• Key Concepts: 
  Alternative item groups are used in SAP Production Planning and Control (PP) to group together different materials that can be used as substitutes for each other. This allows for the substitution of one material for another in the production process, without having to manually change the bill of materials (BOM). 
  
  How to use it: 
  Alternative item groups are created in the SAP system by assigning a group number to each material that can be used as a substitute. This group number is then assigned to the BOM, so that when a material is selected, all materials with the same group number are also available as substitutes. 
  
  Tips & Tricks: 
  When creating alternative item groups, it is important to ensure that all materials in the group are compatible with each other and can be used interchangeably in the production process. It is also important to keep track of which materials are part of which group, so that they can be easily identified when needed. 
  
  Related Information: 
  Alternative item groups are closely related to material variants, which are used to define different versions of a material that can be used in the production process. For more information on material variants, please refer to SAP's documentation on the topic.
