In a model I'm working on I need to use the post function. When I put it by itself in the formula it works fine. But since I only want to use it when a certain condition is met, I changed the formula to: if NOT lineitem then 0 else post(x,y). With this syntax, all I get is 0s. Is this a known issue?
I figured out the issue. The POST is working but I have think about my condition. The way I have it now, if the condition is satisfied in week1 but not in week2, the formula in week2 override the posted value with 0. Thanks for your help.
