• What is the cause and solution for SAP error message 32230 - ALV list: field catalog entries (GT_FIELDCAT) greater than 99 ?

  The SAP error message 32230, which states "ALV list: field catalog entries (GT_FIELDCAT) greater than 99," typically occurs when you are trying to display an ALV (ABAP List Viewer) report and the number of field catalog entries exceeds the limit of 99. The field catalog is a data structure that defines the properties of the fields to be displayed in the ALV output.
  Cause:
  The primary cause of this error is that the internal table used for the field catalog (GT_FIELDCAT) has more than 99 entries. This limit is imposed by the ALV function modules, which restrict the number of fields that can be displayed in a single ALV report.
  Solution:
  To resolve this issue, you can consider the following approaches:
  
  
  Reduce the Number of Fields: Review the fields you are including in the ALV output. If possible, limit the number of fields to 99 or fewer. This may involve removing some fields from the field catalog or consolidating data.
  
  
  Split the ALV Output: If you need to display more than 99 fields, consider splitting the output into multiple ALV reports. Each report can handle a subset of the fields, ensuring that each individual report adheres to the 99-field limit.
  
  
  Use Multiple ALV Grids: If your application allows, you can create multiple ALV grids on the same screen, each with its own field catalog. This way, you can display more than 99 fields across different grids.
  
  
  Dynamic Field Catalog: If you are dynamically generating the field catalog, ensure that your logic correctly limits the number of fields added to the catalog.
  
  
  Related Information:
  
  ALV Function Modules: Familiarize yourself with the ALV function modules you are using, such as REUSE_ALV_GRID_DISPLAY or REUSE_ALV_LIST_DISPLAY, as they have specific parameters and limitations.
  Field Catalog Structure: Understand the structure of the field catalog (e.g., LVC_S_FCAT) and how to define it properly to avoid exceeding the limit.
  Performance Considerations: While it may be tempting to include many fields, consider the performance implications of displaying a large number of fields in an ALV report.
  
  By following these guidelines, you should be able to resolve the error and successfully display your ALV report.
