When I try to generate monthly report for the last month, I wrote the DataLink formula as,
=PIAdvCalcDat("ct158","bom(bom('*')-1)","bom('*')","1h","average","time-weighted", 0, 1, 0,)
then I got the warning like,
The time is invalid
I realize the PE syntax may not be suitable here. (https://pisquare.osisoft.com/message/52412#comment-52412)
Could you please remind me of any approaches that I could get the DataLink Time syntax correctly for,
1, the first day of the last month;
2, the last day of the last month;
3, the first day of the last year;
4, the last day of the last year.
Thanks in advance!
