• What is the cause and solution for SAP error message AD094 - An underscore is not permitted in position 2 or 3 ?

  The SAP error message AD094 indicates that there is an issue with the naming convention of an object, typically a variable, field, or identifier, in your ABAP code or configuration. Specifically, the error states that an underscore (_) is not permitted in the second or third position of the name.
  Cause:
  The error is caused by the naming rules in ABAP, which restrict the use of underscores in certain positions within identifiers. According to the naming conventions:
  
  The first character of an identifier must be a letter (A-Z, a-z).
  The second and third characters cannot be underscores.
  Subsequent characters can include letters, numbers, and underscores.
  
  For example, the following identifiers would trigger this error:
  
  _example (underscore in position 1)
  a_bexample (underscore in position 2)

  To resolve this error, you need to modify the identifier that is causing the issue. Here are the steps to fix it:
  
  
  Identify the Object: Check the error message details to find out which identifier is causing the issue. This could be a variable, field name, or any other identifier in your code.

  The first character is a letter.
  The second and third characters are not underscores.

  For example, if the identifier is a_bexample, you could rename it to ab_example or a1_example.
