Hi Swagat,
Can you please check the material master and the storage type search strategy
1) system first look at the material master WM1 view, picks the value of stock removal
2) Pass the value to storage type search and find the corresponding entry from LE--WM---Strtegies--storage type search,---Determin search sequence (check whether storage type search entry exist for the selected Removal indicator and movement type if any reference is defined in WM movement type or not)
