Customer implementation for Tax calculation
We have a requirement in which we are connecting a new client to SRM system. Now the issue is that the SAP backend does not have any taxware or related softwares to calculate tax. This is for the Canadian region. We are in the classic scenario and hence the FUNCTION BAPI_PO_CREATE is called while PO creation if I am not wrong. Now we need to identify the user exit where the customer could write his custom code for determination of the tax for the Canadian region. Could you help me with any document used for implementing such a scenario and in the identification of the user exit and the concerned function where we need to make change for incorporating customer logic?
Awaiting your reply !
