• What is the cause and solution for SAP error message RSDL055 - Field &1 has received no suitable DDIC type ?

  The SAP error message RSDL055 indicates that a field in your data source does not have a suitable Data Dictionary (DDIC) type associated with it. This typically occurs in the context of SAP BW (Business Warehouse) or when working with data sources in SAP systems.
  Cause:
  
  Missing DDIC Type: The field in question may not have a corresponding Data Dictionary type defined in the SAP system. This can happen if the field is newly created or if there are inconsistencies in the data source definition.
  Incorrect Field Mapping: The field may be incorrectly mapped or defined in the data source, leading to the system being unable to identify a suitable DDIC type.
  Data Source Configuration: The data source may not be properly configured, or there may be issues with the underlying table or structure from which the data is being extracted.
  
  Solution:
  
  Check Field Definition: Verify the field definition in the data source. Ensure that the field is correctly defined and that it has a corresponding DDIC type.
  Update Data Source: If the field is newly added or modified, you may need to refresh or update the data source in the BW system. This can be done by:

  Selecting the option to "Update" or "Activate" the data source.
  
  
  Check Data Source Mapping: Ensure that the mapping of fields in the data source to the target InfoObject or data model is correct. You may need to adjust the mapping if there are discrepancies.
  Consult DDIC: If you have access, check the Data Dictionary (transaction SE11) to see if the field is defined and has a suitable type. If it is missing, you may need to create or modify the DDIC type.
