What is the difference {mfselbpr.i} and {mfselprt.i}

[skunal]

What is the difference {mfselbpr.i} and {mfselprt.i} can anyone please help me on this difference

 

[mosfin]

{mfselbpr.i} in addition to output field, allows input of batch id (for running the report later as a batch)
{mfselprt.i} asks only for output, i.e: no batchID option
