Transactional Infocubes are used for SEM.. and are meant for
Read. Here is the documentation from SAP Help to convert a standard cube into transactional cube when it has
data:
Conversion with
the Loss of Transaction Data
If the standard InfoCube already contains transaction data but you no longer need it
(for example, test data from the implementation phase of the system), you proceed as follows:
In the Edit InfoCube
screen of the Administrator Workbench , choose InfoCube ® Delete data content and confirm the subsequent confirmation
prompt.
The transaction data is deleted and the InfoCube returned to the status "inactive".
Then proceed the same
as when creating a transactional InfoCube.
This procedure is also suitable to convert a newly created InfoCube
(for which no transaction data is yet available) into the other type, if the wrong setting was chosen by mistake when it was
created.
Conversion with the Retention of Transaction Data
If the standard InfoCube already contains
transaction data from the productive operation, which you still require, then proceed as follows:
In the ABAP
Workbench, start the program SAP_CONVERT_TO_TRANSACTIONAL.
In the following screen, enter the technical names of the
InfoCube which you want to convert into a transactional InfoCube.
Choose Program > Execute.
