Getting the Next Voucher Number for a Payables Transaction Integration

At the beginning of the year, I wrote a 2-part series on retrieving document numbers assigned by Microsoft Dynamics GP when a field rule is set to Use Default in Integration Manager, see: IM – Retrieving document numbers assigned by Microsoft Dynamics GP when field rule is set to Use Default in Integration Manager – Part 1 IM – Retrieving document numbers assigned by Microsoft Dynamics GP when field rule is set to Use Default in Integration Manager – Part 2 Back then, I was addressing an issue faced by many working with integrations that require you to pass back some value to a source system and the complexities involved in retrieving those values, especially when the field rule is set to Use Default, this is, Microsoft Dynamics GP is assigning the field value, not the integration (via source file or otherwise). Today, I am looking at a slightly different issue, nonetheless, related. In this occasion, the client wanted to retrieve the next voucher number before hand for a payables transaction integration and assign it to the voucher number field, but did not want to have to write their own script.
