Hi need help in data extraction.

Question

Hi everybody,
       I am trying to extract some ekpo table datas from R/3 and load in BW. What i did was:
1) created a char info object with a field and no attributes.
2) Created a Key fig with Target quantity-->0unit.
3) Created Info cube Assigned Dimensions.
4) Created a info source with all the three fields(Ebeln, 0unit, tar_quan).
5) Now I open R/3, t-code SBIW --> generic data source
--> created new transaction data name ---> gave an appli comp.
6) In the Column view/Table(text box) I gave as EKPO , to extract data from table EKPO. When I saved, it gives this error message.       
"Invalid extract structure template EKPO of DataSource" .
What should i do to extract the datas from EKPO from R/3 to BW.
Please, help me with this.

Hi Naga
Do not create a view or what ever for what you want to extract. I mean You ask : "What should i do to extract the datas from EKPO from R/3 to BW"
the answer is activate the standard Datasource for purchasing that allows you to extract data from table ekpo.
The datasource name is 2LIS_02_ITM
activate it in r3 with TC RSA5 have a look in RSA6 before to check if it is already avalaible (if not then proceed with RSA5)
Then go to the LO cockpit TC LBWE find your datasource in application 02 and look if it is active, if not do it. With the maintenance screen you can select your fields.
If you want to extract data from R3 what you should do before creating view FM and so on is to check if business content datasource exists first.
For Example you do not have a standard datasource for purchase requisition from eban and ebkn, so it is logical for you to create a generic ds based on tables FM and struc. etc... but SAP provide you with standard datasources so make use of it when they exist. You find names and info on existing datasources etc on SDN, help.sap.com sap.service for example.
hope this helps
