Defining Custom Extractor

[Former Member]

Hi experts,

Can someone guide me with best practices for creating Generic Datasource with Custom extractors(FM)?

Is there any document available for the steps involved in setting up the custom function module(extractor) for GE(Generic datasource)?

Thank you

Hi,

Let me put it this way.

I want to copy the Business content datasource and its extractor for e.g 0CO_OM_OPA_1 to custom datasource and make some more complex coding.

What is process involved in Copying the FM and using it in the new datasource created?

Is there document explaining the step by step process of copying the datasource with FM? Because it seems like there should be an entry for datasource and FM in ROIS as well as in several tables in R3?

Thanks in advance

Hi,

if you are using stand business content datasource then yo are better writing the user exit to populate the enhance structure than copying the function module and all your complex calculations can be taken care of in the user exit.

for more info i have a thread regarding mclips and there step by step has been explained

hope that helps

thanks

Hi Elena Ganchenko,

I know this FM RSAX_BIW_GET_DATA_SIMPLE already.

Basically i am looking for a document which explains the step involved in setting up the custom extractos with Function module and linking it with the datasource? How the actual connection between the Datasource and FM(Extractor) is made?

Thanks in advance

Hi Arun,

Unfortunately I don't have detail description of parameters and structures used in this template.

To create

1. Generic Datasourse you should go to transaction RSO2(SBIW>Generic Datasources>Maintain Generic Datasources) 2. enter the name and click create

3. then system asks you to enter all the necessary information

Appl component, texts and extraction method with parameters.

To use FM as extractor click on "Extraction by FM" and enter FM and extract structure in the corresponding fields.

Good Luck!

Hi Arun,

see function module template RSAX_BIW_GET_DATA_SIMPLE.

It is mentioned in BW350 course book.

Also you can user table/view and sap query.

Good Luck,
