Calculated Measures is creating duplicate rows for each unique part number

[a22430112]

MRP table is my Master Sheetwhich which is using "Part Number" as primary to find the attributes in other two tables. 

When creating a new measure "MOH" to calculate the inventory on hand status, I used the formula below. 

All of the items like the example below where the first line calculates correctly, but it is generating hundreds of duplicated lines with the incorrect "description" and "Item Sub-family". 

Those two attributes were pulled from different table. Only the first line seem to have the correct info. 

Could someone please help ?

@a22430112 , i think that is because of isblank,use simaple divide

or

divide([A],[B], 999)

isblank or +0 etc froce a complete left join on dimension and all the values will be shown
