On only the text run of this series, at the third Column Aggregator node (761) numbers appear at the end of my aggregated columns–but only 8 of 9 columns. These numbers are not part of any data in the system, don’t relate to any IDs I am using, and do not add up to any sum within the data. (see (1907) and (2090) in row0 and row8)
I am simply using a unique concatenate with count function in the Column Aggregator. And again, I use these exact same steps in a separate run with just my own numeric identifiers without these numeric aberrations appearing.
that is count of empty cells in a row. You can use toNull($$CURRENTCOLUMN$$) expression in String Manipulation (Multi Column) node to replace empty cells with missing value so Column Aggregator can deal with them.
Hi Zack, placing string manipulation multi column before the column aggregator that was producing the errant results actually deleted all of my unique concatenate results from the prior node. so i ended up removing the string manipulation “null” function to get back to where i started. thanks
not sure I follow. Function I recommended to use, toNull(), from String Manipulation (Multi Column) node should only replace empty string column with null i.e. missing value thus every other count should stay the same. Having missing value instead of empty string should solve your issue with numbers appearing at the end of aggregated column. However this might impact other downstream manipulations you got so either you can revert to old after Column Aggregator or modify workflow accordingly.
