I am attempting to automate a process using modelbuilder. The workflow is as follows: A calculate field is run on an input dataset parameter, then a SPATIAL JOIN is applied to the output. This part works properly. However, Then I want to run an APPEND on the output of the spatial join (AKA, Parameter (3)). However, one of the fields I am attempting to append is linked to the spatial join preceding step; each time the appended field presents itself as INPUT_AddSpatialJoin_#, where the # corresponds to the number of times I have run the spatial join process within the process. This creates an issue as this model will need to be run on a weekly basis, and each time the # value will change and not append properly. A similar issue occurs if attempting to use a fieldmap file for this process, as it uses the outdated # value. Is there a way to work around this, such that the _# can be eliminated from being added to the AddSpatialJoin append field?
