Diff between the Start routine and Update rules?

Hi Gurus
Diff between the Start routine and Update rules?
Thanks in advance
Raj

Hi,
Routines are like conditions or business rules that could be applied to filter the data while entering the BW system or could be used to apply certain conditions on the info objects itself.Update rule level you manipulate your data and write your start routine.
There are 4 types of routines
1. Start routine- Could be used at two levels (transfer rule level and the Update rule level)
This Start routine written at the transfer rule level helps filter the necessary data coming from the source system.
For Example: If you decide to extract data that contain only quantity greater than 500 , then you could specify the Start rouitne to achieve this.
The Start routine at the Update rule level provides similar functionality but at this point it helps direct specific data to
different data targets. For Example: If there 3 data targets being fed from the Infosource, you may want to apply some condition to each data target, like send year 2000 data ti Data target1, 2001 to data target 2 and so on. This can be achieved by using Start routine at the Update rule level
2. Transfer Routine: This feature is available at the transfer rule levels
While performing the transfer rules operation, there are 4 features available to the developers to create business rules on top pf the Infoobjects.
1. You could do a one to one mappping of the Infoobject
2. Provide a constant value
3. Include a formula
4. Write an ABAP routine.
These 4 options refers to the transfer routine
3. Update Routine:
The limitations of just having 4 options in the transfer routine is overcome at the update rule level. There are various other
sophisticated features avaialable apart from the 4 options mentioned above. These business rules could be specified pertaining to each data target.
4. Conversion Routine: It provides functionality to do Currency and unit conversion.

Start routine and update rules

Hi,
What is accessed first:-
Start Routines or Update Rules?
What is the use of global variables in start routine?
Please reply.
Thanks.

Hi......
You have different types of Routines in BW .
1) Start Routine in Transfer Rules
2) Transfer Routine in Transfer Rules.
3)Start Routine in Update Rules
4)Update Routine in Update Rules.
The routines that you write in transfer rules are applicable to all the Data targets that get the data from that particular Infosource, when you are going to write some code in Transfer rules, you have to understand that you are going to manupilate the data that is going to get into BW .
If you are going to write in Update Rules , then that logic is going to apply only for that particular Data target .
Eg : Let suppose I have a Flat file that gets data from 3 countries, US, Canada and Mexico.
Now I have prepared the data source for the same . But I dont want to have the data of Mexico in to BW itself.
So I will write a Start routine at TR to eliminate the data of Mexico.
My Next step is I want the data of US into one ODS and Canada data in to another ODS.
For this I handle the dataflow at Start routine in Update rules, to eliminate Canada data for US ODS and Vice Versa.
Global variables in Start routine
You can have global variables, internal tables populated by the
startup routine. This data will be available to the field
routines. Create yourself a start routine, declare some
variables in the global section, and then create a field
routine. You will be able to use the globally declared objects
in the field routine

Deleting rows with missing values in field in start routine of update rule

Hello experts,
how can I delet rows with missing values in a specific field in the start routine of update rules?
I think ABAP code should look something like this:
delete ... from DATA_PACKAGE where Z_NO = ''.
thanks in advance for any suggestions!
hiza

Write:
delete data_package where field = value.
Hope it helps.

ABAP Help at start routine of Update rule

Good After Noon All,
My requirement is that cube ZAPO_C24M theres an UPDR flowing from 8ZAPO_C24M back to itself so to speak.The request is to change the data in the cube from Fiscal Year Variant Z3 to Z4.
But in start routine i have to take the existing record and reverse all of the key figures, and also change the RECORDMODE of the record to indicate it is a reversal record. This for specific Country KR and for these country the Fiscal variant is Z3. Again in the start routine, create a new record identical to the existing record that has Fiscal Year Variant Z4 instead of Z3.
So the idea is wed load from the cube and send back to the cube one record that reverses out the existing data, and another record that contains the same data but with Fiscal Variant Z4 instead of Z3.
Please Help me.
Points will be awarded for the right answer

Hi Vaishali,
In the start routine copy the DATA_PACKAGE to a local table.
Select the records where the specific country is KR.
Delete all other records.
Then read the records in loop, Keep one record same and just change the fiscal year variant.
And for the same multiply all the key figures by -1.
Transfer the content of the local table back to DATA_PACKAGE.
maintain one to one mapping in the update rule.
I am sure it will update, but you need to be sure that if you change Fiscal year variant then probably your fiscal period value should change. In that case you have to update it accordingly in the start routine.
Regards.

