How to release retention amount under Purchase Order (which is deducted previously from invoices)?

[Vinnie]

Hi, 
In past we have deducted retention from invoices in line with contract. 
Now it's time for release the retention as work completed and accepted. 
How to release this retained amount under Purchase Order? 

Thank you and regards, 

Vinnie

i got the same question. i can't find the documentation how to release the retainer. this help page seems to suggest to create a credit memo once the supplier invoices the retainer. but it doesn't say how https://help.sap.com/docs/SAP_S4HANA_ON-PREMISE/c5b83a5abcff4efcb67a702ad5c71720/9cae7a1bf4834d91bfe...
