A 10 C 1
A 20 B 2
A 30 D 2
A 30 _10 E 1
A 30 _20 F 3
Above is an A material product BOM, how A calculated through serial number A eventually need 1 C, 2 B, 2 E, six F?
CodePudding user response:
Recursive algorithm,Multilayer order relation, until at the end of the loop through to order,
CodePudding user response:
"Parent" isn't this field should be recorded on the serial number of a layer of material, such as E and F "parent" should be recorded in the D, otherwise the superclass field meaning is less,If recursive by serial number, it will have to break up the serial number, will be in trouble,
