As mentioned in Event-Based Revenue Recognition - Projects

Change of the revenue recognition key is possible only if atleast one of the following is true: 

• No postings have been made. There is possibility to change the revenue recognition key to any revenue recognition key within the same revenue recognition key area.

• In case any posting has already been made:

  • There is possibility to change the original revenue recognition key to a new revenue recognition key if the allocated assignment rule is equal to the original revenue recognition key.

  • There is  possibility to change the original revenue recognition key to a new revenue recognition key within the same area if the assignment rules are not equal, but the assigned G/L accounts are equal.

Make sure the project fulfills above 2 conditions when postings already been made.

When there are no posting to project, it could happen that it is unable to choose other key to change, since there's no other keys available in the search help, the reason is that other keys are not compatible based on above 2 conditions.
In this situation, change can be done manually by typing specific RA key (CASE SENSITIVE) into dialog box for key change and press save.
