• What is the cause and solution for SAP error message RAP_DSP_TABLE_MSG012 - too many long fields (LCHR, LRAW) ?

  The SAP error message RAP_DSP_TABLE_MSG012 indicates that there are too many long fields (LCHR, LRAW) in a data structure or table definition. This error typically arises in the context of the RAP (Rapid Application Programming) model, which is used for developing applications in SAP S/4HANA.
  Cause:
  The error occurs when the number of long fields (LCHR or LRAW) exceeds the allowed limit in a table or structure. Long fields are used to store large amounts of data, such as text or binary data, and there are restrictions on how many of these fields can be included in a single table or structure due to performance and memory considerations.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Reduce the Number of Long Fields:
  
  Review the data model and see if you can reduce the number of long fields in the structure or table. This may involve:
  
  Combining fields where possible.
  Storing some data in a separate table or structure.
  Using shorter data types for fields that do not require long field types.
  
  
  
  
  
  Refactor the Data Model:
  
  If the data model is complex, consider refactoring it to separate long text or binary data into different entities or tables. This can help in managing the data more efficiently and avoid hitting the limits.
  
  
  
  Use Alternative Data Types:
  
  If applicable, consider using alternative data types that do not fall under the long field category. For example, if you are using LCHR for large text, see if you can use a standard CHAR or STRING type with a reasonable length.
  
  
  
  Check SAP Notes:
  
  Look for any relevant SAP Notes or documentation that may provide additional guidance or updates related to this error. SAP frequently updates its systems, and there may be specific recommendations or patches available.
  
  
  
  Consult SAP Support:
  
  If you are unable to resolve the issue on your own, consider reaching out to SAP Support for assistance. They can provide insights based on the specific context of your application and data model.
