Type 7: Sequence Definitions (SAP Library - Process Management (PP-PI-PMA))

Type 7: Sequence Definitions

In a sequence definition, you need to specify the number of the phase which has to be finished before the phase containing the sequence definition can be processed in the PI sheet.

Assign the following characteristic:

Characteristic

Meaning

Allowed values

PPPI_PREDECESSOR

Number of the phase which has to be processed first (predecessor phase)

Number of a phase contained in the current order

The characteristic PPPI_PREDECESSOR can be used only once in a sequence definition. If a phase has several predecessors, a separate sequence definition has to be created for each of them.

Notes on Using Sequence Definitions

Always insert sequence definitions at the start of a phase before the other process instructions.

Sequence definitions have been designed in order to transfer the phase relationships defined in a process order to the corresponding PI sheets. They are generated automatically if you have made the corresponding settings in Customizing for the control recipe destination. The value of the characteristic PPPI_PREDECESSOR is assigned automatically during the generation process.

Do not use sequence definitions in combination with hidden data requests for the following reasons:

Hidden data requests are not taken into account when the system checks whether a phase has been fully processed.
If hidden data requests are used at the start of a phase, it is possible that the corresponding messages are created at the wrong time or that they are not created at all because their phase is still locked when the previous message is sent.
