sap - Type conflict within deleting table from internal table -


i've had dump recently, 

data: gt_data    type sorted table of ty_data non-unique key bukrs gaapnm,      ...      lt_tabdel  type standard table of ty_data.    loop @ gt_data assigning <gf_data>.     if <gf_data>-kansw + <gf_data>-kaufw = 0.       append <gf_data> lt_tabdel.     endif.   endloop.    if lt_tabdel not initial.     delete gt_data lt_tabdel.   endif.

and on line deleting table internal table - i've had dump: in statement convert object integer numerical type data objects supported @ argument position "object". in present case, operand "object" has non-numerical data type "table of ty_data". can't understand - why? both of had same type... so, great if provide advice , bit of explanation of error origins.

you have (inadvertently) used this variant of delete statement uses from , to specify indexes, i. e. numbers of table lines. in sense, coding delete lines in gt_data below 1 identified line number in lt_tabdel, , system goes belly-up when trying convert contents of lt_tabdel integer.

as far can see - i. e. if you've provided complete code sample - should sufficient:

loop @ gt_data assigning <gf_data>.   if <gf_data>-kansw + <gf_data>-kaufw = 0.     delete gt_data.     continue. " safety measure   endif. endloop.

for explanation of continue statement, check this answer.
