Can we read standard Change Documents in S/4HANA Cloud Public using class CL_CHDO_READ_TOOLS?

[DiegoValdivia]

Hi everyone,

In some SAP Blog posts and SAP Notes, it's mentioned to use class CL_CHDO_READ_TOOLS to read Change Document information.

Today, I created a test class to read change documents for object EINKBELEG (Purchasing Documents) and got some exception "You are not authorized to display change documents".

I did a test by reading a Custom Change Document and the code worked perfectly.

I have read all standard documentation mentioning class CL_CHDO_READ_TOOLS, but none of the pages mention any restriction related to reading Standard Change Documents.

SAP Help - Reading Change Documents 

This is my code:

CLASS zktest2 DEFINITION
  PUBLIC
  FINAL
  CREATE PUBLIC .

  PUBLIC SECTION.
   INTERFACES if_oo_adt_classrun.
ENDCLASS.

CLASS zktest2 IMPLEMENTATION.
  METHOD if_oo_adt_classrun~main.
    TRY.
        cl_chdo_read_tools=>changedocument_read(
          EXPORTING
            i_objectclass = 'EINKBELEG'
          IMPORTING
            et_cdredadd_tab = data(lt_cdredadd_tab)
          ).
      CATCH cx_root INTO DATA(lo_root).
        DATA(lv_message) = lo_root->get_text( ).
        out->write( lv_message ).
    ENDTRY.
  ENDMETHOD.
ENDCLASS.

has anyone faced this issue?

Hi Diego,

I tried to replicate the same code which you have pasted in a Dev 080 system of SAP S/4HANA Cloud Public Edition and I am able to see that usage of this class is allowed for cloud development

Could you try this again?
This could also be because you do not have the roles to access the object class 'EINKBELEG'

Thanks,

Hi Prasanth,

Thanks for your reply.

Quick question, when you executed the class, do you receive an exception? if so, could you share a screenshot of the exception text?

Hi Diego,

I did not get any exception while activating or executing the class after that. It was a straightforward implementation for me.

Thanks,
Prasanth

Thanks for your reply, Prasanth. I did a test on some On Premise 2023 system and was able to execute the class correctly. I'll investigate how identify and add the missing roles in S4 Cloud Public.
