Excel/Reference Sheet Linkages


I am working on two files at the moment:
1. Control File
2. Data Model

Control File has raw data input while Data Model has formulas linked from Control File. e.g. =SUM([Control File]Weekly Data!$B$2:$D$2) or =SUM([Control File]Weekly Data!B4:D4).

I primarily work on the Data Model everyday and the Data Model file is updated on a weekly basis. The issue arises when the Data Model file is NOT OPEN and I add weekly data to the Control File. While I am doing that, I sometimes have to add rows for a new field. That new field moves the below cells lower to another row and I save the Control File. Later on, when I open my Data Model file, the formulas linked to the Control File are disrupted for the ones which were below the added field. This disrupts my Model of the entire analysis.

Please suggest some quick solutions to it. I am running short of time to deliver an analysis and would appreciate all the quick help that you can provide.


Use defined names. For example, name the range B2:D2 as Range1 (or something more meaningful). in the Data Model, use =SUM('[Control File]Weekly Data'!Range1). If rows have been inserted in the control file, the range1 name will still reference the right cells.
