Relationship of Data

Why is data relationship (1:M and/or M:N) necessary when it comes to data modeling?
Thanks,
RG

Hi,
The cardinality (n : m) describes the relationship with respect to the number of dependent entities (entities of the target entity type of the relationship) and referenced entities (entities of the source entity type) allowed for the relationship.
With Line Item Dimension, you can assign ONE Dimension to only one characteristic.
With Cardinality, you can assign a Dimension containing Multiple Characteristics.
The possible values for the left and right sides of the cardinality have the following significance:
n = 1
Each dependent entity has one referenced entity.
n = C
Dependent entities can exist that do not refer to an entity of the source entity type.
m = 1
Each entity of the source entity type has one dependent entity.
m = C
Each entity of the source entity type has a maximum of one dependent entity.
m = N
Each entity of the source entity type has at least one dependent entity.
m = CN
Each entity of the source entity type can have any number of dependent entities.
The cardinality C:x (x = 1, C, CN, N) should be used only for relationships of the category 'referential'. (However, it can also be used for relationships of the category 'aggregating'.)
Hierarchical relationships do not allow this cardinality, since all dependent entities must refer to an entity of the source entity type.

Relationship between Date Mangement & Status Mangement in transactions

Hello experts,
Can anyone helps me with the relationship between dates & statuses in transaction.
I want to link my own date type to status "In Process".
I could not find that anywhere in the date rules linked to date type.
Thanks,
Nanda Kumar

Hi.
As Robert said this can only be done using some development.
Try to create a function module such as:

Then assign this function module to view CRMV_FUNC_ASSIGN on SM30, assign it to CRM_SERVICE_OS.
And finally insert your function module on CRMV_EVENT transaction in order to the function module be executed under some circumstance, for instance, if you want the system to execute our function module as soon as we change the status of a complaint document, so you must insert an entry such as:
BUS2000120 | 1 | 11 | STATUS | AFTER_CHANGE | E | your function name | select execute for header

Characteristic Relationship - displaying data

Hi All,
I implemented characteristic relationship (through ABAP class) and it is working fine except one thing.
It displays the desired combinations, but also posted data in infoprovider in planning mode, that were suppose to be hidden (according to char. rel. logic).
I set for all the relevant characteristics "characteristic relationship" in query designer....
Any idea what I am doing wrong?
Many Thanks!
Pavel

Hi Pavel,
sorry, maybe your exist does not work in all cases (implementation of the check method).
From your description it seems that you want to control access or maybe only make something not input ready. In the first case use authorization, in the latter use data slices.
When you say 'measures' it is also not clear for me whether you mean 'key figures'. You can not control key figures with characteristics relations, except you are using a characteristic to model key figures (account model). But again, characteristic relationships are a means to control the valid combination in the cube (so to say they define the 'truth' in the cube or what are 'consistent' data records). Data slices are a concept to protect data from being changed (typical example: lock a planning version).

Forms Builder Master Child relationship --- column datas gets hided.

Hi All,
I have a screen which have 5 columns. Out of which first 3 columns belong to Table A and 4th column belong to say Table B and the 5th column belong to Table C. There is a master Child relationship between Table A and Table B also between Table A and Table C.
The issue is, i enter the data for these columns in row wise. I enter all 5 columns with value and when i switch to next row, the 4th and 5th column's value gets hided.
Please suggest.

You have relation with
Table A with Table B
Table A with Table Cwhen you switch a record to another record at bloc/table A, it's normal forms behavior it's will hide value of block/table B and C. when your click on associate row of block/table A it will show.
It's the form normal behavior for relationship.Hope you understand.

Adding a record to a relationship | MDM data manager

Hi , Following is my situation ...
I have some material numbers in the product table in the material repository which are a part of a kit . Basically a kit is a comination of some material numbers put together . Now this kit is also in the same product table appearing as another material number . So as you can see , this is a parent-child relationship but within the same table (product table) .
Now I have defined the relationship table in the console and have also defined the type of relationship in the same . The product table is also involved with another table in a product level relationship . When i open the data manager and double click the relationship name under the record detail tab , i can see the pop-up window but it does not allow me to add any records to the relationship .
The guide tells me to use the "Relationship" menu option by selecting the number of records I want to add to a relationship and then use the relationship menu on the top of data manager , but when I tried to do that , the options are greyed out .
What do you guys think is the problem ??
Regards
Deepak Singh

