Multiple Predecessors receiving #REF

AOW0415

I am working on a timeline- making it go backward instead of forward (begin from launch day in order to see when the project should be started). Attempting to do multiple processors where I am taking the beginning date of one line and the finish date of another line minus X amount of weeks. I am getting a #REF on the first processor only...the second indicating "-Xw" is fine. There are not any circular references that I can see. Additionally, the first processor keeps removing my "SF" and reverting to "FS". Anyone have any ideas? Thanks, Amanda

Hi @AOW0415,

Only thing I can think of that definitely causes both issues you bring up is if you try to a parent row as a Predecessor. Is row 183 a parent row? If so, it will cause the #REF and will revert the SF to a FS.

Hi @Ray Lindstrom. Thanks for your insight. Line 183 doesn't appear to be a parent row. The line above, 182, is the parent row.
