How to Fix this error:-4014 Cannot add row without complete selection of batch/serial numbers

Question

I'm encountering an issue in the SAP system, specifically when attempting to update the bin location. I'm getting the error code -4014, which says, "Cannot add row without complete selection of batch/serial numbers." This error occurs when I scan the bin, batch, and quantity in the FE (Front End) and try to submit the information. Below is the relevant code:

I'm not very familiar with the SAP system, and I'm seeking assistance in resolving this error. Specifically, I'd like to understand why the bin location is setting to null or zero in SAP. Any guidance on how to correct this issue would be greatly appreciated.
