Hello Tonya,
You cannot create versions for appropriation requests. Instead, you can create any number of
appropriation request variants.
You can assign one version to each appropriation request variant. Using this method, you can link each different variant for planning or implementing the appropriation request to a given version.
You make this assignment individually for each appropriation request.
Please refer version in Investment Management at below mentioned pdf for more details.
