| Hi Sanjeet, Investigation show there are two specific issues causing this: - Delay in SDC process is causing the transaction save process to lock records for a long time
- SDC server response issue.
Issue 1 - We are looking into what can be done to work around the SDC processing. Issue 2 - See attachment showing that the SDC call and status is correct on the POS side. Please log this issue with the SDC provider. Refer to Attachment name: SDCServerResponseIssue.txt Regards

| To resolve issue 1, we have moved the "Get Next Invoice Number" and "Validate Invoice number" out of the POS Transaction save routine. This means that if a Transaction Save fails, the Next Receipt number will be lost. We have tested this in 9.4 and will be preparing for UAT shortly. Regards

| --- Response from Taxcore support --- Dear Sanjeet Prasad,Hi,
Both request examples are correct.
Please note that TaxCore Support can support you with virtual SDC environment. For production ESDC please refer to your ESDC vendor.
From our experience, this can be related to: - uninitialized E-SDC (tax rates and other information is not downloaded from Internet or thumb drive)
- network connectivity between POS and E-SDC, usually caused by firewall or anti-virus software
- wrong smart card (staging vs. production)
Your TaxCore Support Team,
Support Department

The following were done to verify: - Manually introduced 10-second delay in processing sales
- Connected 3 POS terminals and completed sale at the same time
- All 3 machines completed sale successfully.
