storage location issue
I have a issue related to storage location determination. There are three materials X,Y and Z. Material X is main item and Y, Z are components of X. While creating sales order when we enter X it explodes BOM. Now in customizing for material X and Z storage location has been determined as SL1 but for material Y SL2 is determined. When we create delivery system automatically proposes storage location for all materials as-
Material X- SL1
Material Y- SL1
Material Z- SL1
For material X and Z it should be SL1 (which is coming right) but for Material Y it should be SL2 (but its coming as SL1 automatically)
I've checked every area right from the combination of plant, shipping point and storage condition (storage condition is different in case of Material Y). There are also no stock determination rules defined in item category and material master. SL req. and determine SL is marked for item category of each line item.
Please help me with this issue
