Answer 1

Dear,
Try reversing the Credit memo first before the IR since this credit memo is depended on the IR posted against the GR. Or if this will not allow you, try creating a subsequent credit and then manually clear the document.
Use
When you post a credit memo, the system makes a number of checks:
The maximum quantity you can credit is the quantity that has already been invoiced. If you enter a larger quantity, the system issues the following error message:
Reversal quantity greater than quantity invoiced to date
If you post a credit memo for the same quantity as was invoiced so far, the system expects that the total amount invoiced so far is also credited. Otherwise, a situation might arise where you had no stock for a material but a stock value. If you do not enter the amount invoiced so far, the system automatically replaces your entry and proceeds to the item screen. A warning message informs you that your entry has been changed.
Reverse entry value set automatically for full reversal
If you post a credit memo for a smaller quantity than that invoiced to date, the amount of the credit memo cannot be larger than the amount invoiced so far. If you post a larger amount, the system displays an error message.
The system does not check whether your entries in the columns Amount and Quantity correspond to the purchase order price or invoice price.
Procedure
You post a credit memo as follows.
1. From the Logistics Invoice Verification screen, choose Document entry ® Enter credit memo.
The initial screen appears.
2. Enter the document header data and the allocation criteria.
3. Choose Goto ® Item list.
The item list appears.
The system lists the order items as per your allocation criteria. The items are not selected. In the columns Amount and Quantity, the system suggests the value and quantity invoiced to date for each item.
You can enter a different default logic in the Entry Profile.
4. Select the items contained in the credit memo. Check the quantities and amounts suggested by the system and make any necessary corrections.
5. Choose Continue.
The system then checks your entries and displays any necessary warning or error messages.
6. Choose Invoice document ® Post.
Result
The system posts the credit memo.
