writing custom code for enhancing the generic data source

[Former Member]

Hi,

I need to create a generic extractor from two main tables ( Header and detail) by creating the extractor based on a view of these two tables. However I also need to include information/fields ( both header as well as detail level) form a host of ther tables in the data source.

I would like to know where to find the the extractor program and/or user exit to write the custom code for populating the fields, after appending additional fields the append structure manually.

Also want to know whether the entire data source extended this way should be delta enabled?

If there are other ways to do this, example function module etc.. I would like to know.

Thanks in advance for the help and I would reward with appropriate points

Hi dear,

about delta enabling of your datasource, you have to activate it on RSO2 (as "generic delta": you can find a lot of useful info in previous posts about this topic!).

About enhancement to fill additional fields, you have to follow the same procedure as per standard datasource: after adding them into an append, you have to use CMOD and include RSAP0001 enhancement and userexit EXIT_SAPLRSAP_001 for transactional data...(you can find a lot of info for this topic too!)

Hope it helps!

Bye,
