Use
You can use this enhancement to change the save type of encrypted payment card numbers within the framework of the POS inbound.
The SAP system references encrypted payment card numbers with a reference to a GUID. This is issued during the encryption process. For reasons of performance, two different save types are possible:
1. You can use the same GUID (the same encryption entry) for the same payment card number.
2. You can use a new encryption entry (new GUID) for the same payment card number.
This enhancement is relevant within the framework of encrypted saving of payment card numbers on the IDoc database table.
Requirements
The global security settings for payment card processing must be active (table TCCSEC). In addition, the business function ISR_APPL_PCI_DSS and the POS inbound-specific implementations of the following enhancements of the IDoc basis must be active, to enable encrypted saving of POS payment card numbers on the IDoc database table:
1. Encryption before saving
Definition name: IDOC_DATA_MAPPER (classic)
Implementation name: IDOC_PCI_ENCR_IM
2. Encryption after reading
Definition name: IDOC_DATA_CRYPT (ES)
Implementation name: IDOC_PCI_DECRYPT_IM
Standard settings
As standard, the same GUID (the same encryption entry) is always used for the same payment card number. You can override this setting using the enhancement.
