Exclude Reservation stock type from MRP Run

[Former Member]

Dear All,

I need to exclude Reserved Stock Type from MRP Planning.

Please guide me with the steps to perform the above.

Just for your information, the reservation is coming from Plant Maintenance module, not Production Planning.

I tried changing the Availability check 02 - PM checking rule to exclude reservation, but it doesnt seem to work. Maybe i did it wrong.

Please help.

Hi,

Note MRP type in MRP1 view of concerned material master.

Go to Tcode - OMDQ and Check settings for this MRP type.

Indicator PM/ntwork Reserv. might be ticked for this MRP type, due to this PM-Order-Reservation Qty

is considered in Calulation of PR/ Planned Order Qty during MRP run.

Hope this helps,

Regards,

Rahul

Nazrin,

Availability check configuration (OVZ9) has no impact on MRP. MRP relies on its internal rules when it is performing its net requirements calculation. You have very little control over which elements are included/excluded.

You can exclude selected storage locations from MRP planning. Stock and reservations against these storage locations will therefore also be excluded.

You can exclude a material from planning, change the material master MRP type to ND.

Your best bet, though, would be to set your PM planning process up such that these materials never create the reservation in the first place.
