Mixed Number Assignment 
Usage
Mixed number assignment means that part of the document number can be assigned internally by the system, and the other part can be assigned by the user.
Mixed number assignment is supported for document type L01. The document number consists of the following two parts:
- First part of number:
In a specific program for controlling number assignment, the character string TRANS-01-ENG- is defined as a fixed part of the document number. The system enters this string in the Document number field.
- Second part of number:
The user assigns the second part from a defined external number range according to organizational criteria.
TRANS-01-ENG-01
TRANS-22-ENG-01
TRANS-43-ENG-01
