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. SAP generated programs or functions may use this dictionary object
