Program Naming Convention

There are two program types:

• Reports
  
  
• Dialog programs
  

Each program type has its own naming conventions. Table A.1 contains the characters
that are not allowed in program names

Table A.1 Invalid Characters for Program Names

Character	Description
.	Period
,	Comma
	Blank
( )	Parentheses
'	Single quote
"	Double quote
=	Equal sign
*	Asterisk
_	Underscore
%	Percent sign
Ä ä Ö ö Ü ü ß	Umlaut and "scharfes s" characters

Naming Conventions for Reports

Customer report names follow the convention Yaxxxxxx or Zaxxxxxx,
where:

• The first character must be a Y or Z.
  
  
• The second character represents the application area.
  
  
• The maximum program length is 10.
  

The second character is the short form for the application area (see Table A.2).
For example, a customer report for Treasury would follow the convention Z5xxxxxx,
while a logistics report would be named Z21xxxxx.

Each application area can be represented by a code. Each code has two commonly
used forms, the short form and the long form. There is also a code used only for
logical database names. These codes are shown in Table A.2.

Table A.2 Codes for the Application Areas in R/3

Application Area	Long Form	Short Form	LDB Form
Financial Accounting	FI	1	F
Materials Management	MM	2	M
Sales and Distribution	SD	3

Asset Accounting	AA	11
Controlling	CO	12
Process Industries	PI	13
Investment Management	IM	14
Logistics (General)	LO	21
International Development	IN	22
Cross Application Functionality	CA	23

Naming Conventions for Dialog
Programs

Customer dialog program names follow the convention SAPMYxxx or SAPMZxxx,
where:

• The first four characters must be SAPM.
  
  
• The fifth character must be a Y or Z.
  
  
• The last three characters may be any valid characters.
  

Programs written by SAP follow the convention SAPMaxxx, where a
is the short form for an application area.

Customer Name Ranges

The R/3 system contains many types of development objects. If you want to create
a development object yourself, you must create it in the customer name range.
The conventions for customer name ranges are shown in Table A.3.

You will find that a few SAP objects exist within customer name ranges and thus intrude
on the above naming conventions. These objects were created before the preceding
conventions were adopted. A list of these exceptions can be found in table TDKZ.
