Hi @Himasri ,
I assume there is a collection:
ClearCollect(
CollectionName,
{Product:"Abc",Quantity:1,'Okt-23':0,'Nov-23':0,'Dez-23':0,'Jan-24':1,'Feb-24':0,'Mar-24':0},
{Product:"Xyz",Quantity:3,'Okt-23':0,'Nov-23':0,'Dez-23':0,'Jan-24':2,'Feb-24':1,'Mar-24':0},
{Product:"Pqr",Quantity:2,'Okt-23':0,'Nov-23':0,'Dez-23':0,'Jan-24':1,'Feb-24':0,'Mar-24':1},
{Product:"Lmn",Quantity:3,'Okt-23':0,'Nov-23':0,'Dez-23':1,'Jan-24':1,'Feb-24':1,'Mar-24':0}
);
Please try this formula to submit records,
ForAll(
CollectionName,
If('Okt-23'>0,Collect(YourSPList,{Product:Product,Quantity:'Okt-23',Month:"Okt-23"}));
If('Nov-23'>0,Collect(YourSPList,{Product:Product,Quantity:'Nov-23',Month:"Nov-23"}));
If('Dez-23'>0,Collect(YourSPList,{Product:Product,Quantity:'Dez-23',Month:"Dez-23"}));
If('Jan-24'>0,Collect(YourSPList,{Product:Product,Quantity:'Jan-24',Month:"Jan-24"}));
If('Feb-24'>0,Collect(YourSPList,{Product:Product,Quantity:'Feb-24',Month:"Feb-24"}));
If('Mar-24'>0,Collect(YourSPList,{Product:Product,Quantity:'Mar-24',Month:"Mar-24"}))
)

Best Regards,
