Microsoft Great Plains is one of three Microsoft Business Solutions mid-market ERP products: Great Plains, Solomon, Navision. Considering that Great Plains is now very good candidate for integration with POS application, such as Microsoft Retail Management System or RMS and Client Relation Systems, such as Microsoft CRM – there is common need in Great Plains customizations and integrations, especially on the level of MS SQL Server transact SQL queries and stored procedures. In this small article we’ll show you how to create auto-apply utility, when you integrate huge number of sales transactions and payments. We will be working with RM20101 – Receivables Open File and RM20201 – Receivables Apply Open File. Let’s see SQL code:

declare @curpmtamt numeric(19,5)
declare @curinvamt numeric(19,5)
declare @curpmtnum varchar(20)
declare @curinvnum varchar(20)
declare @curinvtype int
declare @curpmttype int
declare @maxid int
declare @counter int

-- Create a temporary table

)

create index IDX_INVNUM on #temp (INVNUM)
create index IDX_PMTNUM on #temp (PMTNUM)
