I am trying to receive parts from a PO and I am getting the error message "There are not enough component parts shipped to the supplier to receive this quantity.

I could see all the component parts of the particular line has been shipped to the supplier using supplier material functionality. 

The customer is using Project deliverables to create all the required supply request & the Component parts (2 parts ) for the line item are flowing from the Product item structure.

Had also tried this work around given below 

Check the PO Line you are about to receive.

RMB on the Supplier material (if the option is active and available)

One of the components which has fractional quantity per assembly probably has Qty Calc rounding of 0 in inventory part.

Change the Qty calc rounding and receive the PO Line

Still the issue persists , when I am trying to change the qty calc rounding to 1 for example , I am getting an error that Qty calc rounding must be zero for serial tracked parts ....How should I mitigate this error ? And how should I receive the remaining qts in the PO "There are not enough component parts shipped to the supplier to receive this quantity".

I have already posted same question for which i have mistakenly marked it as solved . Hence opening a new one . Expecting your expertise.