Deepak,
You should be all set with setting the table up in the Console. Once you add the Parent/Child relationship there it should be active in the Data Manager.
To add parts to the table in the Data Manger:
Select a specific part (the parent part)
Double click on the child field in the relationships table
It should open the new dialog box and default to the child tab in it
This dialog box will remain open and you can move around in the Data Manager without changing this selection
Find the part(s) you want to add to the relationship as children
Select them in the Records window and drag-and-drop them into the Relationship window that is open
It should add them right in.
You should also be able to add them with the Import Manager
For Import Manger set up a file with:
Parent                  Child
Parent1                 Child1
Parent1                 Child2
Parent1                 Child3
Parent2                 Child4
Parent2                 Child5
You should be able to map this to the Relationships table and import the relationships instead of manually mapping in the Data Manager.

Many-to-many relationship with date dependency

Hi.
We have an application which manages membership of users in groups.
It is typical many-to-many relationship (table users and groups and
relational table usersgroups). So far so good.
But we would like to introduce another condition into this relationship
- date validity.
For example - person should belong to group only from date1 to date2.
I think that relational table should contain not only a couple of id's but also
a two dates (from-to) and all those four together should form primary key.
Then we should need a condition (where) for such relationsphip.
But toplink many-to-many mapping doesn't have any features for this.
Have you any idea how to implement our requirement in another way?
Thanks.

Hello,
I am not sure how you plan on setting those dates for each object in the ManyToMany collection.
The only way I can think of is to treat the usergroup table as its own entity, as a wrapper over groups (or users) in the many to many collection, allowing the application to set the date values directly. This usergroup entity would have a 1:1 to both user and group, while user and/or group would have 1:M to usergroup.

IP - characteristic relationship/ data slices

Hi Guys,
I am very new to IP and would like to have some help regarding the following with some simple example
1) characteristic relationship
2) data slices
3) locking
Some examples with the above is much appreciated.
where can i get some good document explaining this ?
Thanks in advance...

Hi,
Please find below the examples for characteristic relationship and data slice,
1. Characteristic relationship:
Consider that you have characteristics called "Country" and "Continent" in your report (also in aggreagtion level).
You cannot always expect the end user to enter the correct continent for a country. In this case, you can create a char rel
based on the relastionship between these two characteristics (attribute, hierarchy or relationship data loaded to a DSO),where the source is "Country" and the target is "Continent". So when ever the user enters country and continent the char rel validates the entry based on the reference data (master data, hierrarchy or DSO data) and throws error if it s wrong. Apart from this by creating "With derivation" char rel, you can even derive continent value from country with out the user even entering the value in thye report.
2. Data Slice:
Consider that your planning requirement is you need to plan on a monthly basis which is like during current month you caa plan for the next month. In this case all other months except the next month should not be available for planning. In this case you can create a daat slice of type "Selection" where in you select '0CALMNONTH' and then filter it to the variable '0CMONTH' +1
where in you "Exclude" this selection. So now all the other months except next month at any point of time will be disabled for planning.
You can go through the following links for your reference,
Char rel - [http://help.sap.com/SAPHELP_NW04s/helpdata/EN/43/1c3d0f31b70701e10000000a422035/frameset.htm]
Data slice - [http://help.sap.com/SAPHELP_NW04s/helpdata/EN/43/1c3d0f31b70701e10000000a422035/frameset.htm]

Extending the End Date of Relationship Org. Unit and Position

Hi All,
Please help me below.
Problem: The end date for the relationship between org. unit and position should be set back to 31.12.9999. It was accidentally been set to 31.03.9999 and results to two records in infotype 0001, which the wrong record should be deleted.
This can only be deleted by changing the relationship end date in PO13 but unfortunately, the user doesn't have any access to this transaction.
Request: Can you explain to me on how the end date can be change in transaction PPOME or PPOM_OLD as these are the only transactions the user has an access. I'd already explored these transactions but I can't find on how it should be deleted here.
Thanks!

Hi Raju,
Thanks for this information. This was a very helpful answer. But I only need to extend the end date of a particular infotype 0001 record of a particular employee. I think the report will extend all of the records of all the employees in the system. I can't find any parameter in the report wherein I can set the employee number I wish to extend the end date.
Thanks!

How to create Date relationship with Fact and DimDate on Tabular model?

