The SAP error message COWIPB221, which states "Internal batch number assignment not possible in 'Goods Receipt' area," typically occurs during the goods receipt process when the system is unable to assign a batch number to the material being received. This can happen for several reasons, and understanding the cause is essential for finding a solution. Causes: Batch Management Configuration: The material may not be properly configured for batch management. If the material is set to use batch management but the batch number assignment settings are incorrect, this error can occur. Batch Number Range Issues: The batch number range may not be defined or may be exhausted. If there are no available batch numbers in the defined range, the system cannot assign a new batch number. Batch Status: The batch status may not allow for new assignments. For example, if the batch is marked as "restricted" or "blocked," it cannot be assigned to new goods
