C1305 - Details

• The SAP error message C1305, which states "Length of exponent must be 4. Example: E-__," typically occurs when dealing with numeric fields that require a specific format for scientific notation. This error is often encountered in contexts where floating-point numbers are being processed, such as in data imports, exports, or calculations.
  
  Cause:
  The error arises when the exponent part of a number in scientific notation does not conform to the expected format. In SAP, the exponent must be exactly four characters long, which includes the letter 'E' or 'e', the sign (either '+' or '-'), and the two-digit exponent value. For example, a valid exponent would look like E+01 or E-10. If the exponent is shorter or longer than this, or if it does not follow the correct format, the error will be triggered.
  
  Solution:
  To resolve this error, you should ensure that any numeric values being processed conform to the required format. Here
