I have a project where I am setting a range of production dates and want the sheet to auto-update if I update that there is slippage in the timeline to see how far out things push.
It is easy to schedule dependencies on the front end. For example - if I have items:
1. PO to readiness of raw materials is 2 weeks from the PO - but we have a hypothetical 8 weeks of production
2. That raw material ships for 3 days
3. It takes 2 days to put into inventory
4. Then it goes into production
I use the SS (Start to Start) dependency and have the timelines structured that it cascades as described above. That works fine if everything is static.
If raw material is not available and not that 8 weeks becomes 9 weeks, then items 2-4 need to extend out the additional week.
I tried to use a formula in the date column to account for this (set dates in item 1 and use a forumla in 2-4). I could get this to calculate in any other column except for the date colum for end-date.
Does anyone have an idea of how to set this constraint and if it is even possible?
