in the Business One 9.3 PL: 07 32-bit and 64-bit Client I've found the following error: If you add a new ItemWarehouseInfo with an empty warehouse code to an Items object of the SAP Business One DI API 9.3, incorrect data records with a strange ItemCode are added to the table OITW. The error occured during the exection of a coresuite customize optimizer rule.
Business object: Items
Child object: ItemWarehouseInfo
Database Table: OITW
Database Columns: ItemCode (PK, nvarchar(50) Not NULL), WhsCode (PK, nvarchar(8) Not NULL)
The used operating system is Windows 10 and the database system is Microsoft SQL Server 2016. It would be nice to fix that error soon.
