SAP LIS extractor vs creating custom extractors

Dear Experts,

I am trying to evaluate Pros and Cons in scenario of creating a custom extractors instead of using relevant LIS extractors. Its a greenfield Implementation.

One of the reason why we plan to do so is to avoid down time due to setup table filling in case of future enhancements needed for standard extractors. So wanted to understand approach needed for setting up equivalent delta pointers for custom extractors and also consider benefits of using standard LIS extractors vs equivalent custom extractors for SD and MM BW reporting.

Many thanks.

    My experience is the LIS extractors do all the heavy lifting, and I haven't had to make any changes to them. They work "out of the box"

    CDS based new extractors are on the way. PM is already delivered and some more are available for cloud. However, the time plan is not shared.

    You're totally right about your concern. Considering the effort you'll need for development and possible problems you may face; it's all up to your call :)

    LIS extractors manage the delta for you.

    Recreating that functionality would be difficult and expensive.

    As to your point about enhancements - If you wanted to enhance your custom extractor after deployment, wouldn't you have to drop and reload the data anyway?

    Many times, enhancing LIS extractor in the source issues can be side stepped by adding or enhancing master data master data attributes for Document numbers and data modeling onnthe BW side - just as you might do for a custom solution.
