Hi
External is user defined (can be alphanumeric) and Internal is system defined (numeric) even you can say auto number.
For G/L master the number range is always external and we need to choose from the number range given to that particular account group which is defined in the chart of the accounts.
For Vendor, Customer, Asset masters - the number is assigned depending on the number range assigned to that particular account group. For example, for vendor if the group is local vendors, and if you assign that group with a number range variant 01 holding the number range interval 1000-1999 and if you don’t select the external check box, the first vendor created will be assigned with 1000 automatically by the system.
If you want to give the vendor the desired number say, vendor01 check the external box. Same procedure is followed with customers and asset masters.
For the Documents, the number is assigned to the documents in regards to the number range variant assigned to the document type. For example, for document type SA the number range variant is 02 with number range interval 2000 to 2999, whenever the document is created with SA as document type, the first document is created with 2000 after posting and followed sequentially if its internal. If you select the number range as external you need to provide the number before posting the document but from the same interval range of 2000-2999.
So when you post spl g/l, parked or recurring entries the document number depends on the number range interval given to the number range variant and the variant assigned to the document type.
In FBN1, for documents,
variant     year     number range     external
01     2007     10000-19999     
02     9999     20000-29999     
03     2007     30000-39999     
04     2007     40000-49999     
And we assign the above variants to the document types in OBA7.
For customers and vendors,
- Create account groups in OBD2, OBD3
- Create no ranges in XDN1, XKN1
- Assign no ranges for groups in OBAR, OBAS respectively.
Depreciation - Always external
Asset Masters – Either
GL A/cs – Always external
Vendor A/cs - Either
Customer A/cs - Either
May be lengthy but go through it slowly … trust me number ranges are based totally on logic. Its simple and easy. Hope this will serve your purpose.
