Doubt on generic

hi bw gurus,
i am having one doubt in generic deltas. if you are using calendar day for generic deltas suppose if i extracted data today and there are deltas posted after 3 pm. if i want to extract delta records after 3 pm. is the calendar day option will work fine for that. or what is the scenario explain.
explain about the safety intervals how it works will calendar day.
what is BCS. can any one provide me the material for BCS.
good links and good answers will be given points.

Doubt Reg Generic Delta "Safety Interval" Setting

Hi Experts,
I have a doubt regarding Setting "Safety Interval Upper Limit" and Lower limit in RSO2 for generic delta.
What does this setting imply?
If I do setting for calender day say both 1 then wht will be difference between delta before setting amd after setting?
Plz explain in terms other tham help provided...
Points will be awarded to say thanks..
Thanks in advance,
Sorabh

Hi Sorabh,
Here some SAP informations:
Safety Interval Upper Limit of Delta Selection
This field is used by DataSources that determine their delta generically using a repetitively-increasing field in the extract structure. The field contains the discrepancy between the current maximum when the delta or delta init extraction took place and the data that has actually been read. Leaving the value blank increases the risk that the system could not extract records arising during extraction. Example: A time stamp is used to determine the delta. The time stamp that was last read is 12:00:00. The next delta extraction begins at 12:30:00. In this case, the selection interval is 12:00:00 to 12:30:00. At the end of extraction, the pointer is set to 12:30:00. A record - for example, a document- is created at 12:25 but not saved until 12:35. It is not contained in the extracted data but, because of its time stamp, is not extracted the next time either.
For this reason, the safety margin between read and transferred data must always be larger than the maximum length of time that it takes to create a record for this DataSource (with a time stamp delta), or it must display an interval that is sufficiently large (for determining delta using a serial number).
Safety Interval Lower Limit
This field contains the value taken from the highest value of the previous delta extraction to determine the lowest value of the time stamp for the next delta extraction. For example: A time stamp is used to determine a delta. The extracted data is master data: The system only transfers after-images that overwrite the status in the BW. Therefore, a record can be extracted into the BW for such data without any problems.
Taking this into account, the current time stamp can always be used as the upper limit when extracting: The lower limit of the next extraction is not seamlessly joined to the upper limit of the last extraction. Instead, its value is the same as this upper limit minus a safety margin. This safety margin needs to be big enough to contain all values in the extraction which already had a time stamp when the last extraction was carried out but which were not read. Not surprisingly, records can be transferred twice. However, for the reasons above, this is unavoidable.
Extracted Data Delta Type
The system uses the delta type to determine how extracted data is to be interpreted in BW, and into which data targets it can be posted.
A distinction is made between the following:
1. Additive delta
The key figures for extracted data are added up in BW. DataSources with this delta type can supply data to ODS objects and InfoCubes.
2. New status for changed records
Each record to be loaded delivers the new status for the key figures and characteristics. DataSources with this delta type can write to ODS objects or master data tables.
Check also examples in "How to... Create Generic Delta" under www.service.sap.com/bi.

Doubt in Generic data sources for hierarchy & text

Hi All,
I have a couple of doubts as mentioned below.
1 . Why we canu2019t generate generic data source for hierarchy?
2. While creating Generic datasource for text there is one more option is available i.e. "Extraction from domain"
what is domian please explain .
Thanks & Regards,
Saurabh Bansal

Hi,
1.We can't maintain Hierarchies in ECC, Because the Database design of the OLTP system is based on ERM(Entity Relationship Model),i.e Tables are connected via Primary and Foriegn key relationships, Whenever we need 1: Many connection divide the data in different tables,connect them using the primary and foriegn key relationships.
2. Domain will provide the technical properties of the Field of the R/3 table.
for Eg: length,data type of the field.

