Title: Problems with swap substitute part Post by Karen Mason on 01/12/04 at 07:54:15 I am not sure if my procedure is incorrect or if there is a programming logic problem. I use swap subtitute parts in the work order module quite often.  Usually, the item I am substituting is not on the swap substitute part list.  I get a message that asks if this is okay.  I answer yes.  Then in the quantity of the original material, I enter 0(zero).   The material in the work order shows only the substitute item. However, when I run MRP, a planned order is generated for the part I am manufacturing for a customer order and for the orginal material even though I already have a work order in existence for that part.   It is not a case of an additional order being placed by the customer.  There is only one requirement. I don't believe this was happening before but I'm not sure, as I have not been using the MRP for long.  Anyone else having this problem or know a solution?

Title: Re: Problems with swap substitute part Post by aricon on 01/12/04 at 10:26:22 The "problem" is that the MRP functionality looks at BKBMMSTR (the BoM master file) and then looks at WOBOM (the WO BoM file) so both requirements get represented.
