My apologies for asking the obvious ... you are remembering to change the filter at the top of the screen from PO to SO or WO?

Yes. LOL, it's ok to ask. Someone else prior to me set up our system, and I've gotten most of the glitches out of it to set it up appropriately, but this is really frustrating.  We just implemented MRP and are trying to make sure we have a full work through on everything, but it seems some things just aren't working the way they are supposed to and I have a feeling it's a set up I just can't locate. 

Here's the main screen..shows that we have 10 Req for a WO.

Here is the work order field, and yes, I made sure the filter says all, so there is no date applied to it.  Not clear why it's empty.  The sales order one is too.  

Req for WO is not the same thing as On WO.

Typically in our world, it should either show up on a W/O or a sales order, so REQ or Required for WO would be the same as ON Work order.  If it's not, please explain, because I guess maybe that's where the confusion is.  

OK ... so do you have any evidence other than the data on the main screen that these items are really on order? Sometimes those numbers on the main screen get screwed up & can be fixed by rebuilding the sort files. I rebuild all the sort files once a month, whether I think I need to or not. This can be found in Library Master/Utilities. But I caution you to be very careful with the utilities in here -- you can really screw things up. You may want to chat with your reseller first.

I do have the evidence, I just ordered them yesterday..It's the top line item.  We were testing the MRP, and trying to link the S/O, W/O and Item maintenance together to flow through to MRP better, and realized that the item Maintenance function (tab 1) now DOESN'T work.  Tab 6 in item maintenance has only ever been able to show us what was on PO's, never gave us accurate S/O or W/O information-not sure why.  Which we would like to figure out.  I THOUGHT the fix would be to include all of the information on the right in the PO entry fields that you see here.  W/O, S/O, etc.  It didn't help AND it now removed all that information from the quantities area of tab 1 in Item maintenance.  WEIRD right?! 

Req for WO means it is being used in a WO as an ingredient, and it will not show up on tab 6.

On WO means it is being produced in a WO, and this type will show up on tab 6.

Ahhh, I see.  Does having Bill of Materials fix this, or make it work better I guess is the question?  

We don't use work order or MRP, nor do we reference sales orders on our POs.  I've never had issues with the sales orders not showing up on tab 6 & the only problems I've had with incorrect data showing on tab 1 are cleared up by rebuilding the sort files. We do use bill of materials, though, and I would not expect it to fix any of the problems you are describing.

An item On Work Order means that it is being produced as a result of a work order.  Required for WO means that it is a component on a work order.  There is no way that an item would be the same.  For example if you had a valve on a work on and the parts are body, ball, stem, end.  The Valve itself would be On Work Order while the ball and stem would be Required for Work Order.
