• What is the cause and solution for SAP error message /INCMD/MSG160 - Restricted interchangeability group &1 is not allowed in PSPs ?

  The SAP error message /INCMD/MSG160 Restricted interchangeability group &1 is not allowed in PSPs typically occurs in the context of production planning and control, particularly when dealing with interchangeability groups in the context of production scheduling or planning.
  Cause:
  This error indicates that the system has encountered a restricted interchangeability group that is not permitted in the Production Scheduling Profiles (PSPs) you are trying to use. Interchangeability groups are used in SAP to define which materials can be substituted for one another in production processes. If a material belongs to a restricted interchangeability group, it may not be allowed for certain operations or in specific contexts, such as when creating production orders or scheduling.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Interchangeability Group Settings:
  
  Go to the material master data for the affected material and check the interchangeability group assigned to it. Ensure that it is correctly set up and that it is not marked as restricted if it needs to be used in the PSP.
  
  
  
  Review Production Scheduling Profile:
  
  Check the settings of the Production Scheduling Profile (PSP) you are using. Ensure that it allows for the interchangeability group in question. You may need to modify the PSP to include the necessary interchangeability groups.
  
  
  
  Consult with Configuration Team:
  
  If you do not have the necessary permissions to change the settings, consult with your SAP configuration team or the person responsible for maintaining the material master and PSP settings. They can help adjust the configurations as needed.
  
  
  
  Check for Dependencies:
  
  Sometimes, the interchangeability group may be restricted due to dependencies with other materials or production processes. Review any related materials or processes that might be influencing this restriction.
  
  
  
  Documentation and Support:
  
  Refer to SAP documentation or support notes related to interchangeability groups and PSPs for more detailed guidance. You can also check SAP Community forums for similar issues and solutions shared by other users.
  
  
  
  Related Information:
  
  Interchangeability Groups: These are defined in the material master and are used to manage the substitution of materials in production.
  Production Scheduling Profiles (PSPs): These profiles define how production orders are scheduled and can include various parameters that affect the scheduling process.
  Material Master Data: This is a central repository of information related to materials in SAP, including details about interchangeability groups.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
