here, this is the case, the pr have some different materials and also every PR has different IRS and for the IRS it may have same or different suppliercodes
in the above the suppliercode is same for a,b,f so create po 1 time instead of 3 times with x xupplier code
and c,e instead of 2 pos create 1 with y supplier code
for d create 1 po
if a,bc,d,e,f contains same suppliercode then create 6 different pos
