I am trying to update an internal which is within another table.Its actually a deep structure but when i try to update it its giving me a short dump.
Below is my code
*declaration of variables
DATA: it_levy TYPE LB_T_BIL_IT_KOND,
wa_levy LIKE LINE OF it_levy.
*reading the data from the internal table to my work area
READ TABLE IS_BIL_INVOICE-IT_KOND INTO wa_levy
WITH KEY BIL_NUMBER = GS_IT_GEN-BIL_NUMBER
ITM_NUMBER = GS_IT_GEN-ITM_NUMBER
KSCHL = 'ZWNT' BINARY SEARCH.
*Update certain fields and update the final internal table
IF wa_levy-KSCHL = 'ZWNT'.
wa_levy-ITM_NUMBER = '000011'.
wa_levy-KPOSN = '000011'.
MODIFY IS_BIL_INVOICE-IT_KOND FROM wa_levy. *I'm getting a short-dump here
I have also attached a screen short of the short dump
