• What is the cause and solution for SAP error message WSUBST030 - Substitution not applied according to Cust.: &1; Typ 3 is supported only! ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WSUBST030 Substitution not applied according to Cust.: &1; Typ 3 is supported only!
  
  Meaning / Cause:
  
  This error occurs during the processing of substitutions in SAP (typically in Financial Accounting or Controlling modules).
  The substitution rule you are trying to apply is not executed because the substitution type you are using is not supported for the given customization.
  Specifically, the message indicates that only substitution type 3 is supported in the current context, but the substitution you are trying to apply is of a different type.
  Substitution types in SAP define when and how substitutions are triggered (e.g., type 1, 2, 3, etc.). Type 3 usually refers to substitutions that are applied during document posting or validation.
  The error means that the substitution configuration or the substitution rule is not aligned with the allowed substitution type for the customizing or the transaction.
  
  
  When does it occur?
  
  When you try to post a document or run a substitution rule that is not of type 3, but the system/customizing only supports type 3 substitutions in that context.
  For example, in Financial Accounting (FI), certain substitution types are only valid in certain areas or processes.
  
  
  Solution:
  
  
  Check the substitution type:
  
  Go to the substitution configuration in transaction GGB0 (for FI substitutions).
  Verify the substitution type assigned to the substitution rule.
  Ensure that the substitution type is 3 if the system/customizing only supports type 3 in this context.
  
  
  
  Adjust the substitution rule:
  
  If the substitution is of a different type (e.g., type 1 or 2), change it to type 3 if possible.
  Alternatively, create a new substitution rule of type 3 that fulfills your business requirement.
  
  
  
  Review customizing:
  
  Check the substitution customizing in the IMG under:
  Financial Accounting (New) -> Financial Accounting Global Settings (New) -> Document -> Substitutions -> Define Substitutions
  Confirm which substitution types are allowed for the relevant application area.
  
  
  
  Check the substitution assignment:
  
  Make sure the substitution is assigned correctly to the relevant company code, document type, or transaction.
  
  
  
  Consult SAP Notes:
  
  Sometimes, this error can be related to specific SAP versions or patches. Check SAP Notes for any known issues or corrections.
  
  
  
  
  Additional Information:
  
  
  Substitution Types in SAP FI:
  
  Type 1: Substitution at the time of document entry (before posting).
  Type 2: Substitution at the time of posting.
  Type 3: Substitution during document validation.
  
  
  
  The system restricts substitution types depending on the process step and customizing.
  
  
  This error is a safeguard to prevent invalid or unsupported substitution logic from being applied, which could cause inconsistent or incorrect postings.
