• What is the cause and solution for SAP error message 0H455 - Assign only sequential items to a group ?

  The SAP error message 0H455 ("Assign only sequential items to a group") typically occurs in the context of creating or managing groups of items in SAP, particularly in the areas of inventory management, production planning, or sales and distribution. This error indicates that the items you are trying to assign to a group are not sequential, which is a requirement for certain operations in SAP.
  Cause:
  The error arises when you attempt to group items that do not follow a sequential order. For example, if you are trying to assign a range of materials or documents, they must be in a continuous sequence (e.g., 1001, 1002, 1003) rather than having gaps (e.g., 1001, 1003, 1004).
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Item Sequence: Review the items you are trying to group. Ensure that they are in a continuous sequence without any gaps. If there are gaps, you will need to either:
  
  Remove the non-sequential items from the group.
  Adjust your selection to include only those items that are sequential.
  
  
  
  Recreate the Group: If you have a large number of items, it may be easier to recreate the group by selecting only the sequential items from the start.
  
  
  Consult Documentation: Refer to SAP documentation or help files related to the specific module you are working in (e.g., MM, SD, PP) for more detailed guidance on grouping items.
  
  
  Check Customizations: If your organization has customized SAP, check with your SAP administrator or technical team to see if there are any specific rules or configurations that might be affecting item grouping.
  
  
  Use Transaction Codes: If applicable, use transaction codes like MM01 (Create Material), VA01 (Create Sales Order), or others relevant to your context to ensure you are following the correct procedures for item grouping.
