MDG API -> Get Change Document

[cmetz]

Hey guys,

I got the requirement to display the Change Document of a Change Request (With old an new values). I could't find an appropriate method in the Convenience and Governance API.

After searching a while, I found out that there is a class CL_USMD_MDF_CHANGE_DOCUMENT. This class has the method Read_document_lines. Am I on the right track? When calling this method I have to pass a model as parameter and i don't know how get this.

Can anyone please put some light on this ;-).

Thanks and regards

Chris

Thanks Sanjay for your reply. This seems to be WebDynpro specific, but I want to show this values in Fiori, so I need to write ABAP code in the backend.

Hi Chiris

Do you want in Fiori apps (Request or Approval). Also pleas check

We are implementing an approval app (Approve Request/ My Inbox App) for Fiori, there is no SAP Standard for this at the moment, so this document is not helpful for me.

The important question is, how can I get the change document of a change request with abap code? Someone here with expierence in that field?

Hi Christoph,

To get a model instance use the following class

*    "Create Instance of the Model
     CALL METHOD CL_USMD_MODEl=>GET_INSTANCE
       EXPORTING
         I_USMD_MODEL = (Data model name)
       IMPORTING
         EO_INSTANCE  = LO_MODEL
         ET_MESSAGE   = LT_MESSAGE.

You are using the right class , first determine the header details using READ_DOCUMENT_HEADER and then use read_document_lines

Hi Chris

Are you on MDG7.0 with SP06 or MDG7.0 with SP04?

Hi Raghu,

thanks for your answer.  This was also my idea. The problem is, that if I call the method CL_USMD_MODEl=>GET_INSTANCE I get back TYPE IF_USMD_MODEL_EXT... and the Method READ_DOCUMENT_HEADER  expects TYPE IF_USMD_MODEL.... How to solve that issue?

Thanks + regards

Chris

Hi Christoph,

That is strange.CL_USMD_MODEL=>get_instance does return instance of CL_USMD_MODEL. Please see the screen shot below
