• What is the cause and solution for SAP error message COM_ATTRFRG_GEN221 - Multiple-value attributes are only permitted in multiple-use set types ?

  The SAP error message COM_ATTRFRG_GEN221 indicates that there is an issue with the use of multiple-value attributes in a context where they are not allowed. This error typically arises in the context of SAP's Classification System, particularly when dealing with characteristics and classes in the context of material management or product data management.
  Cause:
  The error occurs when you attempt to assign a multiple-value attribute to a single-use set type. In SAP, attributes can be defined as either single-value or multiple-value. A single-use set type can only hold one value for a given attribute, while a multiple-use set type can hold multiple values. If you try to assign a multiple-value attribute to a single-use set type, SAP will throw this error.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Attribute Definition: Review the definition of the attribute that is causing the error. Ensure that it is defined correctly as a multiple-value attribute if you intend to use it in a context that requires multiple values.
  
  
  Change Set Type: If the attribute is indeed a multiple-value attribute, you need to ensure that it is assigned to a multiple-use set type. You can do this by:
  
  Navigating to the classification system in SAP.
  Modifying the class or set type to allow for multiple values.
  If necessary, create a new multiple-use set type that can accommodate the multiple-value attribute.
  
  
  
  Review Class Assignment: Ensure that the class to which the attribute is assigned is compatible with multiple-value attributes. If the class is set up as a single-use class, you may need to change its configuration.
  
  
  Data Entry: If you are entering data, ensure that you are not trying to input multiple values into a field that is set up to accept only a single value.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on setting up attributes and classes correctly.
  
  
  Related Information:
  
  SAP Classification System: Understanding how the classification system works in SAP can help prevent such errors. Familiarize yourself with the concepts of characteristics, classes, and set types.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CL02 (Change Class), CL03 (Display Class), and CL01 (Create Class) to manage your classification data effectively.
  
  By following these steps, you should be able to resolve the COM_ATTRFRG_GEN221 error and ensure that your attributes are set up correctly in the SAP system.
