I've had a dump recently,
DATA: gt_data TYPE SORTED TABLE OF ty_data WITH NON-UNIQUE KEY bukrs gaapnm,
lt_tabdel TYPE standard TABLE OF ty_data.
LOOP AT gt_data ASSIGNING <gf_data>.
IF <gf_data>-KANSW + <gf_data>-KAUFW = 0.
APPEND <gf_data> TO lt_tabdel.
IF lt_tabdel IS NOT INITIAL.
DELETE gt_data FROM lt_tabdel.
And on the line with deleting table from internal table - i've had a dump: In statement
Convert object to integer
only numerical type data objects are supported at argument position
In the present case, operand "object" has the non-numerical data type "TABLE
OF TY_DATA". I just can't understand - why? Both of it had the same type... So, it will be great if you could provide some advice and a bit of explanation of error origins.
