Microsoft AX 2012 POS Issue Resolution

I need an expert to troubleshoot my Microsoft AX 2012 Point of Sale module. The system isn't automatically posting transactions or creating identifiers in the ledger. Currently, I am manually processing sales, which is time-consuming and prone to errors. I haven't attempted any solutions yet, so I'm looking for a professional who can quickly identify and rectify the problem, allowing for seamless transactions and accurate postings. Ideally, you have extensive experience with Microsoft AX 2012, particularly the POS module, and have a proven track record in troubleshooting and system optimization.
