How to set up the Process Chain Execution User
Even when the start process job scheduling in a process chain shows the name of the user that scheduled it, the user that executes the process chain is generally ALEREMOTE or whatever name is given to the batch job processing user.
To check which user is set up for a specific process chain, display it / or modify it in transactions RSPC or RSPC1, and execute the menu path Process Chain → Attributes → Execution User.
You can then select between using the BW Background User, the current user or a specific Special User.
This information is then stored in table RSPCCHAINATTR field BATCHUSER: if empty, it will use the BW Background User, if the value is %%actual%%, it means it will run under the current user, if it set to any other value, it will run under that specific user.