Doubt about generic method

i have a generic method has shown below
public static <E extends Number> <E>process(E list){
List<Interger> output = new ArrayList<Interger>(); or List<Number> output = new ArrayList<Number>();
return output ;
if delcare the output variable using Interger or Number . when i am returning the output . it is showing me compiler error and it suggests me to add cast List<E>. Why i not able understand. please clarify my doubt.
Thanks

Your method declaration is garbled; there can be only one <...> clause, eg
public static <E extends Number> E process(E list);This declaration says that for any subclass E of Number, the method process takes a single E instance (called list!?) and returns a single E instance. A valid implementation would be
return list;I'm guessing you want the parameter to have type List<E>?. Like this:
public static <E extends Number> E process(List<E> list);This declaration says that for any subclass E of Number, the method process takes a list of E's and returns a single E instance. A valid implementation would be
return list.get(0);Or perhaps you also want to return a list of numbers?
public static <E extends Number> List<E> process(List<E> list);This declaration says that for any subclass E of Number, the method process takes a list of E's and returns another list of E's. A valid implementation would be
return list;Note that you cannot just return a list of Integers or Floats, because your generic method must work for any subclass of Number, and you're promising to return back a list of the same type as the argument passed in.

Doubts with generic service in "HCM processes and forms"

Hello friends:
    Im having troubles trying to figure out how to use generic services. I implemented a badi with generic services and this have the following methods:
IF_HRASR00GEN_SERVICE~GET_SPECIAL_FIELDS
IF_HRASR00GEN_SERVICE~GET_FIELD_INFO
IF_HRASR00GEN_SERVICE~GET_OPERATIONS
IF_HRASR00GEN_SERVICE~INITIALIZE
IF_HRASR00GEN_SERVICE~DO_OPERATIONS
IF_HRASR00GEN_SERVICE~GET_HELP_VALUES
   I could initialize values of my form using only INITIALIZE method, and I could perform some validation using and then DO_OPERATIONS.
   I cant understand what is the usage of methods like GET_FIELD_INFO and GET_OPERATIONS?? according to the badis help, get_field_info must be implemented, but i didnt do so and it worked anyway?
I will be grateful with all your help,
Best regards,

GET_FIELD_INFO is for adding fields. Suppose you are using the generic service for IT0008 data. The IT0008 fields
which need to be used on the adobe form has to be added in this method. You need to add field name and data element
to the field_infos table. GET_OPERATIONS is used to define operations associated with the fields. Suppose you have a
scenario when user selects personnel area all personnel subareas associated with the selected value should come.
Then you need to group together personnel area and sub area together into an operation. Also even if a field is not aasociated
with any operation, to add a field to form scenario you need group them into operations in GET_OPERATIONS.
Check the class CL_IM_HRRCF_REQUI_REQUEST to determine how this can be used.
Thanks,
Aravind

              r_date-high = '9991231'.
            ENDIF.
            APPEND r_date.
        ENDCASE.
      ENDLOOP.

Doubt regarding Generic methods

Hi Ben,
Thanks for your replay, Can you please tell me why in first case ie getEJBHome method call findEJBHomeAndPopulateCache(jndiName,ejbHomeClass) not causing any error.In both case upper bound of T is EJBLocalHome .Kindly give me a clear idea.

Doubt in Generic Servlet and Http Servlet

Hi,
I studied Genaric Servlet does not support state and session mengement and where as Http Servlet supports state and session mengement.
Why Genaric Servlet does not support state and session mengement ?
Can any one plz tell me reasons.

GenericServlet is pretty much the most basic Java application that you can run server-side. It doesn't support much of anything except for the basic life cycle management and a couple other things. Go to Dictionary.com and lookup the word Generic. It's used a lot in software development. Go to http://java.sun.com/j2ee/1.4/docs/api/index.html to read more on the GenericServlet class.
BalusC, because a thread hasn't been active in awhile doesn't mean it's dead. If it were dead it would not be editable. Moreover, the question was never answered (adequately).

