Difference b/w KEY FILEDS and DATA FILEDS

Hello Experts...!
What is the difference between char , KF and keyfields and data fileds...?
we are going to map this in the ODS concept.
char to keyfileds.
keyfig to datafields.
regards,
amit.

Hai Amit,
In ODS Key fields means the Primary keys characteristics.
So when ever we map the primary key characteristics (ie characteristics on which some info objects are dependent) should be assigned to key fields
and to data fields the Key figure Infoobjects as well as characteristics which does not have the primary/in-dependent fileds

DSO - What key fields and data fields in dso

Hi experts,
I need to create a dso in between the cube and 2 data sources(2lis_11_vaitm, 2lis_12_vcscl) to stage the data. My question is: what key fields and data fields to choose for the dso? is there a standard dso to copy? please explain in detail the model to set up, whether to connect both the ds's to dso and then to cube or one ds to dso and the other to the cube. more details will help.

Check this for standard DSO:

Infoset Join condition on Key feilds and data fields

Hi Guys,
I have a requirement to biuld the Info set with join conditon on two DSO's the info objects which i am using in the JOin condition are defined as data fieds in one DSO and defined as key fields in another DSO, is it possible to define join condition on key fields and data fields.
The two info objects are
                       0AC_DOC_NO
                       0ITEM_NUM
These two info objects are defined as data fields in DSO :   0LIV_DS1   Invocie verificaion
                                                        key fields in DSO:    0FIAP_0o3 FI AP Line Item
Please suggest me is it possible to define join the condtion on the data fields and key feilds.
Thanks
Best regards

Hi
yes you can create join, you will get any issue in reporting level.
example: Say i want to create Info Set on 0MATERIAL and Sales DSO.
In 0MATERIAL Info Object it is key filed, but in my DSO 0MATERIAL is data field.Still we can create
Creation of join is dependent on fields common in your source objects.

Key fields and data fields in a DSO ??

i have a question regarding key fields and data fields in a Standard DSO...
i am using 2 datasources to build a open sales report 2LIS_11_VASTH and 2LIS_11_VASTI i am pulling in data from these 2 data sources to a DSO and i am wondering what infoobjects should be in the key fields and data fields .....does this reflect back to table VBUK and VBUP tables and does the key field in the DSO have to be the key fields in VBUK and VBUP tables ???? or what really should be included as key fields and data fields ????
please help....

If you look at the various SD tables, VBELN and POSNR are commonly used as the document number and document line item.
For VBAP and VBUP, it's referring to the Sales Order Line Item with the columns VBELN and POSNR as the key for both tables. However, if you look at the LIPS table, which is the Delivery Line Item table, it too has VBELN and POSNR as the key. Likewise, the VTTP table, which is the Shipment Line Item table, also has VBELN and POSNR as the key.
While using RSOSFIELDMAP as a map is a fairly good "rule of thumb", it still needs to be used with a level of skepticism.

Prerequsites for deciding Key fields and data fields

Hi
I would like to know the criteria to decide upon KEY fields and Data fields for an infoprovider.

Hi,
What is a Key field in a Database and How should I choose one?
Keys are crucial to a table structure for many reasons, some of which are identified below:
They ensure that each record in a table is precisely identified.
They help establish and enforce various types of integrity.
They serve to establish table relationships.
Datafields may be Charecteristics and it may be keyfigures

Marasa.

Identify key fields and data fields

Hi
i have datasource 0co_om_cca_9 .
i want build 1 DSO, how can i identify what are key fields and data fields to build DSO based on that datasource.

Hi sunnel,
The DSO are like 2-D database tables.
We use the technical keys here in counterpart to the business keys in Infocubes.
The key fields are the one based on which the records are identified uniquely in the database table.
And the data fields are the ones which are aggrgated or summarised or overwritten based on the value in key filed.
For example:
The ID no.s of the employees will be unique and it can be used as a key field.
The feilds like the Salary taken by the employee every month :"SALARY"
and the no. of leaves they taken: " NO. OF LEAVES" can be used as data fields.
So that the salary or the leaves taken by a particular employee can be aggregated based on her/his ID no.
The key fields in DSO doesnty mean Key figures.The key field means any unique key or a key based on which the records are sorted in the DSO
And key figures are the data fields.Some of the Characteristics can also be data fields in DSO.
Please give points if u r satisfied wit the information
Also let me know if u hav any doubt and if any thing is wrong.

