How to enhance Standard Extractor for 0CUSTOMER_ATTR

Question

Hi,
I need to enhance the standard extractor of 0CUSTOMER_ATTR in order to populate the newly added attributes.
I have few questions:-
1) Will there be any impact of manually adding attributes to 0CUSTOMER on the data flow/where used list of 0CUSTOMER.
2) In order to get the master data for newly added attributes we will need to enhance the extractor. Could you let me know the entire process of enhancing the standard extractor.
3) Will it be safe to make a copy of 0CUSTOMER as ZCUSTOMER, add the new attributes in ZCUSTOMER and use ZCUSTOMER for our requirement. In this case also we will need to enhance the extractor.
Your inputs will be helpful.
Thanks,
Naveen Kr. Choudhary

1) Will there be any impact of manually adding attributes to 0CUSTOMER on the data flow/where used list of 0CUSTOMER.
No there will not be any impact for the where used list of 0CUSTOMER info object, there will be effect once the enhanced data source is replicated to BI side.
2) In order to get the master data for newly added attributes we will need to enhance the extractor. Could you let me know the entire process of enhancing the standard extractor.
SE11 --> create the Structure
Tcode: RSA6 -> Double click on the Data source --> Now in the DS:customer version screen you can see the extract structure name --> double click on it -->Next you will find an option of Append Structure button --> click on it -->
Add the necessary field's in the Append Structure with Component Type:. Before you exit, make sure that you activate the
structure by clicking on the activate button.
Next
-->You need to confirm that the Added filed has been added to the DataSource and that it will be available to BW. When you go  back at the Postprocess Datasource and Hierarchy screen(RSA6), select the same DataSource again and press the Change DataSource button .
Check for the filed that you had appended, it will be appeared at the bottom of the extract structure.
Once this is done now the appended fileds are ready in DS, now we need to populate the data from the corresponding tables.
For this Select the Data source 0customer_attr --> click on Function enhancement --> enter the project name and next enter the Enhancement RSAP0002 This enhancement has four components that are specific to each of the four types of R/3
DataSources:
Transaction data EXIT_SAPLRSAP_001
Master data attributes EXIT_SAPLRSAP_002
Master data texts EXIT_SAPLRSAP_003
Master data hierarchies EXIT_SAPLRSAP_004
With these four components , any R/3 DataSource can be enhanced suing the above 4 Function module. In this case, you are enhancing a Master data DataSource, so you only need EXIT_SAPLRSAP_002 .
Next we need ABAP developer in order to enahance the DS and write the logic to populate the values to the filed from the source table.
once this is done save the code and activate it.
Next fill the set up tables and  Goto RSA3 tcode check the data source and check for the fileds that were appened are populated with the values or not.
(for more detailed steps our friend Chowdary has send u the links go through them)
3) Will it be safe to make a copy of 0CUSTOMER as ZCUSTOMER, add the new attributes in ZCUSTOMER and use ZCUSTOMER for our requirement. In this case also we will need to enhance the extractor.
I dont think there is a need for creating a new ZCUSTOMER , you can use the standard one.
