Edit your question, select your coding and press the CODE button to make it more readable. Thanks 😛

After you have better formatted your code, please also explain which "compiler error" message you have, and we'll answer to you.

It's (I guess) at the beginning of the post:

Compilation Error Message: The data object "LAYOUT KEY" has no structure therefore no component called "Report"

I guessed it's because the data object "layout key" has been declared as a reference of something. But I can be wrong (I use to be).

Attn Sandra/Vicenc - have reformatted the relevant part of code as below, trust it will be more helpful. ERP 6.0 EHP7 system.

METHOD SET_LAYOUT.
DATA: LAYOUT TYPE REF TO CL_SALV_LAYOUT,
LAYOUT_KEY TYPE REF TO SALV_S_LAYOUT_KEY.
LAYOUT = ALV_TABLE_OBJECT->GET_LAYOUT ( ).
LAYOUT_KEY-REPORT = SY-REPID.
LAYOUT->SET_KEY(LAYOUT_KEY).
LAYOUT->SET_SAVE_RESTRICTION(IF_SALV_C_LAYOUT=>RESTRICT_NONE).
ENDMETHOD.

The data object “LAYOUT_KEY” has no structure and therefore no component called “REPORT”

as Vicenc there seems to be a type ref problem in the highlighted statement as "SALV_S_LAYOUT_KEY." has 3 components name as below but these are not being transferred to "LAYOUT_KEY". Will be very grateful for your help thanks:

Sorry, but only you can close the question.

Sorry but good formatting is as follows:

  METHOD SET_LAYOUT.
    DATA: LAYOUT TYPE REF TO CL_SALV_LAYOUT,
    LAYOUT_KEY TYPE REF TO SALV_S_LAYOUT_KEY.
    LAYOUT = ALV_TABLE_OBJECT->GET_LAYOUT( ).
    LAYOUT->SET_KEY(LAYOUT_KEY).
    LAYOUT->SET_SAVE_RESTRICTION(IF_SALV_C_LAYOUT=>RESTRICT_NONE).
  ENDMETHOD.
ENDCLASS.

You probably didn't post the code corresponding to the error message:

The data object “LAYOUT_KEY” has no structure and therefore no component called “REPORT”

But in your post, you had these lines:

    DATA: 
          LAYOUT_KEY TYPE REF TO SALV_S_LAYOUT_KEY.

    LAYOUT->SET_KEY(LAYOUT_KEY).

so I guess you have in the actual code something like this:

    DATA: 
          LAYOUT_KEY TYPE REF TO SALV_S_LAYOUT_KEY.

    LAYOUT_KEY-REPORT = sy-repid.

the issue being that you defined LAYOUT_KEY as a reference variable (REF TO) to a structure, a reference variable has no structure itself, it just contains a reference

So either don't define it as a reference:

    DATA: 
          LAYOUT_KEY TYPE SALV_S_LAYOUT_KEY.

    LAYOUT_KEY-REPORT = sy-repid.

or refer to the referenced object using the dereferencing operator like that:

    DATA: 
          LAYOUT_KEY TYPE REF TO SALV_S_LAYOUT_KEY.

    LAYOUT_KEY->REPORT = sy-repid.
