Requirement: End User wants to see parcel tracking events via an App or External webpage. Password has an expiry date, End User can request a new password.
There are many abap password generators available.
I was thinking of storing the password and expiry date as control parameters.
User app (or portal) would call /SAPTRX/BAPI_EH_GET_DATA with the EH details and Password.
If the password has expired, the user would send an Event Message to generate a new password.
I don't think EM Authorization or Tracking-ids with validity dates would work fir this requirement.
Any tips or ideas?
