Need "Generic Data source using Function module" to handle Delta
I have used the function module RSAX_BIW_GET_DATA_SIMPLE and copied to write a generic data extractor to suit my requirement, its working fine in and I have been able to successfully load data into BW system form the source system using this data source.
I would now like to make it delta enabled, my main table (from where the FM extractor gets the data) has two (actually four) fields. Create date and Time, Change Date and Time is available.
Can any body suggest as how do I make this data extraction delta enabled (either by Time stamp or delta queue or anything else)?
For your information the start table is CMSD_LO_HEADER. Do we have any existing data source form SAP for this.
