Base tables for datasource which is based on function module?

[Former Member]

Hi all,

I came through the data source which is based on function module. I want to find a base table for that particular data source. There is a extractor field in RSA2 in which there is whole routine. I went through the whole routine but was not able to find the base tables from which different fields are extracted?    

So, please suggest how to find all base tables from which fields have been extracted or is there any other method to get the base tables for data source based on function module???

I am not looking at LO extractor. It is a ordinary DS. I have to find the base table from coding of FM. But not able to get the base tables as i am new to SAP. There were many tables in the code but none of them is having any field from which data is being extracted. I also looked into the SELECT statement to find the table but none of the table are having those fields.

Thanks

In your FM coding look for statement 'OPEN CURSOR' the table mentioned in this statement should be the base table for selection and then the rest of the tables must be the helping tables used for validation and populating some of the other fields of the datasource.

Also you can post your code of FM then we can look at it and tell you the base tables.

Thanks
