Getting GETWA_NOT_ASSIGNED error while developing ALV report without using field catalog.

[sandip_dasgupta]

I am just trying to develop an ALV report without using field catalog to display MATNR,MBRSH,MTART & MEINS field for a range of material input, Below is the code for the ALV report using FM 'Reuse_alv_list_display' ....

The error which i am getting is GETWA_NOT_ASSIGNED with this explanation

Error analysis

    You attempted to access an unassigned field symbol

    (data segment 93).

    This error may occur if

    - You address a typed field symbol before it has been set with

      ASSIGN

    - You address a field symbol that pointed to the line of an

      internal table that was deleted

    - You address a field symbol that was previously reset using

      UNASSIGN or that pointed to a local field that no

      longer exists

    - You address a global function interface, although the

      respective function module is not active - that is, is

      not in the list of active calls. The list of active calls

      can be taken from this short dump.

  Now my question is

  1. Why i am getting this error as i have not mentioned any field catalog ?

  2. When i am using FM "Reuse_alv_grid_display" that time i am getting the output...why ???

hi,

replace

* IMPORTING

with

IMPORTING

[sandip_dasgupta]

hiii abdul ,

               I am not getting what you want to say ...Please explain me why i am getting this error ? and if i use another FM then y i am not getting that error ? 

[ralf_wenzel_heuristika]

You're wrong, because all importing parameters are commented, there is no need to uncomment keyword "importing". This would cause a syntax error.

[ralf_wenzel_heuristika]

This error is regularly caused by an incorrect field catalog. In your case, you say i_structure = 'MARA', but your ty_mara does not match all mara fields. This results into a pointer (running over all MARA fields) does not find some MARA fields in your ty_mara.

THe ALV grid does work completely different from this procedure, so this error won't occur.

[former_member184158]

Hallo

so you have 2 options,

1. Convert you fields to field catalog and pass the fieldcatlog to FM with your ITAB

2. or pass the structure and ITAB ( must be same ) to FM.

what you have done?

you have passed the ITAB which is different from the structure. ( cause Error)

so try this code, hopfully it will help you .

Hi Ebrahim ,

               Thanks for your solution but i know that. My question was why i am getting GETWA_NOT_ASSIGNED error in this program and i think as mentioned by RALF this is the reason for this error.

   Please correct me if i am wrong ....

Regards....

[sandip_dasgupta]

Thanks Folks for your suggestions but my 2nd question is still unanswered .... Please help me out to solve it.

Hi,

  2. When i am using FM "Reuse_alv_grid_display" that time i am getting the output...why ???

let me to explain it for you please,

FM:  Reuse_alv_LIST_display

this function module, converts the whole structure (MARA) to field catalog and compare the field catalogs with your ITAB , if one field from MARA  i_structure_name = 'MARA'
does not match your ITAB ( does not exist in ITAB) , it will generate a DUMP.

But

FM:  Reuse_alv_GRID_display   has another technic, and it handles different.

this function is different from LIST,

it depends on ITAB and the structure,

if ITAB has 3 , A, B, C columns, and the structure has 6 columns , A,B.,C. D,. E, F., G

now it compares between the ITAB and the structure , if all fields of ITAB belongs to structure . then it will assign the value and generate the ALV; ,if not , it  will generate a dump.

in your example i_structure_name = 'MARA' has more than 200 fields, and you ITAB has 4 fields, but the all of them belong to Mara,so it will generate the output, and assign the values, to MARA fields.

This FM, assign the values of ITAB to structure,

if your ITAB MARA, and your structure is SFLIGHT, but your ITAB is empty, it will generate an ALV-GRID with empty value, only fields name,

it will generate dump when you ITAB MARA has values, after assing the values, to structureSFLIGHT, it will find out, that SFLIGHT has not field with your ITAB , MATNR, etc,then it will generate a dump

if you try out to execute it without to fill theITAB, you will get only the structure of SFLIGHT. The error occurs during assigning the values of ITAB and it will realize that your ITAB does not match the structure.

At the end, they are different FMs:

Hopfully I could explain it good for you.

Regards

Ebrahim

That's what I said repeatedly - with more details. But I thinks that's not what he wants to read

[former_member184158]

Hallo Ralf,

you are right,you have written it before, but he could not get it, as I think. So I have tried to explain it more

[ralf_wenzel_heuristika]

As I told you, the grid works completely different due to fieldcatalog handling.
