(any table or index table) and a generic <DS:TX.DDDOC_KEYKIND>key
category</>. They can only be used to define the types of generic table
parameters of function modules and forms, but not to define data

• What is the cause and solution for SAP error message DO847 - Row type & is a generic table type ?

  The SAP error message DO847 indicates that there is an issue with the data type being used in a table or structure. Specifically, it states that the row type you are trying to use is a generic table type, which is not allowed in certain contexts.
  Cause:
  The error typically arises in the following scenarios:
  
  Generic Table Type Usage: You are trying to use a generic table type (like TABLE OF ANY TYPE) in a context where a specific table type is required.
  Data Declaration Issues: There may be a mismatch in the expected data type for a table or structure in your ABAP code.
  Function Module or Method Call: You might be passing a generic table type to a function module or method that expects a specific table type.
  
  Solution:
  To resolve the DO847 error, consider the following steps:
  
  
  Check Data Types: Ensure that you are using a specific table type rather than a generic one. If you are declaring a table, make sure it is defined with a specific structure.
  TYPES: BEGIN OF ty_my_structure,
           field1 TYPE string,
           field2 TYPE i,
         END OF ty_my_structure.
  
  DATA: lt_my_table TYPE TABLE OF ty_my_structure.
  
  
  Review Function Module/Method Signatures: If you are calling a function module or method, check the parameter types. Ensure that you are passing the correct type of table that the function/module expects.
  
  
  Use Specific Types: If you need to work with a generic table, consider defining a specific structure that meets your requirements and use that instead.
  
  
  Debugging: If you are unsure where the error is occurring, use the ABAP debugger to step through your code and identify where the generic table type is being used incorrectly.
  
  
  Consult Documentation: Review the SAP documentation for the specific function module or method you are using to understand the expected data types.
  
  
  Related Information:
  
  ABAP Data Types: Familiarize yourself with the different data types in ABAP, especially how to define and use structured types and internal tables.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to the DO847 error.
