When I said 'what is RLD date' I meant "what is 'RLD' an acronym for". This is not a standard SAP acronym/abbreviation.
RLD = Request delivery date
You earlier stated that both material masters were the same. Now you are saying that one is MTO and one is not. Can you please elaborate?
In both cases we are using MTO only, but what I'm saying if I change strategy to 40 (MTS) for first case then even in first case ATP confirm order on requested date.
I don't see any issue with factory calendar reason is if I change material strategy to MTS then ATP confirm order on requested date, but if I keep strategy to MTO then ATP delay with 1 date.
Example:
Case-1:
Plant-1, Material-1, MTS scenario - ATP confirm sales order on requested date
Plant-1, Material-1, MTO scenario - ATP confirm sales order with 1 day delay on requested date
Case-2:
Plant-2, Material-1, MTO scenario - ATP confirm sales order on requested date.
In above both cases material master MRP view setting, BOM, routing, transit time are same.
