The SAP error message IDCFMHU_R01226 indicates that there is an issue with the availability of a certain value in the system. Specifically, the message states that the nominal value you are trying to lock (indicated by &1 and &3) is greater than the available value (indicated by &2 and &3). This typically occurs in scenarios involving inventory management, material management, or financial transactions where certain values need to be locked for processing.
Cause: Insufficient Available Quantity: The nominal value you are trying to lock exceeds the quantity that is currently available in the system. This can happen if there are discrepancies in inventory levels or if other transactions have already consumed the available quantity. Data Entry Error: There may be a mistake in the data entry where the nominal value was incorrectly inputted. Timing Issues: If multiple transactions are being processed simultaneously, one transaction may lock the available quantity before another transaction can access
