Requirements grouping across several projects

[Former Member]

Hi,

We have a case where raw material requirements across several projects , have to be grouped together and MRP has to be run for genarating PRs.

1. What are the transactional steps involved?(A brief desc would do)

2. What are the config steps involved ? ( a brief desc would do)

3. Does someone has an example in the form of business process procedure ? Can it be shared with me (email ID : manohar84@rediffmail.com)

4. Which MRP needs to be run ? (PP-MRP / MM-MRP)

Thanks and regards,

Hi Manohar,

You need to use Grouping WBSE functionality in order to group several material requirments from various projects. Please refer following steps.

1. Activate grouping WBSE indicator for the WBSE where all requirments will be grouped.

2. In transactions GRM4 / GRM3, WBSE will be assigned for grouping purpose.

3. Grouping will happen based on MRP group of materials master.

4. Activate MRP Groups for Requirements Grouping. The path is PS->Material>Procurment-->Activate MRP Groups for Requirements Grouping

You can do MRP run at project level (MD51)

Hope this willl help you.

Hi Rakesh,

Thanks for the reply.

Please clarify whether we have to create new WBSs for grouping purposes based on MRP groups?

Hi Manohar,

New WBSE for grouping purpose can be created & depend on the business process also. Generally one WBSE will be there for material procurment in which all bought-out items will be procured. In some cases one project exclusively for material purchase also created which will group all material requirments for various projects.

Hope this will help you.

Hi Rakesh,

I have created a new project for grouping.I have assigned MRP cat 2 in this project.

I have assigned MRP category 2 in two other projects.

I have activated grouping requirements for MRP group in customizing.

When I run GRM3 , I am getting an error and am not able to assign to the grouping wbs.

Please advise if there is something wrong.

Thanks,

Hi,

You need to select grouping WBSE and select 1(Grouping WBS element for all materials). This will group all the material requirments from various projects.

Hope this will help you.

Hi Rakesh,

I have selected automatic grouping and grouping wbs is set to 2 in prj A1.

I have selected automatic grouping and grouping wbs is set to 2 in prj A2.

I have created a grouping wbs with automatic grouping and grouping wbs is set to 2 in prj-A

I have been able to assign the wbss to grouping wbs using GRM3.

When I run MD51 , it says " no elements exist for this selection" and "no reservations relevant for MRP exist for the project".

What could be wrong in the settings?

Please help.

Thanks,

Is the WBS element released? If not, goto Edit->Status->Release.

Hi,

Please check for the MRP type & Lot size, maintained in material master. It shud be of periodic lot size.

Also check the selection parameters of MD51. Select 'With heirarchy' also.

Thanks

Hi Manohar,

It seems the issue is due to material master. Please check the material master the MRP type & lot size as these are reasons for grouping of material requirments. In each material master, proper MRP type has to be defined as grouping will happen based on this. Lot size shoould be monthly.

Hope this will help you. Please let us know if you need any other details.

I was able to run MRP successfully.

One question that remains , is how do we handle budget in the grouping wbs?

Thanks,

Hi,

System checks for the budget availability of the each WBS Element to which the activity is assigned at the time of issuing the material from project stock to reservation/activity. Till then project stock will be shown with the grouping WBS Element.

Hi Manohar,

Budget will be consumed for materials from Grouping WBSE. You need to assign budget to WBSE where all material requirments will be grouped.

Hope this will help you.
