Activating MRP in SAP HANA

Dear SAP Friends,

This Blog is a continuation to my previous blog on MRP Live on SAP S/4 HANA 

So in this Blog, we will be seeing how to activate classic MRP for the materials.

Once we maintain PD or other MRP Types except VB Reorder point Planning System will automatically Activate MRP Live for those materials

If due to some other Business requirements if MRP Live plan need to be changed to Classic MRP means need to follow Below Steps

1. Go to MD_MRP_FORCE_CLASSIC Transaction Code

Give the parameters as per requirement.

In this report, the system displays all materials with active MRP views in the material master and we can define that the planning run is to be executed using classic MRP for individual materials. we should check which materials require the processing of a BAdI during the MRP run and always set this indicator for these materials.

2. Once Executed report will be opened with Below Information’s like

• Material
• MRP Controller
• Plant
• MRP Area
• Information from Last MRP Live on HANA Run
• Source of Issue
• Time Stamp

3. Switch from Display mode to Change Mode and we can see Classic MRP

Select the material which needs to be planned in Classic MRP and save

We use this report for the following reasons:

If we want to include as many materials as possible in the MRP Live on HANA run, this report provides we with information on the restriction that prevents material from being included in MRP Live on HANA. In the report, we can navigate to the following screen where we can change the material in a way that avoids the feature that is not supported by MRP Live on HANA. If no standard solution exists that can solve the issue, the system displays an appropriate message.

We always want the system to call classic MRP instead of MRP Live on HANA to plan certain materials in certain plants. This means, for example, that we can further improve the performance of MRP Live on HANA by setting the materials that we know cannot be planned in the MRP Live on HANA run – due to a restriction – to be planned in classic MRP. If we have made the appropriate setting here, the system automatically plans the material using the classic MRP logic in the next planning run. Note that we should make this setting for materials that require changes in the planning logic in BAdIs. These materials must be planned in classic MRP. Therefore, check which materials require the processing of a BAdI during the MRP run and set the Always Plan in Classic MRPindicator for these materials.

We also use this report to determine whether a material is to be displayed in the apps for Material Requirements Planning. This information is automatically checked by the system the first time we access the apps and is saved in the field, Material Displayed in MRP Apps. If we manually change the master data of material so that it is included in MRP Live on HANA, we can also instruct the system to recheck whether the changes we have made means that the material is now automatically displayed in the MRP apps. To do so, select the materials that we want to recheck and choose Display in MRP Apps: Recheck

We can Select Multiple Materials and perform Select / Deselect for Classic MRP.
