How To Fix QISR008 - Structure &1 contains a field from the "Table type" category (TTYP)

SAP Error Message - Details

• Message type: E = Error

• Message class: QISR - Internal Service Requests

• Message number: 008

• Message text: Structure &1 contains a field from the "Table type" category (TTYP)

What causes this issue?

You entered structure &V1& as a dictionary reference. This structure
contains a table type field. You can only use flat structures, and so
the structure you entered cannot be used.

How to fix this error?

Choose a data element or a flat structure as a dictionary reference.
Alternatively you can create an uncategorized field or a field that
refers to a classification characteristic.

• What is the cause and solution for SAP error message QISR008 - Structure &1 contains a field from the "Table type" category (TTYP) ?

  The SAP error message QISR008 indicates that there is an issue with a structure in your ABAP program or data dictionary that contains a field from the "Table type" category (TTYP). This typically occurs when you are trying to use a structure that is not compatible with the expected data type in a certain context, such as when passing data to a function module or method that expects a different type of data.
  Cause:
  
  Incompatible Data Types: The structure you are using contains fields that are defined as table types, which are not allowed in certain contexts where a simple data type or a structure is expected.
  Incorrect Definition: The structure may have been incorrectly defined in the data dictionary, leading to the inclusion of table-type fields.
  Usage in Function Modules: If you are trying to pass this structure to a function module or method that does not accept table types, this error will occur.
  
  Solution:
  
  
  Review Structure Definition: Check the definition of the structure in the ABAP Dictionary (SE11). Ensure that it does not contain any fields defined as table types (TTYP). If it does, consider changing those fields to a compatible type, such as a simple data type or a structure.
  
  
  Modify the Program: If the structure is being used in a program, ensure that you are not trying to pass it to a function module or method that expects a different type. You may need to create a new structure that only includes the necessary fields.
  
  
  Use Appropriate Data Types: If you need to work with table data, consider using internal tables instead of structures. You can define an internal table with the appropriate row type and use it where needed.
  
  
  Check Function Module Parameters: If you are calling a function module, check the parameters to ensure that you are passing the correct types. You may need to adjust the parameters or create a wrapper function that converts the data to the expected format.
  
  
  Related Information:
  
  ABAP Data Dictionary (SE11): Use this transaction to view and modify the definitions of structures, tables, and data elements.
  Function Module Documentation: Review the documentation for the function modules you are using to understand the expected data types for parameters.
  ABAP Development Guidelines: Familiarize yourself with best practices for defining data structures and types in ABAP to avoid similar issues in the future.
  
  By addressing the structure definition and ensuring compatibility with the expected data types, you should be able to resolve the QISR008 error.
