Maintaining Character Sets 
The SAP system manages its own character sets. These characters sets specify:
· Which characters a particular printer or screen display routine can output
· the hexadecimal code to use to send a character to a printer or display routine.
The following topics describe how to maintain character sets in spool administration.
In general, you only need to maintain character sets when you add a new device type to the SAP system. To maintain character sets, do the following:
· Identify the manufacturer of the character set using Character Set Manufacturer.
You only need to perform this step if the manufacturer of the character set is not already identified in the spool system.
· Define the character set required by the printer using Character Sets.
To do this, you must:
– Identify which characters are in the character set using their SAP ID numbers
– Enter the binary code for each character, as required by the printer or display routine.
The easiest method for defining a character set is to copy the existing character set that most closely matches the new character set. Then add or delete characters as necessary to customize the character set.
