Answer 1

I think it means that..
if there are distributed processes in a chain..(example is loading process)..then the starting background process keeps on polling(or checking) the system for completion of other processes and does not get released until other processes(in other sessions) are complete.
See help text from system..
The main process waits until other proceses have finished
Use
If the chain contains distributed processes (for example, a loading process) you use this indicator to specify whether you want to hold back the starting background process until the actual work process is complete in other internal sessions, or whether you want to release it immediately.
Setting the indicator has the following advantages:
External scheduling tools that react only to the SAP internal event 'Batch Process Complete', are also informed about the status of distributed processes.
Very secure process runs. The starting background process asks about the status of the current processes every two minutes (polling).
Setting the indicator also has the following disadvantages:
Increased demand on resources. Although the CPU is not under pressure during the waiting time, it is during the status checks that run at two minute intervals.
You require one more background process.
Note:
If you implement a distributed process and want to use this indicator, implement the interface IF_RSPC_GET_STATUS and refer to the documentation for the HOLD-Indicator.
