Process variable size limit is 101?

Question

Hi guys, 
 Is there a new limit to how many rows can be stored in a process variable that is marked as multiple? I made a query that returned 146 elements and the length of the ac!variable is 146 but in the pv!variable there are only 101 elements. Everything after the 101st element seems to have gotten trimmed out.

Are you talking about the actual data array size stored in the PV, or the size of information Appian will display in the UI before truncation? AFAIK these are two different things. And just because the information displayed in the GUI is truncated does not mean the data itself has been truncated - to determine that you'd need to call length() on the variable (in process) and look what the output is, and/or feed the PV's value into an interface and display it in a paragraph field / grid / etc (something where you're able to fully judge the size of the data contained therein), or one of another methods. Viewing the process instance "variables" value and/or the same in Process History is not necessarily a method guaranteed to show you the full contents of a data-heavy variable.

 Yes the Process History tab 'truncates' your large data sets, but the Variables (actual data set) will not. That screen shot is the key - check the Variables tab as well
