SA with Independent Condition, Wrong GRIR entry

I am working with Scheduling agreement with Independent conditions

I removed the tick in front of my SA doc type in which was for time dependent,

Now I can see the pricing as per PO,

I maintained the Info records as follows,

P000=3.5

FRB1=200

I created SA for material which is having Std price,

with tax code 2% CST , and above conditions were flowing to pricing

But when I post GR , the GR/IR hitting with wrong amount,

dont know how system is calculating that amount

SA Price-3.5 ,SA QTY-100000 Nos

STD Price in MMR-3.69

After GR for 1300 qty entries were, purchase account management activated

Inventory -Wip         4797

Clearing GR/IR         5133.33

Price Dfife Pr Or      336.33

Purchase - Sm          4797    

Purchase- Offsetting   4797

Clearing Freight        2.6

Purchase - Freight      2.6

Please help me to understand the why GRIR hit with 5133.33

Thanks
