In many cases, the naming conventions for BDC sessions need to be worked in conjunction with the Security Administrato

15、r.Considerations:BDC session names do not require unique names.BDC security may be set up based on the name of the BDC session.A BDC session with a Company Code embedded in the name may be beneficial.In many circumstances, end-users will be required to process BDC sessions; this should be taken into

16、 account when establishing BDC naming conventions.4. Data ElementsStandard:DO NOT create new data elements, use standards SAP data elements where it is possible. New data elements must be activated for better tracking purposes. Where possible, use the same name as the domain associated with the data

17、 element. If there is a conflict, name the data element in a meaningful manner. SAP does create Data Elements that begin with a Z, so custom Data Elements should begin with ZZ.Data element names should have a maximum of 8 characters.

ENHANCEMENT PROJECTSThe R/3 enhancement concept allows you to add your own functionality to SAPs standard business applications.Standard Format:Enhance

FUNCTION GROUPSConsiderations:When function modules are called, the system lo

44、t accesses common processing modules, checks and processes user inputs during a transaction. The module pool is also a means of linking all the associated screens, menus and function keys of the interface as a transaction.Unlike an ABAP/4 program, a module pool consist entirely of Include programs.

45、These Includes contain the appropriate processing logic. Include programs have a program attribute type of I.Standard Format:Screen module pool names should begin with SAPMZ followed by a 1 character functional descriptor. The last 3 digits of the name should be a unique alpha-numeric identifier. In

46、cludes form module pools should be generated by SAP and the name generated should not be changed.SAPMZxx|Alphanumeric Identifier|Functional DescriptorIndicates Dialog Module poolPosition DescriptionValuesMeaning1-5IdentifierSAPMZCustom Module Pool for Screen6Functional Descriptor(A-Z)(see functional