Kalpana M

Defining Key -field and data fields

Hi all
i have to define Key-Fields and data-Fields for a DSO(say DSO3).
DSO1 is a combination of DSO2 and DSO3..
DSO1 and DSO2 are SAP defined DSOs.
DSO3 is a User defined DSO.
my assumption:
   DSO3 has 30 fields
   DSO2 has 16 fields.
   can i create the DSO3 with remaining 14 fields which is there in DSO1?
   or i have to create the DSO3 with 30 fields(all DSO1 fields).
can any body explain....
Thanks & Regards
krishna

The problem is not how many fields you create where, the issue is where is the data is going to come from.
Since you data is going from DSO3 to DSO1and if the field is already getting populated in DSO1 from DSO2, then you don't have to worry about populating those fields again, unless and otherwise you want to overwrite them.
Remember any fields exist in both DSO3 and DSO2 which overlapping will be overwritten by the latest update.
Again, going back to your question, you should consider does your datasource has missing fields (14 of them).
thanks.

Difference between cellular/voice network and data network?

Hey guys, so I'm trying to learn this, any help would be greatly appreciated.
What is the difference between cellular networks (I assume voice calls) and data networks (sending and recieving data, like using apps, etc.) for each of the different carriers?
I tried researching this up, but with absolutely no luck. Any help towards understanding cellular networks and the difference if any between it and data networks would be helpful! If you can point me in the right direction, it would help too!
Also, in the presence of a voice network but no data network, can data still be transmitted? Any values for speed for the major carriers?

Try "Cellular voice vs data" as a Google search.
From that search, this article should help:

Difference between Key feilds and Data fileds in ODS

Hi team,
What is diff between data fields and Key fileds in ODS ?.
Pl let me know.
Regards,
Senthil

Hi
Key fields:
Unique identification of record: uniqueness of a record in ods is maintained by how you define the key fiedls in the ods. key fields in the ods are equal to the primany indexes on a table.
If you activate the ODS it will generate a Table with Primarykey which you defined in the ODS.
Datafields:
data fields that can also contain character fields and keyfigures.

Key fields and data fields re-arranged

Hello SDN,
Which design contains more records due to it showing more granularity? :
1. ODS with more infoobjects assigned as Keys.
2. ODS with less infoobjects assigned as Keys.
assuming the total number of infoobjects remain the same.
Where data fields can contain characteristics that can be used as keys or non-keys, depending on choice of design.
My understanding is with more keys, less details available due to aggregation. Could you kindly help to confirm this is correct?
I need to ask this because I am trying to change the re-arrange the keys by putting data fields as keys but not sure how this will turn out / behave.
Thanks,
Suzie

Hi,
BUT! I cannot say that it will increase. That means, I think the record number remains the same!
I do not think that this is Right?
for ex:
1)
Key fields:
Billing document
Data Fields
Sales Office
Customer
Net sales
So in the update rules , you can see the Overwrite for all Data fields. If the sales office is chaged for a record , the the OLD value will be over written by new value. So Before and after change to the records, the no of records are equal to 1.
2)
Key fields:
Billing document
Sales Office
Data Fields
Customer
Net sales
So in the update rules , you can see the Overwrite for all Data fields(now not for 'Sales Office'). If the sales office is chaged for a record , the the OLD value will not be over written by new value. It creates 2 records in Active table with respect to one change in new table. So Before the change , the no of records was 1.now after change, the records' number becomes 3.

Key Fields and Data Fields in ODS

Hi Guru's ,
Can u Explain what are Key Field's and Data Field's in ODS,and How they work.
Thanx in Advance.

Hi Pradeep,
An ODS key fields forms a unique combination of chars according to which data in the ODS will be summed up. Data fields are additional fields, chars or key figures.
For example, you have the following key fields:
Doc No, Doc line item (item no in the doc) and you load the following data:
Doc# Item# Amount CALDAY
1234 1        100       26.09.2005
1234 1        150       27.09.2005
1234   2        300      27.09.2005
1235   1        400      27.09.2005
The first two rows with the same key fields (1234-1) will be aggregated and into ODS will go amount of 250.
What I said is true if for Amount key figure the Add option is set.
But if you set an Overwrite option, then the second record will overwrite the first one and only amount of 150 will go to ODS!
But if CALDAY is also a key field, then into ODS will go all records without any aggregation, because key fields combination is different for all records.
So, ODS key fields choice and KFs settings are very important for data aggregation in the ODS.

