Functionality
This module is closely related to module BAPI_RPC_CALCULATE_PRICES forcalculating sales prices. Read the documentation carefully for theabove-mentioned module first.
As described in the documentation for module BAPI_RPC_CALCULATE_PRICES,this module can be used to structure a dialog process in an externalsystem for calculating sales prices. The calculated prices are, however,stored in a receiving SAP system. Every time moduleBAPI_RPC_CALCULATE_PRICES is called, a series of data from variousfunction groups is created and adjusted in the main memory of thereceiving SAP system.
To keep the external system independent of the inner status of thefunction groups, you can use module BAPI_RPC_REFRESH_CALCULATIONS. Bycalling this module, the memory areas of all the function groupsconcerned are initialized.

Notes
Every time this module is called, module BAPI_RPC_CALCULATE_PRICES iscalled after to completely restructure the pricing items required. Aseries of data recompiled by the database must be read.
For performance reasons, SAP recommends you do not use moduleBAPI_RPC_REFRESH_CALCULATIONS too often if it is not necessary.Generally, it is sufficient if you use the module at the beginning ofthe dialog processing for one-time initialization.
