Creating and Displaying of Comments in ABAP List-Based PI Sheets 

Use

During a process, unplanned events such as delays or malfunctions may occur which affect the execution of the process instructions on your PI sheet. During PI sheet maintenance, you can create comments explaining, for example, these events and their effects.

Features

The R/3 System distinguishes between two types of comment:

The comment sheet is not linked to a specific object within the PI sheet. It can be changed until the status of a PI sheet is set to "complete"; see Maintaining Comment Sheets.

If you have maintained a comment sheet, this is indicated via the pushbutton Comment sheet in the PI sheet header. You can use this pushbutton to access existing comments both in the maintenance and in the display mode; see Displaying Comment Sheets.

This type of comment is always linked to a specific processing step (control instruction) within the PI sheet.
If you have maintained a comment on a processing step, the document symbol and the start of the comment are displayed at the right of the corresponding control instruction. You can call up and change a comment until it is reported; see
Maintaining Comments on Processing Steps.

The comments are reported using process messages of a category PI_COMM which has been predefined for this purpose by SAP. They are reported along with the other data for the respective processing step (see Reporting of Data).

When you display a PI sheet, you cannot create or report new comments, but you can display the existing ones; Displaying Comments.
