Hello community,

I am trying to write a python script comparing two saved cases using the DIFF API.

psspy.asys(sid=0,num=1,areas=99)

psspy.diff(sid=0, all=0, apiopt=1, status=[],cfile = compfile)

Subsystem identifier 0 is defined for Area 99 for the case comparison.

I received an error message as shown below:

Messages for api DIFF

Invalid SID value or subsystem SID is not defined: 0 (001382)

Can anyone help with this error? Thanks!

I believe you need to first initialize the area subsystem 0 with psspy.asysinit(0)

Thanks for the reply. It is a mistake that I should use BSYS instead of ASYS as I am comparing the buses in the DIFF API.
