Function Module Extraction from KONV Table taking lot of time for extractio
Hi
I have a requirement wherein i need to get records from KONV Table (Conditions (Transaction Data) ). i need the data corresponding to Application (KAPPL) = 'F'.
For this i had written one function module but it is taking lot of time (@ 2.5 hrs) for fetching records as there are large number of records in KONV Table.
I am pasting the Function Module code for reference.
<b>kindly guide me as to how the extraction performance can be improved.</b>
<b>Function Module Code:</b>
FUNCTION ZBW_SHPMNT_COND.
