Actually this division will lead to problems.
Example, I purchase 50 Bundles totalling 493 Kgs.
The conversion factor is 0.101419878 = 0.10142 rounded off to 6 decimal places (which is the maximum supported by SAP)
SAP multiplies 0.10142 * 493 Kgs and gives the result as 50.00006 Bundles. Since we activates 6 decimal places for Quantity, the 6 decimal places are getting activated for Bundles also!
