Return invoice / credit memo generation wrong dates

Hi,

We are facing one issue now a days that in return invoice / credit memo generation dates. system takes wrong date for credit memos either future or past date instead of actual credit memo / return invoice date.

For reference please view the attached excel sheet.

        

Type	Branch Name	Order Number	Order Date	Invoice Number	Invoice Date	Receiving Date	Status
Referenced order	ISD Riyadh	50270	4-Nov-15	215234321	4-Nov-15		OK
Return Order	ISD Riyadh	50309	8-Nov-15	215730062	9-Nov-15	08-Nov-15	Return Invoice Date Should be 8-Nov-15
Referenced order	ISD Yanbu	53053	3-Nov-15	215250720	3-Nov-15		OK
Return Order	ISD Yanbu	53069	5-Nov-15	215750029	3-Nov-15	05-Nov-15	Return Invoice Date Should be 5-Nov-15

This issue occurred after application up gradation from 12.1.1 to 12.1.3. Before system was generating the credit memo's with actual date when the return order gets closed. But now it's generating wrong date for credit memos.
