short dump when we enter wrong ibase number in service order

Hi All,

I am getting short dump when i enter wrong Ibase number in service order and cliclk enter . but when the ibase filed is black and currect ibase number is entered in the filed and click enter No Dump.

I tried to debug,  it is going to standard ORDER_MAINTAIN functional module.  there is dump  Assert Condition was  Voilated.

my observation  : for blank   ibase , at this function module i found one entry  ct_orderadm_h table but for the wrong Ibase number the table has no entries.

For standard filed , the system should take care of it right?  why its dump on wrong Ibase number .

Regards,
