Configuration in the CO (Controlling) Modules requires maintenance of number ranges for documents generated from business transactions. A systems� generated document number is assigned for every CO (Controlling) posting. These numbers are sequential and are required to be assigned to number range groups. The number range groups consists of two number intervals, one for internal document numbering and one for external document numbering. The SAP R/3 system keeps track of those document numbers that are externally generated and fed to SAP via batches and User manual input, otherwise, the system generates the next internally assigned document number for the transaction posted.
As previously stated when defining the Controlling Area, you have the ability to copy the Standard SAP Controlling Area �0001� which already has the number ranges defined eliminating the need for maintenance of number ranges. Keep in mind that you also have the flexibility to change number ranges and number range groups to meet your business needs. As a caution, never overlap number intervals in a group . For example, if you decide to assign number range interval 10000000 thru 199999999 to the number range group �05�, you can not assign it to number range group �06�. Number ranges should never be transported for data consistency purposes, therefore create these manually in each system.
Within the CO (Controlling) Module, you can configure Plan Versions. Maintaining Plan Versions allows for set-up of planning assumptions and determination of plan rates for allocation and plan activity purposes. The SAP Standard Version �000� is created for a five year fiscal year plan. It is recommended that the standard version be utilized for your plan/actual comparisons if you do not require multiple plan versions. SAP always allows the flexibility to create additional Plan versions by coping the Standard Version �000� and changing certain fields as required. There is also the option of defining and creating a totally new Plan Version.
