, but no loop assigning.
What is it you want to do?
Anyway: Have fun with good old 3.1 - I put my old docu CD in the trash recently.

How to create a type table in designer 9i

Hi
In our company we use designer 9i. I want to create a type table using designer. Is it possible? I have a requirement where i need to create a type table and use in creating a view through designer.
Create or replace type varchar2_ntt as table of varchar2(4000);
[\pre]
Please suggest.

Hi
Here I am giving the step by step process.
1. select the container in which container you are going to create the type.
2.Go to tools then design editor and expand the container. There you will find oracle collection types. there we have to create a new one by clicking the + button on the left side.
3. Give the name of the new collection type.
4. And in the collection of tab, let it be scalar, give the scalar data type,and the size and click finish.
5. then right click on that object and give generate. there you select theDDL files only and the give the path where the scripts have to go.
This the process.
Thanks,
raju
