Use the Create part issue lines process to automatically add multiple issue lines for parts at once, for example, if you want to issue all parts for a particular order in one go. The lines created will be placed in the Part issues transaction file, and can still be edited before you process them.
It is also possible to add issue lines for parts by clicking on the Part issues form.
Note: Once you have checked the lines, process the issues by running the Process part issues process. The issues will not actually be posted before you have done this.
