SAP Note 25006 - Structuring the process instruction sheet

Symptom:

The heading 'Phase: XXXX / Process instruction number: YYYY' is not displayed in front of some phases in the process instruction sheet. The process instructions that belong to these phases are displayed directly after the last displayed process instruction of the previous phase.

Cause and prerequisites

The heading 'Phase: XXXX / Process instruction number: YYYY' is only created in front of process parameters (process instruction category 1).
If you do not define a process parameter for a phase, the respective process instructions are directly appended to the preceding phase.

Solution
The heading only serves for orientation purposes in the process instruction sheet.