I have two tables in SQL Server 2014 SSAS Tabular model.
DimDate(defined as data table) have date column (format is 1.7.2010 00:00:00) This table have been impoted from AdventureWorks.
FactSales have SalesDate column (format is 25.03.2015 18:08:05). This table have been imported from Excel. Colums is defined as date in Excel.
When I set Data Type as date in Tabular I get error:
"Datatype conversion failed for table...Value:'25.03.2015 18:08:05'"
I have tried to create calculated colums like =DATEVALUE([SalesDate]) and =DATE(YEAR([SalesDate]),MONTH([SalesDate]), DAY([SalesDate])), but getting error.
What should I do so that I can create relationship between Date column?
Kenny_I

Hi Kenny_l,
According to your description, you fail to convert the data type into date after creating calculated column with expression. Right?
In Analysis Services, the tabular will detect the source data type to determine which data type can be converted to. If you want to convert a data into date type, no matter this data is from database or a file, you must make sure this data can be recognized
as a date in SQL Server. In this scenario, the format '25.03.2015 18:08:05' can't be recognized as date even you apply DAX functions. So please change the format of the column in excel like "03.25.2015 18:08:05".
PS: For testing, you can create a temp table and insert sample text into a date column, because the date format in SQL Server depends on the location selection when installing.
After retrieving data from data source and all values within column are correct format, you can change the data type into Date, and select the format you expect.
If you have any question, please feel free to ask.

Date and Time dimensions

After reading the following article, I have decided to use SSAS dimension wizard for generating our Date dimension, which creates a DATETIME PK.
http://www.made2mentor.com/2011/05/date-vs-integer-datatypes-as-primary-key-for-date-dimensions/
I have also created a separate Time dimension as granularity of an hour is required.
The Time dimension is very simple and only contains a surrogate key (INTEGER) and actual time in hours (VARCHAR).
DimTime(TimeKey, TimeInHours)
Our Fact table will now have a link to both the Date and Time dimension using the PK's.
Our analysis is required by hour, day, week, month and year.
My query is; Will this current structure cause any problems when creating MDX scripts to analyse our data (i.e. drilldown and rollup queries) Hour - Day - Week - Month - Year

Hi Darren,
According to your description, there a day and hour granularity in your fact table, so you want to a hierarchy like Hour - Day - Week - Month - Year, right?
In your scenario, you created a time table that only contains a surrogate key (INTEGER) and actual time in hours (VARCHAR). We cannot create a Hour - Day - Week - Month - Year hierarchy without ant relationship between date table and time table. As per my understanding,
you need create a foreigner key in time table, and join those table in the data source view, then you can create such a hierarchy. Here are some links about create time dimension, please see:

How to send data from BW to third party

Hi Gururs,
We got one of my requirement that we have to send 2 files (delta and full file) from BW to Third Party system. For the delta files we have to send an after-image and we are using FI datasource.Could anybody can tell how to design it?
1. is that advicable to use the FI datasource directly to infocube as the FI datasource is AIE extractor?
2.Can we the use BWA in APD. If yes how?
3.To send an files to third party which concept can we use APD or OHD. We advised to used OHD ,but the clients are not agreeing. They asking why we cant use APD? They saying APD will be more performance. Could u pls tell why and how?
Thanks in advance...

Hi,
It is not advaisable to load FI data to IC directly, must load to DSO first.
- If client asking to use APD, you cah go ahead.
SOURCE - DSO and capture deltas
Transformation
Target - Flat File
Use-
APD helps to identify hidden or complex relationships between data in a simple way. Various data transformations are provided for this purpose, such as statistical and mathematical calculations, and data cleansing or structuring processes

Agent Determination Organizational Data

Hi Experts,
Good Day!
I would like to ask some help regarding a workflow the problem is the "user received the workitem however user claimed that he is not supposed to receive" that is why i would like to know who are the agents dedicated for these tasks. we are able to find the step it is a user decision where the agent is the Rule "0090010" for purchasing group. In transaction PFAC we entered the rule "0090010" the information regarding the rule below:
Transaction: PFAC
Rule Display:
      Basic data:
               Abbr: Purch. group
               Name: Purchasing Group
Rule Definition:
      Category: Agent Determination: Organizational Data
      OrgObj type: T024
We would like to know:
1. How does it determine the Agent who is supposed to receive mail using the "Category: Agent Determination: Organizational Data"? Where can we find the agent that is configured on the workflow using the rule?
2.Is there a standard rule for agent determination: Organizational Data for this workflow?
Answer's will be a great help.
~Thank You,
Junne Ray

got it now! sorry, i am a bit dumb today.
o.k. here is what you have to check:
transaction PFOM - relationship between the purchasing group (which will be the one of the PO and therefore and object of table T024) and your organizational structure. check the relationship.
documentation:
Data basis for role resolution
For role resolution, the link between the objects of type
T024 (individual purchasing groups) and the organization
objects (position, organizational unit, ...) is evaluated.
Required settings and Customizing
The linkages between the various purchasing groups and the relevant
organizational objects must first be maintained using
transaction PFOM.
Procedure for errors
If the role resolution delivers no result, the work item for which the
role resolution was carried out is not faulty but addressed to all
possible processors (flag "abend in role resolution without result"
is not set).

