Hello Vijesh,
What kind of requirement do you want to consider during the Re order base planning ?
If you want to consider the External requirement (Sales order Requirement), In that case you have to select the MRP type V1/V2, Make sure "External requirement" selected in customizing setting in OMDQ.
MRP type "VB" is Manual reorder planning and it will work at time of Material Stock fall below the Re order point qty set in material master.
In Re order based planning system not consider the Planning Strategy.
Please check the both condition from your end and update the same.
Thanks & Regards
Umesh Mali
