What is sequence definition in SAP PP-PI - Production Planning for Process Industries?

SAP Term: sequence definition

• Component: PP-PI

• Component Name: Production Planning for Process Industries

• Description: A process instruction that you use at the start of a phase to specify that this phase can only be processed in the PI sheet after you have finished processing another phase. By generating sequence definitions automatically, you can copy the phase relationships entered in the process order to the PI sheet. In the PI sheet, the process instructions of the phase containing the sequence definition remain inactive until all message data has been reported for the predecessor phases. The system only recognizes phases from the same PI sheet.

• Key Concepts: 
  Sequence definition is a feature in the Production Planning for Process Industries (PP-PI) component of SAP that allows users to define the order of operations for production processes. It enables users to create a sequence of operations that must be completed in order for a product to be produced. This sequence can be used to control the flow of materials and resources throughout the production process. 
  
  How to use it: 
  Sequence definition is used to define the order of operations for production processes. To create a sequence, users must first define the individual operations that make up the sequence. Once these operations have been defined, users can then assign them to a sequence and specify the order in which they should be completed. The sequence can then be used to control the flow of materials and resources throughout the production process. 
  
  Tips & Tricks: 
  When creating a sequence, it is important to consider the resources and materials that will be needed for each operation. This will help ensure that all necessary resources are available when needed and that there are no delays in production due to lack of materials or resources. Additionally, it is important to consider any safety or quality requirements that must be met during each operation in order to ensure that products are produced safely and meet quality standards.
