Back in October I did an overview of the different ways to wait for a change in a SharePoint Workflow. You also have the option to wait for a certain time, there are two options which are waiting for a set duration or waiting until a set date. Either of which are easy to control or set. I am not focusing on these actions in this post, but just a quick note if you want the date to be dynamic when using wait until a date, then you will have to set the date you want in a workflow variable prior to setting the wait value. Otherwise your date is going to have to be static and that’s probably not going to work for you in 99% of your workflows.
Today, however I want to discuss waiting for a value to change on the list your workflow is attached to.
Bit of a disclaimer: Why am I still talking about SharePoint Designer? Why not Microsoft Flow? Don’t worry, I have some Flow blogs planned. However, Designer is still widely used and will be for some time. I encourage others to use flow where they can, but remember that not everyone has access to that yet. Designer is free and anyone with a SharePoint environment can make use of it. Hence, I still see providing insight and knowledge on this product very important.
I have a bit of a TLDR here as you may be just looking for the answer, and not WHY it is occurring. I strongly urge you to read the whole post to understand why things are the way they are and to make you a better person ;-p, but if you are in a hurry or think I talk\write too much, just click here to find out what you need to do.