Master Detail Relationship and Posting changes!

I have a "MAster" medical-procedure block, and an "Detail" items block. The items block, being the detail block, in the master detail relationship shows the items used during the medical procedure. Both the master and detaqil blocks are based on stored procedures.
Problem: I have multiple medical procedures (multi record master) and many items associated with the procedure (multi record detail). If I ask the user to "SAVE" the changes, after every detail entry ( for the correspondin master), it becomes a "PAIN" for the user. He wants to be able to choose a procedure, choose the details(items) associated with that procedure, and move on to the next master record, (the next medical procedure) , select it, if he performed that procedure, choose its corresponding detail items, "WITHOUT SAVING IN BETWEEN" navigation between the master records / "MEDICAL PROCEDURES"!
1. Is it better to go for a master-detail relationship? If so, how do I prevent the "Please save the changes" when navigating between master records and ALSO save the details, without doing the "SAVE" multiple times. Can I go for a post ?..If so where? When-new_record instance/ any "Form level trigger"?
2. If I do the go_block('dtl blk name'); execute_query; thing to coordinate between blocks, and "post" changes in the when -new -record-instance of master, the detail complains of a null value when I move from a medical procedure to another medical procedure which is not actually performed.
I hope I make sense, any suggestions , "Welcome"!
Thanks!

Hi,
I'd suggest to check this tutorial:
http://www.oracle.com/technology/obe/obe_as_10g/bi/forms/formsmasterdetailobe.htm
Having a relationship between data blocks, coordinates dml actions in both, so no coding is needed to save/update/delete records, forms built-ins do the work.
hope this is useful,

Backing up all data and objects of Oracle 10g Express Edition...

Hi,
I have tables, packages, views, procedures, etc. in Oracle 10g Express Edition, running on Windows XP. I would like to create a backup of the complete database (objects, relationships, all data, etc) into a file that I can restore in case the database crashes.
What do I do?
Thanks.

I am actually using it for Production. Yes, I would need objects and data.I would suggest to look at the Standard Edition as well if you are using it for production.
Is there a way to backup everything without data and then backup everything with data? Also, is there a way to restore everything without data and then restore everything with data?What's the meaning of "backup everything withiut data" and "then backup everything with data" ? The data is in the tables alone. The rest of the objects are not containing data but are using it, be it views, procedures etc. There is no such restore like without data. Without data, all what you would be getting would be structures of the tables which is going to be of no use. The export/import tool, is a simple tool which can put the tables (and other objects as well) along with their data in your dumpfile . In the situation of loss of a table, you can do an import from that dump file and you can restore the table back(with or without data, depends on the choice of yours while running Import command) . But this is just going to be a logical recovery of the object(s). For a complete database, it's better to use RMAN which would copy the datafiles and keep it with itself. Later, when you have a crash, you can restore those files to get teh database recovered. But if you want complete security, its better to put your db in the archive log and then do the backup along with the archive log files.

How to do this exactly? Thanks!

Tool to transfer data from one CRM system to another

Hi,
We are merging one CRM system into another and need to transfer master data and transactions from one CRM system into the another. What are the options/tools that are available for data migration in CRM 7.0?
Please share experiences/thoughts if you have moved data into SAP CRM from legacy/other SAP CRM systems.
Regards
Dan

Hi Dan,
Looking at your post - I decipher that you would be doing download from a lower version of SAP CRM system to SAP CRM 7 if this is the scenario then you have an advantage as you could employ standard SAP CRM middleware which is a powerful application to download master data from older version to new version, or else you could ALE the master data. Now this being the simple part we move on to the harder part of the migration which is transactional data - namely elements such as Number ranges, document flow, relationships, condition data tables .....etc if you are migrating this from lower SAP CRM version here you would have to understand the interlinking with R/3 or ECC6 in any case you would have to do a fresh implementations but on the whole there are some way outs for examples ; But still let me know how you intend to migrate and what are systems we are talking about.
With compliments,
Tarovar.
