Hello,

Using PB 2022 R2 build 2819

Need to know whether any limit is there to export data from a datawindow / datastore to JSON.

Command used to export:

ls_json = dw_1.ExportJson(False)

Data in the above datawindow is retrieved by entering a period.  Data is retrieved for the given period.  If we give a whole year, then we get empty string in ls_json [ when I try to write the json to a file, I see an empty file, with no content ].  If the period is shorter, then we get a perfect JSON string.  

For one year, there are 117345 rows with 21 columns.  

Since this works for a shorter period, I suspect there should be some limit.  

Any idea?

Happiness Always
