The following example helps demonstrate what will occur when the "Prevent Negative Part Quantities" option is turned on:
If you try to disperse 100 parts in a work order, but only 60 parts were in stock, you will receive the following warning:
Then the system would automatically adjust the specified part quantity to 60.
If you use the Populate Material Units function in the Resources grid of a work order, and the specified amount of the material(s) exceeds the on-hand quantity, you will receive a warning (pictured above) and the system will automatically adjust the quantities to disperse the on-hand amount.
If you have default units for materials or fluids (setup in the PM/Template module or in the Work Flow Setup Tasks module) and the specified amount exceeds the on-hand quantity, the system will automatically adjust the part quantities to disperse the on-hand amount without giving a warning.
If you try to disperse parts in work order from out in the field and the specified amount exceeds the on-hand quantity, the system will disperse the parts anyway. This could result in a negative inventory. You will not receive a warning when this occurs.
