In the MD05 Screen-MRP List
What is the significance of processing Indicator?

After the MRP run the MRP controller will check the results of the MRP process by seeing the exception messages (MD06) and take appropriate action to correct them. After correcting the exceptional situation he will switch on the MRP indicator.This MRP indiactor denotes that corrective action has already been taken...
Example: for the exception "start date in the past" for a planned order, he will change the start day as today. After doing this he will click the MRP indiacator box so as to differentiate this element from other unprocessed items.
