SAP Error Message - Details

• Message type: E = Error

• Message class: RS_HCPR_MODEL - Messages related to the HANA Composite Provider Backend

• Message number: 087

• Message text: Precision or scale of target field '&2' is too small

What causes this issue?

Source field '&SYST-MSGV1&' has higher a precision or scale than the
assigned target field '&SYST-MSGV2&'.
This might lead to number overflows.

• What is the cause and solution for SAP error message RS_HCPR_MODEL087 - Precision or scale of target field '&2' is too small ?

  The SAP error message RS_HCPR_MODEL087 indicates that there is an issue with the precision or scale of a target field in a data model or transformation. This typically occurs when you are trying to load data into a target field that cannot accommodate the values being inserted due to its defined precision (the total number of digits) or scale (the number of digits to the right of the decimal point).
  Cause:
  
  Data Type Mismatch: The target field in the database or data model has a smaller precision or scale than the source field from which data is being loaded.
  Data Overflow: The values being loaded exceed the maximum allowable size for the target field.
  Transformation Logic: If there are transformations applied to the data (e.g., calculations, concatenations), they may result in values that exceed the target field's limits.
  
  Solution:
  
  
  Check Target Field Definition: Review the definition of the target field in the database or data model. Ensure that its precision and scale are sufficient to accommodate the incoming data.
  
  For example, if the target field is defined as DECIMAL(5,2), it can hold values from -999.99 to 999.99. If you try to load a value like 1000.00, it will trigger this error.
  
  
  
  Adjust Data Model: If necessary, modify the target field to increase its precision or scale. This can be done through the database schema or data model configuration.
  
  
  Review Source Data: Check the source data to ensure that it does not contain values that exceed the limits of the target field. If it does, you may need to clean or transform the data before loading it.
  
  
  Modify Transformation Logic: If transformations are causing the issue, adjust the logic to ensure that the resulting values fit within the target field's constraints.
  
  
  Testing: After making changes, test the data load process again to ensure that the error is resolved.
  
  
  Related Information:
  
  Data Types in SAP: Familiarize yourself with the different data types and their precision/scale settings in SAP, especially if you are working with ABAP or BW.
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error message.
  Documentation: Review SAP documentation on data modeling and ETL processes to understand best practices for defining field types and handling data loads.
  
  By addressing the precision and scale issues, you should be able to resolve the RS_HCPR_MODEL087 error and successfully load your data.
