Hi,    I have a table that has Prod_Ids (product avail to sell) and Start_date and End_date. I would like to group similar Prod_Ids for each day ... essentially creating a count of Prod_Ids (product) avail to sell each day. For example, Prod_Ids = 1011111, Count = 50, Start_date = 01JUN2020. So I am also changing the datetime to date9.    My key question is how to count the Prod_Ids for each day to create a daily count of product Prod_IDs.  Here is an example of the data:    Prod_Id Start_date End_date 10644800 26FEB2020:04:05:50.180000 27FEB2020:04:25:54.189999 10656210 02SEP2019:04:15:36.840000 04SEP2019:04:03:47.819999 10656210 07MAR2020:06:25:11.780000 08MAR2020:06:37:29.919999 10656210 17FEB2020:03:55:08.130000 18FEB2020:04:58:05.809999 10665400 21AUG2019:12:44:09.780000 24AUG2019:05:16:01.809999 10665400 06NOV2019:05:51:53.420000 11NOV2019:05:14:50.279999 10682600 27FEB2020:04:25:54.190000 28FEB2020:04:25:13.529999 10703611 29SEP2019:04:04:38.320000 30SEP2019:05:19:45.929999 10703611 15DEC2019:04:12:49.910000 21DEC2019:04:40:18.419999 10703611 16NOV2019:05:19:58.700000 17NOV2019:04:43:56.199999 10703611 21AUG2019:12:44:09.780000 24AUG2019:05:16:01.809999 10703611 06NOV2019:05:51:53.420000 11NOV2019:05:14:50.279999 ...
