What is time-based constraint in SAP SCM-APO-SNP - Supply Network Planning (SNP)?

SAP Term: time-based constraint

• Component: SCM-APO-SNP

• Component Name: Supply Network Planning (SNP)

• Description: Constraint that can be defined in interactive Supply Network Planning on a time basis; that is, for specific periods, for the SNP optimization run. The following bounds limits can be defined as time-based constraints: Upper bound for procurement at product-location level Upper bound for stock on hand at product-location level Upper bound for production at product-PPM level Upper bound for transportation at product-transportation lane level

• Key Concepts: 
  Time-based constraints are used in Supply Network Planning (SNP) to define the earliest and latest dates for a certain activity or event. These constraints are used to ensure that the supply chain is running efficiently and that all activities are completed on time. 
  
  How to use it: 
  Time-based constraints can be set up in the SNP planning book. The user can define the earliest and latest dates for each activity or event, as well as the duration of the activity. The system will then use these constraints to calculate the optimal plan for the supply chain. 
  
  Tips & Tricks: 
  It is important to ensure that the time-based constraints are realistic and achievable. If they are too tight, it may not be possible to meet them, resulting in delays and disruptions in the supply chain. 
  
  Related Information: 
  Time-based constraints are closely related to capacity constraints, which define the maximum amount of resources that can be used for a certain activity or event. Both types of constraints are used to ensure that the supply chain is running efficiently and that all activities are completed on time.
