I need to create a matrix type calendar query that will replace rows that have zero value with 2 as the value in the summary column. This query is based on a file that runs monthly and daily. The file doesn't run on weekends or holidays. In my query, The max_month column values are compared with the summary column values. If there are missing months in the summary column than the missing values are replaced with zeros. The last step is to output the data set to a text file. My query isn't outputting any results.
In the attachment, there is a text file name tran_sumary and an excel file name month.xls. The tran_sumary file is a data file and month.xls is an example of what my query results need to print
