Smart SAP Assistant

• What is the cause and solution for SAP error message RS_HCPR_MODEL074 - Source field '&1' and target field '&2' do not have compatible data types ?

  The SAP error message RS_HCPR_MODEL074 indicates that there is a mismatch in data types between a source field and a target field during a data transfer or transformation process, typically in the context of data modeling or data extraction in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  This error occurs when:
  
  The source field and target field are defined with different data types (e.g., one is a string and the other is an integer).
  There is an attempt to map or transfer data from a source field to a target field where the data types are incompatible.
  The data model or transformation logic is incorrectly defined, leading to mismatched data types.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Data Types: 
  
  Review the data types of both the source field (&1) and the target field (&2). Ensure that they are compatible. For example, if the source is a string, the target should also be a string or a compatible type.
  
  
  
  Modify Data Types:
  
  If possible, modify the data type of either the source or target field to ensure compatibility. This may involve changing the data type in the data model or transformation settings.
  
  
  
  Transformation Logic:
  
  If you are using a transformation, check the transformation rules. Ensure that any mappings or calculations are correctly defined to handle the data types appropriately.
  
  
  
  Data Type Conversion:
  
  If changing the data types is not feasible, consider implementing a data type conversion in the transformation logic. For example, you can use functions to convert data types explicitly.
  
  
  
  Testing:
  
  After making changes, test the data transfer or transformation process again to ensure that the error is resolved.
  
  
  
  Documentation:
  
  Document any changes made to the data model or transformation logic for future reference and to assist other team members.
