We are working on the migration from the old way for transferring data of Personnel Time Events (transceiver) to the new HR PDC ( BAPIs ) technology.
We´ve done the configuration in SAP and now we want to start the testing phase. What kind of program or application need to be implemented in the external system or server in order to make the link between SAP and the external data? We know that SAP will send and receive IDocs. The supplier will configure their system in order to send the data with the structure that we need. Now we need to know how the exchange of information occurs.
Thanks for the help.