Generic DataSource using FM - Delta doubt

Hi All,
I have few doubts on Generic DataSource Delta.
I am working on one HR requirement. where I need to pull the Mandatory courses information.
to get this done, we have created one Generic DataSource using Function Module.
FM has huge and complex logic, at present it is taking long time when I run in RSA3, if I continue with this to BI, daily running FULL load to BI is not suggestible, because it takes much time to load.
I have planned to set the Delta, just want to know what would be the best option to set the delta option for this requirement? and how? I have 2 dates (Course Start and End dates), Employee, Course Id, Course Type, Position, Job, etc in my DS structure.
Please suggest someone so that I can do FULL load once in BI and continue with Delta without missing any delta records going forward.
Regards,
Kiran

Hi,
In mystrucure used dates are not relating to aedat and erdat, they are CHAR type. here the requirement is little different.

Regards Generic Delta

Hi Guys,
I have a small doubt regarding Generic Delta Extraction. In Generic Delta i choose Calday on Posting Date. And am getting data on Daily basis. Here My doubt is can I use this posting date in field selection in Info package. If not?Please give me clarification regarding the same.
Thanks,
Tg.

Hi Tg,
If I have understood correctly, Posting date has been chosen as the delta field in datasource.
I don't think you can use the fiield in infopackage selection because the field is used to extract delta for that generic datasource and the system doesn't allow us to put a filter on the filed which is responsible for delta .
If system wud have allowed us to put a selection on that field then correct delta will not be loaded in BI.
System can not allow us to play with deltas and hence the field is not avaialble for selection .
Hope it helps,
Manish Sharma

I will allocate points for all satisfactory answers.

Hi,
If you want to extract few fields from VBAK and few fields from VBEP, in such case you have to go for generic extraction. and if you want to extract data using FMs and from iViews you have to go for generic extraction.

Generic datasource based on custom table and hierarchy table

Hi Gurus,
I have a doubt regarding generic datasource.
my requirement: to create a datasource with 10 fields. (7 fields from custom table and 3 fields whose values can be derived from a hierarchy table).
I have a custom table. In this table one field refers to a hierarchy table. Using this hierarchy table, we can derive values to 3 new fields.
My question is, If i create a generic datasource based on the custom table, how can i include the extra 3 fields which gets values from the hierarchy table.
Where can i write the logic to extract the values for those 3 fields from the hierarchy table.
Thanks

Regarding genric data source

hi guyz,
     i have some doubts regarding generic data source for the following qeastion.
   1).what is ALE pointer(ALE delta)?.in which senario we use this?.can u explain me with one realtime senario so that i can understand easily.
   2).what is SLA? explain with one senario.
   3).when we use these t-codes: RSMO,SM50 in process chain.

1. ALE is Application Link Enabling (ALE)
It is the set of tools, programs, and data definitions that provides the mechanism for distributing SAP functionality and data across multiple systems. ALE enables the construction and operation of distributed applications.
Its purpose was to overcome the limitations of a single SAP system. A single SAP system that runs on top of one database often does not fulfill the needs of larger corporations, either from a business or a technical perspective.ALE allows the implementation of loosely coupled SAP systems; each of the SAP systems has its own database and is essentially independent from the other systems. ALE allows us to distribute data between different systems and different business processes.
ALE enables you to transfer data(master/transactional data) from an SAP system to SAP/Non-SAP system you can use ALE.This done using IDOCs.
ALE can be divided into
Output Process: Extracting data from database and putting it in the IDOC.
Communication Process: Which involves transferring the IDOC to the target system.
Inbound Process: Posting the IDOC data into the tables of the receiver system.
2. SLA is service level agreement, what you need on this ?? Its an agreement betn client and service provider regarding the service request and their resolution. Like P! issue should be solved in 1 hr , P2 issue 3 hr..something like that, varies from client to client
3. RSMO is used to monitor the data load in BW. You have several options to restrict your criteria to monitor load.
In SM37 if you goto the job and double click on that, it brings you to another screen with some details for the job. IN this screen if you hit the job details button in the resulting screen, it'll show you a PID number and an executing server number. With this combination, you can check the job in SM50.
Assign Points if helpfull.
Thanks
