Item extended descriptions with commas cannot be imported from a tab delimited (CSV) file. Use temp variables to create the commas from the source file.
Note: Similar steps can be used for quotation marks ("").
In the source file, change the commas to asterisks (*).
In Sage MAS 90 or 200, expand Visual Integrator and Main. Double-click Import Job Maintenance.
Select (or create) the import job for IM.ITEMEXT, and click the Data tab.
Add the following fields to the selected fields list (below COMMENT_TEXT):
TEMP01:
Type = String
Operation = String
Default value = * (asterisk)
TEMP02:
Type = String
Operation = String
Default value = , (comma)
TEMP03:
Type = String
Operation = Replace
Field = 3 (Description)
Length = 9999
Move the COMMENT_TEXT field to the bottom of the list.
Double-click the COMMENT_TEXT field to open Import Field Properties, and make the following changes:
Operation = Calculate (from Replace)
Calculation = SUB({TEMP03},{TEMP01},{TEMP02})
Run the import job.
