How To Fix UC776 - Field types for characteristic &1 and sender field &2 are different

UC776 - Overview

• Message type: E = Error

• Message class: UC - FI/CO Data transfer: errors during transfer

• Message number: 776

• Message text: Field types for characteristic &1 and sender field &2 are different

What causes this issue?

You will see that problems can arise if sender fields are assigned to
receiver fields and the fields are of different types. Invalid values
could appear. Usually an ABAP command MOVE is carried out. This command
has a special logic for the type conversion and may not always be
suitable. See the ABAP documentation for the rules on type conversion.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If, for example, you wish to convert fields from data type N or C to
date fields, check first in a test run whether the results are correct.
Alternatively, you can set the fields in the sender structure to the
'correct' type. Then during an import, the system checks if the fields
have been filled correctly for their type.

  Cause:
  The error arises when:
  
  The data type of the characteristic (e.g., a key figure or attribute) does not match the data type of the sender field (e.g., a field from a data source or an InfoObject).
  For example, if the characteristic is defined as a numeric type and the sender field is defined as a character type, this mismatch will trigger the error.
