AMI: Step 8: Advance Metering Infrastructure of Capability Activation Group (AMICAG)

1. Go to SPRO -> SAP Utilities -> Advanced Metering Infrastructure -> Basic Settings -> Define Activation Groups for AMI Capabilities
   
2. The purpose of this configuration is to define activation group that can be used to activate or deactivate AMI capabilities of a meter independently of the capabilities of the corresponding AMS (Advanced Metering System) and AMCG (Advanced Meter Capability Group). This is an optional field on meter.
3. Enter "Activation Group Name" and its description.
   
4. Select "AMI Capabilities for Activation Group". Assign AMI capabilities to the activation group
   
5. Note: AMS and AMCG must support the capabilities as well if you need to turn on the capabilities in activation group.

AMI: Step 7: Determination Group of Advance Meter Capability Group (AMCG DG)

1. Go to SPRO -> SAP Utilities -> Advanced Metering Infrastructure -> Basic Settings -> Define Advanced Meter Capabilities
   
2. Select "Determination Group of Advance Meter Capability Group (AMCG DG)". The purpose of this configuration is to determine advance meter capability group. It is assigned to device category, and if default AMCG is selected, it will be assigned to AMI meter during meter creation.
3. Enter "Advance Meter Capability Group Determination Group Name" and its description.
   
4. Select "Advance Meter Capability Group of a Determination Group (AMCG DG)". Assign "Advance Meter Capability Group (AMCG)" to this determination group.
   

AMI: Step 6: Capability Group of Device (AMCG)

1. Go to SPRO -> SAP Utilities -> Advanced Metering Infrastructure -> Basic Settings -> Define Advanced Meter Capabilities
   
2. The purpose of this configuration is to group functions of a device
3. Select "Capability Group for Device". Enter "Advance Meter Capability Group" (AMCG) Number and its description
   
4. Select "Capabilities of Device". Assign "Advance Meter Capabilities" to this device.
   

AMI: Step 5: Advanced Metering System of a Determination Group (AMS DG)

1. Go to SPRO -> SAP Utilities -> Advanced Metering Infrastructure -> Basic Settings -> Define Advanced Meter Capabilities
   
2. Select "Advanced Metering System Determination Group". The purpose of this configuration is to group AMS system, this determination group is assigned to device category, if default AMS is selected, it will be assigned to AMI meter during meter creation.
3. Enter "AMS Determination Group Name" and its description.
4. Select "Advanced Metering System of a Determination Group". Assign AMS to "AMS Determination Group".
   

AMI: Step 4: Advance Metering System (AMS)

1. Go to SPRO -> SAP Utilities -> Advanced Metering Infrastructure -> Basic Settings -> Define Advanced Meter Capabilities
   
2. Select "Advanced Metering System". The purpose of this configuration is to define system that AMI meter is connected in the advanced metering infrastructure.
3. Enter AMS system name, validity date, description of the AMS system, MDUS that it is communicating to, and the capability group of AMS
