• SAP Tcode: BNK_SET_HMAC_KEY - Set HMAC Key

  
  Overview:
  BNK_SET_HMAC_KEY is a transaction code used in SAP systems to set a HMAC (Hash-based Message Authentication Code) key. This key is used to authenticate messages sent between two systems, ensuring that the message has not been tampered with or corrupted during transmission. 
  
  Functionality: 
  The HMAC key is used to generate a digital signature for each message sent between two systems. This signature is then compared against the signature generated by the receiving system, and if they match, the message is authenticated. This ensures that the message has not been tampered with or corrupted during transmission. 
  
  Step-by-step How to Use: 
  1. Log into your SAP system and enter transaction code BNK_SET_HMAC_KEY. 
  2. Enter the HMAC key you wish to use for authentication. 
  3. Click “Save” to save the HMAC key. 
  4. The HMAC key will now be used for authentication when sending messages between two systems. 
  
  Other Recommendations: 
  It is important to keep your HMAC key secure and only share it with trusted parties. It is also recommended that you change your HMAC key regularly to ensure maximum security.