Help needed on start routines in update rules

Hi All,
I want to extract data from two data sources(For ex 2LIS_02_HDR, 2LIS_02_ITM).
I am using 2 first layer ODS' and one second layer ODS for consolidation.I want to write a start routine in the update rules so that the data of the MATNR(Material Number) field from 2LIS_02_ITM will be populated in the second layer ODS when the keys (EBELN) of the datasources are equal in the first layer ODS'.
Can anyone send me the code for this requirement?
Thanks in Advance,
Sanjana.

i am assuming u have a direct transformation with 2lis_02_hdr
and u want to look up on the DSO of 2lis_02_ITM to get the material.
MATNR = 0material
EBELN = 0docnum.
put this code in the start routine of the transformation of 2lis_02_HDR.
TYPES: BEGIN OF s_itm,
            material TYPE /bi0/oimaterial,
            docnum TYPE /bi0/oidocnum,
            END OF s_itm.
    DATA: wa_itm TYPE s_itm,
          t_itm TYPE STANDARD TABLE OF s_itm.
LOOP AT DATA_PACKAGE.
        SELECT material
                      docnum
        FROM /bic/aDSO_itm
   APPENDING TABLE t_itm
   WHERE docnum = <comm_structure>-docnum.
endloop.
IF NOT t_itm[] IS INITIAL.
      SORT t_itm ASCENDING BY docnum.
     DELETE ADJACENT DUPLICATES FROM t_itm      COMPARING docnum.
     ENDIF.
Now write this below code in the update routine of 0material in the transformation from 2lis_2_HDR.
CLEAR RESULT.
READ TABLE T_itm INTO WA_Itm WITH KEY
      DOCNUM = comm_structure-docnum.
BINARY SEARCH.
IF SY-SUBRC = 0.
RESULT = WA_itm-material.
ENDIF.

Start Routine or Update Rule Routine

Hello Dear Friends
I have a requirement here to create an object lets call it TYPE and i am using another infoobject called movement type.
My requirement in the cube is that TYPE should indicate A if movment type is 123 or 456 and B if movment type is 789.Anything else other than these numbers dont need to make it in the cube either for Movement type or for TYPE and needs to be deleted.I believe this will be a routine in the Start Routine.If not please let me know.Also if someone can give me the code on how to write the routine will be really appreciated.
Thanks again.

hi,
Go for an Update routine as you do not have the TYPE in the Data source.
if ( comm_structure-momenttype = '123' or
   comm_structure-momenttype = '456' ).
comm_structure-type = 'A'.
elseif comm_structure-momenttype = '789' .
comm_structure-type = 'B'.
endif.
Adn in the start routine :
delete data_package where momenttype ne '123' and
                                         momenttype ne '456' and
                                         momenttype ne '789' .
If you can add the type in the data source then write the below code.
delete data_package where momenttype ne '123' and
                                         momenttype ne '456' and
                                         momenttype ne '789' .
loop at data_package.
if ( data_package-momenttype = '123' or
   data_package-momenttype = '456' ).
data_package-type = 'A'.
elseif data_package-momenttype = '789' .
data_package-type = 'B'.
endif.
modify data_package.
endloop.
good luck

How to debug start routines of update rules from ODS to InfoCube

Dear gurus,
I have an update rule from ODS to InfoCube. I wrote a start routine in the update rule. Now I want to debug it. I went to monitor and simulate update the data package and only got the prompt "No data exists in the corresponding PSA table". So how can I debug this start routine?
Thanks in advance.
Jin Ming

Jin,
In order to use PSA between ODS and InfoCube, you may have to use an exclusive InfoPackage and load separately. In that InfoPackage, choose the radio button to use a PSA.
I think you are currently updating the InfoCube directly without using a separate InfoPackage.
Look for an InfoSource under DataMarts (search for 8<ODS Technical name>) and create your InfoPackage there.
Good luck.

Process: Start Routine, Delta, Update Rules

Hi SDN,
Can someone point to detailed discussion on the events related to loading, such as:
Start Routine is exectued before each data package, or entire load?
Update rules are applied row by row or the entire KYF column in a data package is processed first?
When is delta determined, before Start Routine is executed, or, after it is executed, and before update rules are applied? This is important to know if we are dropping records from the data package.
If you have the answers, would love to hear and appreciate.
Thanks.
Saf.
P.S. I always award points.

Thanks Farhan,
If you don't mind, can you outline how delta is determined, between ODS and ODS and ODS and Infocube. If I am correct, records in the sender object are marked as sent. Can I look at the field where the flag is?
Also, you are saying that only those records make up the data package which are new, in case of a delta load. That means, if there were no new records, Start Routine would not even execute, or it still will but do not have any records processed?
I already awarded the points.
Thanks.
Saf.

