• What is the cause and solution for SAP error message WT123 - Requirement group &1 does not exist ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WT123 Requirement group &1 does not exist
  
  Cause:
  This error occurs when the system tries to reference a requirement group (also called a requirement type or requirement group key) that has not been defined or maintained in the system. Requirement groups are used in SAP to control the availability check and requirements determination in production planning and sales order processing.
  In particular, this error typically arises in the context of:
  
  Availability check (ATP check)
  Requirements grouping in MRP or sales order processing
  Configuration of requirement types in Customizing
  
  The system is looking for a requirement group with the key specified (represented by &1 in the message), but it cannot find it in the configuration tables.
  
  Where is the Requirement Group Maintained?
  Requirement groups are maintained in the SAP Customizing under:
  
  SPRO ? Production ? Material Requirements Planning ? Check Availability ? Define Requirement Groups
  
  or
  
  SPRO ? Sales and Distribution ? Basic Functions ? Availability Check and Transfer of Requirements ? Define Requirement Groups
  
  
  Solution:
  
  
  Check the Requirement Group Key:
  
  Identify the requirement group key that is causing the error (the value of &1).
  Verify if this key exists in the system.
  
  
  
  Maintain the Requirement Group:
  
  Go to transaction SPRO ? navigate to the path mentioned above.
  Define or maintain the missing requirement group.
  Assign the necessary parameters such as description, group type, and relevant settings.
  
  
  
  Check Customizing for Availability Check:
  
  Sometimes, the requirement group is linked to the availability check or requirements type in sales or production.
  Ensure that the requirement group is correctly assigned in the relevant configuration.
  
  
  
  Check Master Data and Transactions:
  
  If the error occurs during a transaction (e.g., sales order, production order), check if the material master or document references a requirement group that does not exist.
  Correct the master data or document accordingly.
  
  
  
  Transport and System Consistency:
  
  If this error appears after a transport or system copy, verify that the customizing for requirement groups has been transported correctly.
  Missing customizing in the target system can cause this error.
  
  
  
  
  Related Information:
  
  Requirement Groups are used to group requirements for availability check and MRP purposes.
  They help in controlling how requirements are summed up or separated during planning.
  Requirement groups are linked to Requirement Types and Checking Groups.
  The error message is a standard message from the availability check or requirements determination logic.
