Labeler v7 will limit you to only being able to retrieve 10,000 rows. If you set it to 0, as directed in the Help document, it will set itself to 1, and if you set it to anything higher than 10,000, it will be reduced to 10,000. This is to limit the impact of connecting with QuickBooks and SQL databases that may have a significantly larger number of records than realized by the user.
To enable the Max Rows field to accept a larger number, browse to the program directory, C:\Program Files (x86)\Wasp Technologies\Wasp Labeler V7, and edit WaspLabelerV7.exe.config with Notepad. Change the value in this line:
<add key="MaxRowsCount" value="10000" />
to a number large enough to accommodate your records, for example:
<add key="MaxRowsCount" value="15000" />
Whatever value you set there will be the maximum the program will allow you to set in the Data Source window. Note: After editing the config file, you must also edit the data connection to show the desired number of rows.