Start Routine in Update Rule

I want to replace all '# ' values showing up in a report with space. For this I plan to write a Start Routine in the Update Rules which should scan all the data coming in into the cube and replace all null or '' with space.
What is the best way to write this routine. It should check all data in all the fields of the data load coming in.
Thanks

Hi,
     The space is shown as # in the BW Reports, to confirm check the value in the cube for this field, so
      you need to change that to some other character like X or Y or explain your end users that SAP
      designates a space as # and it will be displayed that way in the reports.

Raj

Start routine for Update Rules

I need to write a start routine for the update rules for an DSO with main idea as follows:
I must compare the record that comes from the infopackage with the record that's already in my DSO. If the X date for the same 0PM_ORDER is the same as one in my DSO - do nothing
If the X date is previous to the X date in my DSO for the same 0PM_ORDER - the new record must be created and at the same time all the records with subsequent(later) X dates for this 0PM_ORDER must be deleted.
If the X date is later than the X date in my DSO for the same 0PM_ORDER - the new record must be created.

Hi,
Find the below code.
DATA: BEGIN OF ITAB1,
ZDATE TYPE /BIC/DATE
END OF ITAB1.
SELECT zdate FROM /BI0/QEMPLOYEE INTO corresponding
fields
of ITAB1 where employee = SOURCE_FIELDS-EMPLOYEE.
IF ITAB1-ZDATE COMMUNICATE_STRUCT-DATE
RESULT = ITAB1-CLM_IPAA.
ENDIF.
ENDSELECT.
There will be an table for each DSO if you go for an manage DSO you will get three table i.e New,Active and Change Log take Active tables date field and compare with the communication structure that comes to routine.
The above example is just an example table will be different from DSO to DSO.
Let me know your thoghts.

Shivu.

Start routine at update rules.

Hi all,
I am working with Sales schedule line data.
Data flow is R/3 -
DSO----CUbe.
I have to load all the data for all sales organizations till DSO.
From DSO to CUbe I have to load the data only for 4 sales organizations.
I am planning to write Start routine in the update rules.
Could any body Please help me with code..
REgards,
MAdhu

Place this code in your start routine:
*remove sales organization, assume this is a standard infoobject
this deletes all data except for the 4 sales orgs
DELETE DATA_PACKAGE WHERE NOT ( /BI0/0SALES_ORG = 1 OR
                                                               /BI0/0SALES_ORG = 2 OR
                                                               /BI0/SALES_ORG = 3 OR
                                                               /BI0/SALES_ORG = 4 ) .
Also put restrictions in your infopackage, even though its redundant.

COLLECT statement in start routine of update rules for data coming from R/3

Hi,
I have more than one record with the same key combination that comes from R/3. I have a condition wherein I write into an error log. Hence I want only ione entry to be written into a error log and not multiple instances.
I had written a similar one for ODS.
Loop at IT_ODS into WA_ODS.
Collect WA_ODS into IT_SUM.
How to collect data that is coming in from R/3. Any inputs?

Hi,
I think, by using ATEND you can acheive control break logic.

Debugging: start routine in transfer rules

Hi !
can you please tell me how to debug start routines and field routines in transfer rules?
If possible please tell me too debugging of update rules.

Hi Rajib,
Go to the monitor -> Details tab -> Processing -> Choose the datapackage you want to debug -> Right click -> Simulate update -> Choose eather activate debugging in transfer rules (to debug in transfer rules) or debugging in update rules(for start routine and update rules).
You can mention the number records you want to debug also, if you have an idea of which records you want to debug you can give the number of that record.
Once the debug screen comes up, press F8...the control stops at first break point...from there you can do a step by step debugging (F5).
Hope this helps...

Kalyan

Is difference between update routine,start routine and transfer routine

Hi All,
What is difference between transfer routine and update routine.

Hi Venkat,
Routine is a set of ABAP code which is used to select a record or transform the field value at the time of loading the data.
Types of routines:
Tranfer Routines in Transfer Rules:
Start Routines in Transfer Rules:
Update Routines in Update Rules:
Start Routines in Update Rules:
Transfer/Update routine:
It's the set of ABAP code used in Transfer/Update rules. Transfer/Update routine is used to change the value of a particular field/object at the time of loading data.
Ex: Populate the amount/discount field by using Price and Quantity based on the given conditions.
Start Routine:
Start routine can be used in both Transfer Rules and Update Rules. Start routine is used to determine whether to load a particular record or not.
Ex: From the data related to the year 2005, we can select only the records which belong to a particular month or fiscal period.
Ultimately Transfer/Update routines are to update the value of a particular field. Start routines are used to select entire record.
