- MD01 is generally used to run the MRP for all the materials in a plant normally just<br />

before go-live.<br />

- MD02 is used to run MRP for materials which have a BOM i.e multi-level.<br />

- MD03 is used to run MRP for materials which do not have a BOM i.e single level.<br />

<strong>SAP</strong> Factory Calendar<br />

Factory calendar contain company specific dates such as alternate working Saturdays,<br />

Plant shutdown etc.<br />

You can create your company factory calendar via transaction code 'SCAL'.<br />

Assignment of the factory calendar by plant is done in transaction code 'SM30 -<br />

V_T001W'.<br />

An example of a <strong>SAP</strong> application that uses the factory calendar is the <strong>SAP</strong> MRP modules.<br />

Assuming that you have a specified an alternate working Saturday, MRP will postponed<br />

the planned orders to the next working day if it happened to falls on a non-working<br />

Saturday.<br />

GR processing time in PP and MM<br />

I have one material number that is procured externally but also produced inhouse.<br />

Now I have one problem with the GR processing time. As far as I can see the<br />

parameter on the material master on MRP2 view and Purchasing view is the same<br />

(MARC-WEBAZ). But in my case the GR processing time should be only used for<br />

goods receipts in MM (from purchase oders). This GR processing time must not be<br />

added to my lead time scheduled in production (when producing the material). How<br />

to solve this conflict?<br />

We have a make to order enviroment, that means our production orders are created<br />

(and scheduled) directly from the sales order. The sales gets back a confirmed date<br />

and quantity from production order scheduling - and here this GR processing time<br />

is also added. Absolutely useless in this scenario, but MM needs this GR processing<br />

time for the external procurement of the material.<br />

I'm hearing at least two problems here. Let me lumber through them as I see them.
