a particular material is not included in collective MRP run however it is included in single MRP run

[Former Member]

Hi All,

there is an issue currenlty faced by our client

there is one particular material which is not included in collective MRP whereas this is included when run at the material level.

1. i wanted to know is there any difference in customzing for material to differentiate between collective MRP run and  single MRP run.

2. is there any t code to check the lists of material included in collective MRP run.

I have checked from my end, i could find any difference between material included in collective MRP and material not included in collective MRP run.

Hi Anjali,

could you please check and confirm, as you said you have excluded material from MRP, does that mean you have maintained MRP type "ND" in material master MRP 1 view, also please confirm if after MRP run planned orders and created for that material?

Hi Amit,

i did not exclude material from MRP. the material has MRP type VB and still it was not included in collective MRP run.

but when single MRP run was carried out, requistion was created for that material.

Hi

In case of Manual re order point MRP Type VB, SAP does not consider to generate the procurement proposal because of dependent requirements but  procurement is triggered when the sum of plant stock and firmed receipts falls below the re order point maintained in MRP views and when this falls below the re order point then it will be planned in MRP.

Dear Anjali,

Check if the User Exit related to MRP run is active(based on MRP controller/MRP type etc).

You can find out the same by checking if any value is set in the user exit key field in the variant that is

used to schedule the MRP run in T.code MDBT.

So as already suggested by our forum members, MD02/MD03 does not check the planning file entry

and during collective MRP in MD01/MDBT (except for processing key NEUPL), the system checks if a

planning file entry exists for the material.

Check and come back.

Hello Anjali

Either the planning file does not exist or the planning file flags were not checked for this material.

If the planning file entry does not exist, you may run transaction MDAB, in order to create all the missing planning file entries.

If the planning file flags were not checked it's because there was no MRP relevant change for this material since the last MRP run. In this case, you may run MRP with key NEUPL, which selects all the materials for planning, despite the planning file flags.

Thanks Caetano for your reply.

I am new to PP and hence below query.

1. Is it mandatory to create planning file before any MRP run or it is created automatically?

2. how and when is the planning file flags are checked?

Regards,

Anjali

Hello

The planning file entry is created automatically when the MRP tabs are created and an MRP type, such as PD is set. In some cases, generally when materials are created by custom programs, the planning file is not created automatically. In such cases, transaction MDAB can be executed to create the planning file entry.

Once the planning file entry is created, the flags NETCH and NETPL are set for each MRP relevant change. That means, if you post a good movement, if you create a sales order, if you create a production order...

Setting those flags means that this material will be included on the next MRP run with the respective key NETCH or NETPL.

Hi Caetano,

this means if the planning file was not created, it should not have in included in single MRP run.

Thing is that particular mat is included in single MRP run but not in collective MRP run.

Anjali,

If by 'single MRP run' you mean MD03, this transaction ignores the planning file.  Lack of a planning file entry will not prevent this transaction from completing successfully.

Hello,

Please check the low-level code of the material in transaction MD21, and compare it with its upper-level material in BOM hierarchy. Lower level materials in BOMs must have higher low-level codes for MRP to process them in order with other materials. Due to recursive BOMs and order of editing BOMs sometimes inconsistencies occur in low-level codes.

If this is the reason, you may search for SAP notes for low-level codes. There are some correction programs for these inconsistencies. Low-level codes are calculated when BOMs are updated, therefore deletion and addition of the components may also correct the low-level codes.

Regards.

Hi

Check in MD21 for the same material whether planning file entries are generated for NETCH/NETPL or not, a material in involved in MRP when only these planning files are generated whether it is collective or single item MRP run

Hi,

1. There is no difference in customizing for material to differentiate between collective MRP run and  single MRP run.

2. Goto MD05, click on Collective access tab.

then enter the plant, MRP Controller or product group or vendor, MRP type give current date if you run it today.

then enter.

You will get material list. You can copy or extract material list to excel.

then put these materials in transaction COOIS with current date, now u will get last MRP Run planned order list.

Hi Anjali,

Your question is not very clear, However I can suggest some options.

• If you are using Scope of planning in MD01 check the setting first.
• Check the Materials has got any demands.
• Check the MRP area in Material Master.
• Using T-code OMOE, You can check the settings of your Scope of planning.
• Scope of Planning can be classified against MRP Areas. May be that particular Material's MRP Area are not in your defined Scope of planning.

Kind regards,
