DATE Field in composite key

Hi experts.
I have a small query.
Is there any performance impact of having a date field along with four other fields as part of a composite key.

When you add an index, there is definitely some overhead to get the index synchronized with newly added/updated data (so whether you have indexed NUMBER, CHARs or DATEs does not matter - but I could be wrong in saying this).
Concerning your SELECTs, if your existing queries were using this index then they may or may not use the new index (due to cardinality and other factors); so you need to test this first.

Data fields and key fields

Hi,
Data fields and key fields are same as Characteristcs and key figures? Or they are diffrerent?
Thanks,
Radha

HI
Key Fields = Acts as Primary Key for The ODS like Primary of Tables in R3.
Data fields = Apart from Key fields We consider rest as data fields.
Ususally we use Characteristic info Objects and Dates in Key Fields and Key figures in Data fields.
It's decisive factor for overwriting property of ODS or DOS.
Hope this helps.

How do I set blank data to date field in pdf form ?

Dear Sir,
I made PDF form by Acrobat X on Windows PC and then,
read the pdf form by acrobat reader on iPad.
Date field is included in the form.
The Acrobat version is 10.1.6 .
The acrobat reader version is 10.5.0 .
First, I put the wrong date data to the date field.
So, I tried to clear the date field.
I want to put the blank data to the date, but I think
there are no way to put the blank data on iPad
I would like to know how to reset the date data.
If that helps, I tried to the same thing on Android.
I could put blank data to the date field by BS key.
Sincerely,

Here is how to clear the Date field on the Ipad.
NOTE: In order for this to work that has to be another TEXT field in the PDF to get the keyboard to pop-up.
Click on Text field (this is to get the regular keyboard on screen)
Click on Date field (date spinner control will show up)
Click on SAME DATE field (spinner control will disapper)
Click on "Reset Field" on top of keyboard (date field will now be empty)
Click any where on PDF that is not another Date field (keyboard will disappear and date field will be empty)
Bingo! your free and clear.

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:

Key Fields & Data Fields in DSO.

In Standard DSO, Maximum how many number of key fields and data fields we can enter in one DSO?
For e.g : In Cube Char - 248 KF - 233
In DSO Key Fields - ? Data Fields - ?
Regrards,
Nithi.

Hi Nithi,
Since Key fields are decide by us we can add according to our requirement.
Key fields can only be 16 you cannot exceed this. but if you have more key fields, you can combine fields using a routine for a key field
Max Data Fields - 749 data fields can be added in a 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
SG

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.

Data Fields & Key Fields IN DSO

Hi Guys,
Can any one tel me what exactly key field holds & Data field hold in DSO.
Thanks,
Venkatesh

Hi,
A DSO serves as a storage location for consolidated and cleansed transaction data or master data on a document (atomic) level. This data can be evaluated using a BEx query.
A DSO contains
Key fields (such as document number, document item) and data fields that, in addition to key figures, can also contain character fields (such as order status, customer). The data from a DataStore object can be updated with a delta update into InfoCubes (standard) and/or other DataStore objects or master data tables (attributes or texts) in the same system or across different systems.
Key fields : It will contains both Chars and KeyFigures.
Data Fields : Based on this i.e. the charecterisctics which you will keep in this Data Fields, the DSO will over write the Data in DSO.
Overwriting functionality will works based on Data Fileds.

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

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..

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

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.
Regards,
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.
