• What is the cause and solution for SAP error message FDT_EXPRESSIONS552 - Delimiter cannot be null ?

  The SAP error message FDT_EXPRESSIONS552: Delimiter cannot be null typically occurs in the context of using the SAP Fiori or SAP S/4HANA applications that involve data transformation or expression evaluation, particularly when working with field-based expressions or data manipulation.
  Cause:
  The error indicates that a delimiter, which is expected to separate values in a string or list, is not provided (i.e., it is null). This can happen in scenarios such as:
  
  Data Transformation: When trying to split a string into multiple parts using a delimiter, if the delimiter is not specified, the system cannot perform the operation.
  Expression Evaluation: In expressions where a delimiter is required for functions like SPLIT, CONCATENATE, or similar, if the delimiter is missing, the error will be triggered.
  Configuration Issues: Incorrect configuration in the data model or transformation logic where delimiters are expected but not defined.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Expression: Review the expression or transformation logic where the error occurs. Ensure that all functions requiring a delimiter have a valid, non-null delimiter specified.
  
  
  Provide a Default Delimiter: If the delimiter is optional, consider providing a default value to avoid null situations.
  
  
  Debugging: Use debugging tools available in SAP to trace the execution and identify where the null delimiter is being passed. This can help pinpoint the exact location in the code or configuration.
  
  
  Review Data Sources: Ensure that the data sources being used do not have null or empty values that could lead to this error when processed.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for the specific function or expression you are using to understand the expected parameters and their requirements.
  
  
  Testing: After making changes, test the expression or transformation to ensure that the error is resolved and that the expected output is achieved.
