Assigning values to a deep structure

[Former Member]

Hi all,

I am trying to pass values to a deep structure but not able to do so.

Kindly guide as what is the approach to assign values in such a scenario.

See below the details :

ZIFLIGHT (structure) : Inside this ZFLIGHT_TT (table type) : Inside this ZIFLIGHT_ALL (line type) : Inside this three structure : CONTROL, DATA & DATAX.

Control has 1 field, values has to be assigned to this field.

data and datax has got 11 fields each; values to be assigned to be this field.

ZIFLIGHT (Top structure)

     |

ZFLIGHT_TT (table type)

     |

ZIFLIGHT_ALL (line type)

     |

CONTROL(structure with 1 field)

DATA(structure with 11 fields)

DATAX(structure with 11 fields)

I am trying to do it by using field-symbols e.g.

LOOP AT ITAB ASSIGNING <FS_ITAB>.

ASSIGN COMPONENT 'ZFLIGHT_TT' OF STRUCTURE ZIFLIGHT TO <FS_ZIFLIGHT>.

IF SY-SUBRC EQ 0.

ASSIGN COMPONENT 'ZIFLIGHT_ALL' OF STRUCTURE <FS_ZIFLIGHT> TO <FS_ZIFLIGHT_ALL>.

IF SY-SUBRC EQ 0.

ASSIGN COMPONENT 'CONTROL' OF STRUCTURE <FS_ZIFLIGHT_ALL> TO <FS_CONTROL>.

IF SY-SUBRC EQ 0.

<FS_CONTROL>-TASK = <FS_ITAB>-VALUE.

ENDIF.

ENDIF.

ENDIF.

ENDLOOP.

But it is not working and giving me dumps. Tried various combinations but not working, kindly guide.

Thanks,

Pradeep

Hi Pradeep,

basically it should work like that.

One thing that looks strange to me: in your first ASSIGN you use structure ZIFLIGHT -> is that correct? Means: is that your specific variable to be filled?

If that is not the issue, can you please give us a hint about the specific DUMP? A working (technically) code snippet might also help, so we can test "the real thing" and not have to simulate the behaviour in our heads.

Best regards,

Thorsten

Hi Pradeep,

First, let's do it using direct names to see what is wrong.

To access ZFLIGHT_TT, you can simple use:

ZIFLIGHT-ZFLIGHT_TT

But this is an internal table, so if you want its records next step is a loop.

LOOP AT ZIFLIGHT-ZFLIGHT_TT INTO WA_FLIGHT_TT.

Now, you can access your structure in this WA_FLIGHT_TT.

WA_FLIGHT_TT-ZIFLIGHT_ALL-CONTROL
WA_FLIGHT_TT-ZIFLIGHT_ALL-DATA
WA_FLIGHT_TT-ZIFLIGHT_ALL-DATAX

Your job now is adjust this code to use field-symbols.

Hope it helps,

Hi Pradeep,

the cause of your problem is, that you try to access a component of a table! This won't work.

Let's see in detail:

ASSIGN COMPONENT 'ZFLIGHT_TT' OF STRUCTURE ZIFLIGHT TO <FS_ZIFLIGHT>.

IF SY-SUBRC EQ 0.

OK so far - but the next won't work. First you'll have to

LOOP AT <FS_ZIFLIGHT> ASSIGNING <FS_ZIFLIGHT_L>.

and than change to

ASSIGN COMPONENT 'ZIFLIGHT_ALL' OF STRUCTURE <FS_ZIFLIGHT> TO <FS_ZIFLIGHT_ALL>.

ASSIGN COMPONENT 'ZIFLIGHT_ALL' OF STRUCTURE <FS_ZIFLIGHT_L> TO <FS_ZIFLIGHT_ALL>.

IF SY-SUBRC EQ 0.

ASSIGN COMPONENT 'CONTROL' OF STRUCTURE <FS_ZIFLIGHT_ALL> TO <FS_CONTROL>.

IF SY-SUBRC EQ 0.

<FS_CONTROL>-TASK = <FS_ITAB>-VALUE.

ENDIF.

ENDIF.

ENDLOOP.

ENDIF.

Hope it helps.

Best regards
