We deal in two products AA and LA. LA is obtained by diluting water and AA. For ex. we dilute 2000Kgs of AA with 6000 Kgs of Water and obtain 8000 Kgs of LA.

So there should be a provision/ a Form so that we are able to enter the two items and get the third item. All these items i.e. Water, AA and LA items have been created and we are allowed to only enter Opening Balance.
