Datasource 2LIS_03_BF (Goods Movements From Inventory Management) Extraction Logic

Hi Experts,

Any idea what is the logic behind DataSource 2LIS_03_BF Extraction logic ?

My Delta records are not matching with table records.

Data is picked from MSEG, MBEW and MKPF. But I want to know on which logic, it is extracting records and where it is written.

Quick help will be appreciated.

Thanks in Advance,

Manoj
