Continued to test the application to check if the printing will not be encountered an error, the printing testing is by debugging only as no printer is used yet. As per checking, an error was encountered when checking the printing, I modified the application to fix the error encountered in passing the data to be printed. Tested the application again, and as per testing, a problem is encountered, when saving the last SKU and qty printed before clicking the pause button also the printing is too slow as for loop is added. Checked and fixed the error in the printing, might as well change the approach on the saving of SKU and qty when the printing is paused. The checking and testing will continue tomorrow. While checking of the data as well, found out that there is a duplicate SKU displaying in the grid, as per checking, the cause of this is the IBHAND field from invbal table. This need to be asked from sir Rey.
