I try to match the sales to the date they enter the system. However, it is not always filled and in that case I want to take the invoice date. This one is also not always filled and in the latter case I want to take order date. My question: How can i do that (in this order)?
Now I have read something about switch case but not enough to apply it. can anyone help me with explenation or an example?
But it seems that I will get another problem. Invoice Date is sometimes (by default) filled with 01-01-2017 and I think that is not recognized by if (alt). if (alt) will choose the 01-01-2017 date I think. And what I want is that I can also filter this
