SAP ABAP Problems & Solution

Initial & Not initial: In SAP we use initial & not initial  keyword for internal table value check purpose. Initial means there is no records in the internal table. Like we  have an internal table as IT_Doc. so we use initial keyword as:    if IT_doc is initial. Give message " no record found". endif.   Not initial:  At least one record is in there.   for similar internal table we can write :   If IT_Doc is not initial.   "then set logic to display the value".   endif.
