ALL: I have an idea for managing data input based on a matrix of 4 dimension intersections in a module, based on a trigger boolean stored in a like module. My question is simple; Is it possible using any function (known or unknown) to use a formula in the module, to check the boolean intersection of a second module to verify that the intersection is approved for entry? so it might be: For line item XYZ, IS ISACTUAL VERSION ACTUAL.MODULE, ELSE IF IS MODULE.MATRIX="FALSE",0, ISINPUTALLOWED. I realize that this may not be needed, but trying to find ways to control data options for adding input versus pulling data from other sources or setting the value simply to zero, or locked. Thoughts, Thanks. Petar
