SINGLE BATCH SCALLING ISSUE

I NEED TO CREATE PRODUCT AND CO PRODUCTS IN SINGLE BATCH AND BOTH PRODUCT INGREDIENTS ARE DIFFERENT . SO, I HAVE ADDED FORMULA PRODUCT TAB PRODUCT AND CO PRODUCT , THEIR INGREDIENTS. IN RECEIPE I HAVE ENTERD STEP QUANTITY WHICH INGREDIENTS WANT TO GO WHICH STEP. WHEN I AM DOING SCALLING IN BATCH , BOTH PRODUCT INGREDIENTA AND QUANTITIES ARE CHANGING. I NEED TO SCALE UP ONLY FOR PRODUCT ,SO I HAVE ENTERED RECEIPE'S STEP QUANTITY YIELD PERCENTAGE 75% AND 25% ACCORDING WANT TO PRODUCT. I HAVE ENABLED CALCULATE STEP QUANTITY. AFTER COMPLETE THIS I CREATED BATCH STILL SCALUP HAPPENING FOR BOTH.(E.G :IF I ENTERED 100 SCALE UP FOR PRODUCT , CO PRODUCT ALSO CHANGING AND INGREDIENTS.
