Hello @Cowboy13, great question. You absolutely can delete optional columns. However, some of those columns are used in Community Templates so be aware that those reports might be affected by your deleting or renaming optional columns.
You must not change the names of the headers for the Date , Description , Amount , Account , Account # , Institution , or other core data columns. Additionally, the name of the Transactions sheet itself must not be changed
As per my original post, It would be helpful to have up to date sheet like the one in the link I shared so people know which columns are required, which ones are optional, which ones are automatically included vs added by users, etc. This will help me and others when we create templates.
I ran into this recently as I had forgotten I must have added Category Group to my Transactions sheet a while ago and I assumed everyone had this column. So, my template did not work for those who didn’t. I needed to update my shared template to take this into account, but It took my a while to figure this out.
These are Tiller’s officially documented columns Transactions Sheet Columns | Tiller Help Center and is kept up to date. The other sheet is a community resource and not something anyone is montioring/updating.
No issues removing either of those columns except if you’re using AI Suggest. AI Suggest uses the Full Description column for the 2nd stage description matching algorithm.
