Re: Available to Promise

The calculations that are in the guide have a recursive loop.

RSI = Demand - FUD
FUD = next day's RSI

Here is the exact text from the manual:

Required starting inventory (RSI): Demand minus supply plus the future unmet
demand (FUD). This is the amount of inventory needed to meet a specific
days demand plus any shortage in coverage against future demand. The
calculation for RSI for a day is demand minus supply plus FUD. The RSI a day
is the FUD of previous day.

Future unmet demand (FUD): The amount of demand that is not covered by
supply in future days. For a specific day, FUD is the RSI of the next day.

We seem to be having a problem with the Available To Promise. Does anyone
have the calculation formulas? There used to be an excel sheet on infor365,
but the link is broke.
