I’m working in a business process where a sales orders requirement date should never be transferred to MRP with the original customer’s requested date.
Example: at the time of order entry ATP bounces the requested delivery date, since product is not available at the time. The system suggests a new date for confirmation. The customer at this time has the option to agree to the new proposal or a sales order will not be entered. I want this new committed date transferred to MRP.
To do this I select the ‘Fixed date and quantity’-indicator in the Schedule lines tab in VA01. As in my case this should always be the case, in customizing I choose this as a default setting for the specific SalesArea (IMG > Sales and Distribution > Basic Functions > Availability Check… > Availability Check > Availability Check with ATP… > Define Default Settings)
Without setting the indicator you are basically suggesting that production can still catch up with this additional requirement and the customer’s original requirement date will be transferred to MRP. See also SAP Help.
