• What is the cause and solution for SAP error message STC_TM158 - Character '&&' in variant name &1 only allowed for transportable variants ?

  The SAP error message STC_TM158 indicates that there is an issue with the naming convention of a variant in the SAP system. Specifically, the error states that the character '&&' is only allowed in the names of transportable variants. Here’s a breakdown of the cause, solution, and related information for this error:
  Cause:
  
  The error occurs when a variant name includes the character '&&', which is not permitted for non-transportable variants. In SAP, variants are used to store selection criteria for reports and programs, and there are specific rules regarding the naming of these variants.
  The presence of '&&' in the variant name suggests that it may have been intended for a transportable variant, but it is being used in a context where only non-transportable variants are allowed.
  
  Solution:
  
  
  Rename the Variant: 
  
  If the variant is not intended to be transportable, you should rename it to remove the '&&' characters. Use a naming convention that adheres to the rules for non-transportable variants.
  For example, change the variant name from MyVariant&&Test to MyVariant_Test or any other valid name that does not include '&&'.
  
  
  
  Check Variant Type:
  
  If the variant is supposed to be transportable, ensure that it is created in the correct context (e.g., in a transportable environment) and that it is marked as transportable.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation or help resources for guidelines on naming conventions for variants to ensure compliance with the system's requirements.
  
  
  
  Related Information:
  
  Transportable Variants: These are variants that can be transported between different SAP systems (e.g., from development to production). They often have specific naming conventions that allow for special characters.
  Non-Transportable Variants: These are variants that are local to a specific client and do not have the same naming flexibility as transportable variants.
  SAP Notes: Check for any relevant SAP Notes that may provide additional context or updates regarding this error message.
  
  By following these steps, you should be able to resolve the STC_TM158 error and ensure that your variant names comply with SAP's naming conventions.
