We have been trying to extend the existing AUto-ID 4.0 SP5 BW reporting to include additional data elements we are capturing with the observational transactions. SAP provides some method and BADI (MODIFY_BW_EXTRACT_STRUCTURE) but limited documentation on how to code it. We have already added the necessary data elements and they are working correctly (we see them in the UI, and we have created the necessary BW append strucute). What my developers tell me they need is the underlying tables to which the elements are added. Also, any example of this being done to extend appended data fields to AII transaction data would likely show us what we need. We need help finding the AII transaction data and where the tables are so that the proper code can be added. SAP has implemented an untypical approach here, and its likely due to the need to improve performance of extracting the large amounts of RFID data.
If anyone can assist, we are at critical milestone in our project and would welcome the input. If you need to forward this request to anyone, please do.
