Nested internal table

Saha_Arpan — Tue, 10 Jan 2012 20:14:16 GMT

Hi Sap gurus,

Am in a bit of a fix right now..............

I have got an internal table in the format - Doknr and a nested table.....such that for every doknr multiple records may exist in the nested table.............

it is if the format:::: begin of ty_nested, doknr type doknr, include structure zstruct, types: end of ty_nested.

now i want to append data into this particular table so that whenever a particuar doknr comes up all the corresponding data fro the doknr should go into the nested table

it should be of the format........ doknr->nestedtable. '/' denotes the multiple records that exist in the nested table

10 2/3/4

20 1/3

30 3/4/5

any help will be appreciated......

if this a nested table? including a structure just adds the fields from the structure. right? so along with docnr you have other fields from zstruct. its not making it a nested table

sorry i forgot to add that the zstuct is actually a dictionary table type................so in other words it is a nested internal table

have you done CTRL+F2 on your program, isnt it showing error?

your syntax should be

include type <a table type name>

not include structure <a table type name>

ok lets check your query now

try this code. i have kept it simple... try to understand. execute this. its will trigger a break point. then check the content of TB

types: begin OF testy,
           system type BAPILOGSYS,
           include type  BAPIRET2_T."ZVBAk.
types: end of testy.

DATA: ts type testy,
      tb type TABLE OF testy,
      wa type BAPIRET2,
      wt type BAPIRET2_t,
      wt2 type BAPIRET2_t,
      pt type TABLE OF bapilogsys,
      ps like LINE OF pt.
*lets have to systems
append '1ST_SYSTEM' to pt.
append '2ND_SYSTEM' to pt.
*-- lets have data for bapiret2_t table with 2 systems
wa-MESSAGE = '1st one, for 1st system'.
wa-system = '1ST_SYSTEM'.
APPEND wa to wt.
wa-MESSAGE = '2nt one, for 1st system'.
wa-system = '1ST_SYSTEM'.
APPEND wa to wt.
wa-MESSAGE = '3rd one, for 2nd system'.
wa-system = '2ND_SYSTEM'.
APPEND wa to wt.
wa-MESSAGE = '4th one, for 2nd system'.
wa-system = '2ND_SYSTEM'.
APPEND wa to wt.

*-- now pass final table
LOOP AT pt into ps.
ts-system = ps.
wt2 = wt."temp table
DELETE wt2 where system NE ts-system. " so you have only only 1 systems data
ts-include = wt2.
append ts to tb.
ENDLOOP.

BREAK-POINT.

by the way this include in the type declaration has nothing to do with key word INCLUDE. you can write ABC here .. that also will work

types: begin OF testy,
           system type BAPILOGSYS,
           include type  BAPIRET2_T."-- you can write abc type bapiret2_t
types: end of testy.
