How To Fix UCT8037 - Mapping rule for &1, row &2: MOVE is incorrect

SAP Error Message - Details

• Message type: E = Error

• Message class: UCT8 - Message class for UCT8(mapping)

• Message number: 037

• Message text: Mapping rule for &1, row &2: MOVE is incorrect

What causes this issue?

For each source field of an operator you can split the source into two
pairs of attributes: offset and length; separator and index.
The current values are invalid because they do not meet the following
requirements:
Offset and Length
When an "offset" is defined without a "length", the move operation is
valid. The system moves the part of the character string starting at the
offset position up to the end of the string.
When a "length" is defined without an "offset", the move operation is
valid. The system moves the part of the character string starting at the
first character up to the position designated by the "length" to the
target field.
When a value is specified for the "offset" or the "length" (or both),
then the "separator" and the "index" may not have any values. Otherwise,
the move operation is invalid.
The values must be numbers greater than zero.
Separator and Index
Both the "separator" and the "index" must contain values. The move
operation is invalid if only one of the attributes contains a value.
When the "separator" and the "index" contain values, you may not enter
values for the "offset" and "length". Otherwise, the move operation is
invalid.
The value for "index" must be a number greater than zero.

• What is the cause and solution for SAP error message UCT8037 - Mapping rule for &1, row &2: MOVE is incorrect ?

  The SAP error message UCT8037 indicates that there is an issue with a mapping rule in the context of data transfer or transformation, specifically when using the MOVE statement in a mapping rule. This error typically arises in the context of SAP Data Services or similar data transformation tools where data is being mapped from one structure to another.
  Cause:
  The error message "Mapping rule for &1, row &2: MOVE is incorrect" suggests that there is a problem with the syntax or logic of the MOVE statement in the mapping rule. Common causes include:
  
  Incorrect Data Types: The source and target fields may have incompatible data types. For example, trying to move a string into a numeric field without proper conversion.
  Field Length Issues: The length of the source field may exceed the length of the target field, leading to truncation or overflow errors.
  Invalid Field References: The field names used in the MOVE statement may be incorrect or not defined in the context of the mapping.
  Logical Errors: There may be logical errors in the mapping that do not conform to the expected data transformation rules.
  
  Solution:
  To resolve the UCT8037 error, you can take the following steps:
  
  
  Check Data Types: Ensure that the data types of the source and target fields are compatible. If necessary, use conversion functions to convert data types appropriately.
  
  
  Verify Field Lengths: Make sure that the length of the source field does not exceed the length of the target field. If it does, consider truncating the source data or increasing the target field length.
  
  
  Review Field Names: Double-check the field names used in the MOVE statement to ensure they are correct and exist in the mapping context.
  
  
  Examine Mapping Logic: Review the logic of the mapping rule to ensure it aligns with the intended data transformation. Look for any logical inconsistencies that may cause the MOVE statement to fail.
  
  
  Test with Sample Data: If possible, test the mapping rule with sample data to identify specific cases that trigger the error.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific syntax and usage guidelines related to the MOVE statement in the context of your SAP environment.
