in the Validity from field. It is throwing an error as "Date cannot be shifted to 18/02/2021"
I can see the difference where in AUSP table for the unsuccessful case (Not allowing to change the future date) ECR is available with the relevant Master recipe, more than one ECR's are linked with the Master recipe where all are reflecting but for the successful case (allowing to change the future valid from date) ECR number is not available for the respective Master recipe in AUSP table.
So it is interlinked with class and characteristics also.
Could you please provide your valuable feedback for the above error to get it resolved
