How To Fix GS762 - Formula result cannot be converted into the type of the table field

SAP Error Message - Details

• Message type: E = Error

• Message class: GS - Sets

• Message number: 762

• Message text: Formula result cannot be converted into the type of the table field

What causes this issue?

The formula result of variable &V1& cannot be converted into the type
of the table field.

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 the error occurred in variable maintenance and variable &V1&
contains other variables, the default values were used to evaluate the
formula. Other values might give a valid result.
If no variables were used in the formula or the variables used have
meaningful default values, change the formula.
If the error occurred when executing the report, change the values of
variables on the selection screen.

• What is the cause and solution for SAP error message GS762 - Formula result cannot be converted into the type of the table field ?

  The SAP error message GS762, which states "Formula result cannot be converted into the type of the table field," typically occurs in the context of SAP ABAP programming, particularly when working with internal tables and field-symbols. This error indicates that there is a type mismatch between the result of a formula or calculation and the expected data type of a field in a table.
  Causes:
  
  Data Type Mismatch: The most common cause is that the result of a formula or calculation does not match the data type of the field in the internal table. For example, trying to assign a string value to a numeric field.
  Field Length Issues: If the length of the result exceeds the defined length of the field in the internal table, this error can occur.
  Incompatible Data Types: Using incompatible data types in operations, such as trying to perform arithmetic operations on character fields.
  Incorrect Field Assignment: Assigning a value to a field that is not compatible with the expected data type of that field.
  
  Solutions:
  
  
  Check Data Types: Review the data types of the fields involved in the formula and ensure they are compatible. Use the appropriate data type conversions if necessary.
  
  For example, if you are trying to assign a numeric result to a character field, you may need to convert the numeric value to a string using CONCATENATE or WRITE statements.
  
  
  
  Use Type Conversion Functions: Utilize SAP's built-in type conversion functions such as CONVERT_TO_STRING, CONVERT_TO_INTEGER, etc., to ensure that the data types match.
  
  
  Adjust Field Lengths: If the result of the formula is too long for the target field, consider increasing the length of the field in the internal table or truncating the result appropriately.
  
  
  Debugging: Use the debugger to step through the code and inspect the values and types of the variables involved in the assignment. This can help identify where the mismatch occurs.
  
  
  Check Formula Logic: Ensure that the logic of the formula is correct and that it produces a result that is expected and compatible with the target field.
  
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the various data types in ABAP, such as CHAR, NUMC, DATS, TIMS, etc., and their characteristics.
  Internal Tables: Understand how internal tables work in ABAP, including how to define them and how to manipulate their contents.
  Type Conversion: Review the documentation on type conversion in ABAP to understand how to properly convert between different data types.
  
  By addressing the above points, you should be able to resolve the GS762 error and ensure that your formula results are compatible with the expected data types in your SAP program.
