Strategy 74

Hi experts,

I have a FERT which is made of HALB1. HALB1 is in turn made of ROH3 and ROH4.

Strategy 74 is maintained for HALB1. For other materials, strategy group is not maintained. PIR is created for HALB1 (3 months – 100 pieces/month). MD02 for HALB1. Non convertible planned orders created for HALB1.

Now, PIR is created for FERT (same 3 months – 50 pieces/month). MD02 for FERT.

Independent requirements created for HALB1 are consumed based on the PIR of FERT and converted to DepReq of FERT.

and also...

3 convertible planned orders are created for HALB1. Could you please tell me why? I expected a convertible planned order to be created only after converting a planned order of FERT into a Production order.

I have attached the screenshots of FERT and HALB1.

Thank you very much for your time.

Thanks and regards,

Sethuraman Atisivan

    The consumption does not necessarily come from the production order of FERT as described in the sample scenario. In this case planned independent requirements for HALB are consumed by the dependent requirements coming from FERT. If you run MD73 for HALB you can see the details of the requirement and consumption quantities of HALB.

    I suppose when strategy 74 is used for HALB, additional and independently planning of demand for FERT is usually unexpected (that's why only production order is mentioned in the sample scenario).

    You create a demand program for HALB and procure its components regardless (in absence) of the demand for FERT. FERT is occasionally sold, which is reflected in the system by means of sales order and production order creation. This should trigger production of HALB, having procured the components you are able to gather the assembly at once, coping with the sales of FERT.

      Thank you very much for the reply. I have an unresolved issue regarding strategy 30. If you happen to get some free time, could you please have a look at it?

      By the way, may I know why this strategy is called as "Production by lot size"?

    As you are executing MRP (MD02) for the FERT material, BOM gets exploded which creates a reservation for its components. This inturn changes the order type of assembly planned orders and makes it convertible.

    The SAP help provides the following information regarding the necessary settings for this strategy:

    You must maintain the master data at the assembly level as follows:

    • Strategy group 74 on the MRP screen.
    • Set the indicator for assembly planning, the Mixed MRP indicator, to 3 on the MRP screen.
    • Consumption parameters (Consumption mode, Bwd consumption, Fwd consumption on the MRP screen) to allow for consumption of planned independent requirements.
    • If you are using this strategy in a make-to-stock environment, you also must set the Individual/coll. indicatorto 2 on the MRP screen.

    You must maintain the master data for the component of the assembly as follows:

    • Set the Individual/coll. indicator to 2 on the MRP screen.

    You must maintain a BOM for the assembly and its components.

      Good to hear from you Caetano. Thanks for the reply. Yes, I used that information from to work on the scenario I have posted above. I am not sure where I have went wrong.

      By the way, as the planning is done at assembly level for this strategy, I have left the 'strategy group' column blank in the MRP screen for FERT and the components of the assembly. Of course, the required settings has been done (as mentioned in your message) for the assembly and its components.
