Migrating 3 company codes data to 1 company code.

Question

Hi all,
We are one legal entity, imparting educational training and operating its activities at three locations namely Gurgaon, Dehradun and
Rajamundary. In addition it has two administrative offices at Delhi and Mumbai besides a few other rented premises.
The implementation team has created one company as XYZ and created three separate company codes for each of the operational unit at Gurgaon, Dehradun and Rajamundary. All the existing company codes have been assigned to one Chart of Account. The operating units are neither independent legal entities nor are required to generate location-wise Final Accounts.
However the existing system is not meeting our requirement and we wish to operate thru one company code only.
Accordingly we plan to generate one more company code and migrate all the data from existing three company codes to this new one on a pre fix
cut off date. After that we will record all the transactions in this new
company code only and the existing codes would not be used further.
In this regard please advise us the steps required to be followed to migrate the  combined data of three company codes to one company code.
Kind Regards,
Sudhanshu

Answer 1

please find some info on SAP SLO
Sell-off of parts of the company
A company group sells the portfolio of one of its divisions to another company. As a result, the data that relates to the sold company division must be removed from the group’s SAP system, and transferred to the new owner.
With the "client separation” service, SLO offers two possible approaches to the solution. Either the data that the sold part of the company needs is migrated to a new client using one of the data transfer methods (Legacy System Migration Workbench or Migration Workbench), or a client copy is created for the sold part of the company, and the data that the parent company no longer requires is removed from the client copy using the SLO service "delete company code.”
Company merger
A company buys or takes over another company. The acquired company uses a different material numbering system than the buying company, for example. However, from the point of acquisition on, the same material numbers must be used, and it is therefore necessary to change the material numbers of the bought company.
With the SLO conversion service "material number conversion,” the material numbers of the bought company are changed so that they correspond to the naming conventions used in the parent company. This is done using the Conversion Workbench.
Reorganization/restructuring in the company
A company was previously organized according to regions, and based its SAP system on this structure. However, an analysis of business processes reveals that a central, function-based organization would considerably increase efficiency in controlling. As a result, the controlling areas used to map the structure of the company in the SAP system must be adjusted accordingly.
With the help of the SLO service "controlling area merge” and the Conversion Workbench, the old controlling areas, which were set up on a regional basis, can be merged into central units.
Optimization of business processes
In a government department, different standard charts of accounts are used for external and internal financial reporting. The duplicate work that this entails is becoming increasingly time-consuming and error-prone. The managers responsible decide that the external chart of accounts could also be used internally. As a result, the chart of account in the government department’s SAP system must be adjusted to reflect this change.
The SLO conversion service "chart of account conversion” makes it possible to rename or merge accounts and cost elements in the chart of account so that they meet the new requirements. The assignment table in which the changes are defined is retained in the SAP system after conversion for documentation purposes – for an external audit, for example.
