Hi,
An EM attribute id is assigned to one of the EM objects EH- Event Handler Set, EV - Event Message, MS - Measurements and ST - Event Handler set.
Different types of EM Attribute ID's in system and which are fetched from below configs and tables:
- Event handler header - From table /SAPTRX/EH_HDR
- Event messages - From Table /SAPTRX/EVM_HDR
- Control Parameters - From config IMG -> Event Management -> Event Handlers and Event Handler Data -> Parameters -> Define Control, Info, and Rule Processing Parameters -> Control Parameters
- Info Parameters - From config IMG -> Event Management -> Event Handlers and Event Handler Data -> Parameters -> Define Control, Info, and Rule Processing Parameters -> Info Parameters
- System Parameters - From config IMG -> Event Management -> Event Handlers and Event Handler Data -> Parameters -> Define System Parameters
- Event handler status - From config IMG -> Event Management -> Event Handlers and Event Handler Data -> Statuses
- Tracking ID’s - Tracking ID from Table /SAPTRX/EH_TRKID and /SAPTRX/EVM_HDR
- Measurement - from Table /SAPTRX/EH_MEASR
- and more...
For example - If you have defined Container type/Freight booking Type/ Dates as System parameters or Control Parameters from above config, then it shows SYST_ZCONTAINER_TYPE / SYST_ZFRT_BOOKING_TYPE / SYST_ZCONT_CHECKIN_DATE or CNTR_ZCONTAINER_TYPE / CNTR_ZFRT_BOOKING_TYPE / CNTR_ZCONT_CHECKIN_DATE. Once you define these configured fields, then these will be visible in IMG -> Event Management -> Event Messages, Status Queries, and Web Interface -> Web Interface -> Define User Profiles -> Selection Profile and assign it in your existing selection profile under "Selection Profile Details".
Note: Do not define more than one control parameter in Selection Profile as this may impact your system query performance. To know more, you can check this SAP OSS note 1260125.
Now go to SAP EM WebUI and you can see these selection fields in your tracking scenario.