Eugene

What is the difference between /assets/account/import and /data/account ?

Does anybody knows what is the use of /assets/account/import and /data/account.
What is the difference between these two and their functional use.
thanks

/assets/account/import is used in the context of performing account file uploads through the E10 UI. If you navigate to Contacts > Accounts > and click Upload in the top right corner (above search), you'll get the upload wizard:
The moment you click the cloud icon and select a file, two actions take place:
1) POST to /assets/account/import is made, where you are passing the name, import source and purpose of the import. The response includes the id of the new import object you created
2) Another POST to /assets/account/import/{id}/csv is made, which includes the data in your chosen file
Afterwards, you perform the mappings and go to step 4 of the wizard. When you click Finish, another two actions take place:
1) PUT /assets/account/import/{id} to update the import definition with your mappings from Step 3
2) POST to /assets/account/import/{id}/queue to send this import into the import/upload queue. At this point it becomes visible from Setup > Integration > Inbound > Reporting > Upload History
Note that this workflow is not meant for client use, but rather helps facilitate UI functionality for marketing users. You should be using Bulk API to add or update records, which also confers other advantages such as the ability to use syncActions. The only functionality not available in Bulk API which is available through this workflow is the ability to delete Accounts. For obvious reasons, its recommend that you do NOT automate the deletion of any records. Accounts especially are not subject to any band limits or rates, so its best to have Marketers remove them as needed.
Regarding the second part of your question, the /data/accounts endpoint will provide you with up to 1000 account records when using GET. A POST can also be made to create a new account record (company) within Eloqua. Otherwise, GET /data/account/{id} will retrieve the details of a particular record and PUT /data/account{id} will update a particular.

Difference between physical standby database and Data Guard

Hi guys,
Today I attended one interview. They asked me a difference between the Oracle Physical Standby database and Oracle Dataguard?
Upto my knowledge Oracle Physical Standby Database is one type of Standby Database can be configured using Oracle Databaguard Feature.
Can you people calrify me on this.
Regards,
Vijayaraghavan K

hello,
yes you are right upto some extent...here is para form oracle doc
Oracle Data Guard is the most effective and comprehensive
data availability, data protection, and disaster recovery solution
for enterprise databases. It provides the management, monitoring,
and automation software infrastructure to create and maintain one
or more synchronized standby databases to protect data from failures,
disasters, errors, and corruptions.
Data Guard standby databases can be located at remote disaster
recovery sites thousands of miles away from the production data center,
or they may be located in the same city, same campus,
or even in the same building. If the production database
becomes unavailable because of a planned or an unplanned outage,
Data Guard can switch any standby database to the production role,
thus minimizing downtime and preventing any data loss.oracle data guard is maximum availiblity solution which maintain physical standby databases and in case of failure of production can switch production role to and standby database.

ODS Key Fields and Data Fields

Hi Gurus,
While creating an ODS how do we decide whether a characteristic has to be defined as a key field or a data field.
Thanks,
KR

Hi KG,
Key fields in the DSO are the primary keys in the active data table, depending on the keyfields the data in the aggregates will be overwrited.
It depends on the requirement we will decide what are the keyfields has to be taken. To utilise the overwrite functionality of the DSO depending on the data which is coming into bw we take keyfields. If u are using DSO as a staging then u have to lookinto the corresponding tables of the DSO, what are the primary keys in those tables..

Exact difference between tolerance key AN and AP

HI,
Can any one tell me exact difference between the tolerance keys AN & AP with examples?
Thanks& Regards,
Pushparaj S.

Hi Swetha,
So, do you mean that AN & AP are the same as per the functionality wise. but only AP can allow further filter of the items as per the additional setting for item category?
For example:
Custo:
AN: upper limit 100 EUR
MIRO:
IR: Item 1: Item category: "L" exceeds 100 EUR
IR: Item 2: Item category: "Standard" exceeds 100 EUR
Result:
In this case system will block both items...
Custo:
AP: upper limit 100 EUR
Item category: "standard"
MIRO:
IR: Item 1: Item category: "L" exceeds 100 EUR
IR: Item 2: Item category: "Standard" exceeds 100 EUR
Result:
In this case system will block only item 2...
Please confirm this...
Thanks & Regards,
Pushparaj S.
