Hello! I'm new to the forum and Power BI so I thank you in advance for your patience with me.
I'm confused on how to implement this data merge. We get annual Page Hit stats from a portal vendor on a monthly basis and the layout of the Excel dataset is like this every month (please excuse the crappy table layout):
| orgid | orgname | groupnum | programid | programname | serviceid | servicename | m1 | m2 | m3 | m4 | m5 | m6 | m7 | m8 | m9 | m10 | m11 | m12 | startdate |

I'm still working on the data clean up, and there are more rows of data. Some records have null in the programid, programname, serviceid, and servicename collumns. The "m#" columns are the preceding months in the past year. For example, m12 is the month beginning with the start date, m11 the month before, etc. and m1 is last month (Feb 2022).
When I retrieve the dataset (same filename, same column names) next month, I want to import ONLY the m1 column but also making sure it matches up with the id fields so the values are populated in the correct groupnum, serviceid, etc.
Hopefully I've explained this one clearly as I'm really stumped how to implement this.
