Hi Nayeem
On SAP GUI
1. My test user have R/3 authorizations to create documents(CV01N) when the document type is not marked 'USE ACM' in customizing.
2. Once this document type is marked 'USE ACM', the test user can no longer create documents of this document type. The error message is 'You are not authorized to create document with type HRT. Message No. /PLMI/CV001'.
3. Then I add auth-object 'PLM_TRUSR', once again the test user is able to create the document of this type.
I assume that this is a sign which tells me ACM has some effects on documents on SAP GUI.
