    Hi @AnamikaDas-0462,

    The waring is incomplete, suppose that it tells you such as:

    Warning: Truncation may occur due to inserting data from data flow column "Acqxxx" with a length of 255 to database column "Acqxxx" with a length of 50.

    In order to remove this warning message from SSIS solution, make sure datatype length of the source column should be equal to the datatype length of the destination column.

    Change the destination column length to 255 for a try or change the data source length to 50.

    Regards，

    Zoe

    Truncation may occur

    That means you try to insert large data into a destination, then it's defined for the destination column.
    Your source is nvarchar with max size 255 and the destination column is smaller then 255 characters.

    Your screen prints indicated your target "Acquisition Item" is an nvarchar(50).

    As a default all fields from Excel are returned as nvarchar(255). The simplest answer is to use a data conversion to truncate the field to nvarchar(50) before the insert.
