• What is the cause and solution for SAP error message NP639 - Table of type & only allowed with data section < & ?

  The SAP error message NP639 indicates that there is an issue with the definition of a table type in your ABAP program or data dictionary. Specifically, it means that a table of a certain type is being used in a context where it is not allowed, typically related to the data section of a program or function module.
  Cause:
  The error occurs when:
  
  You are trying to use a table type that is not compatible with the context in which it is being used.
  The table type is defined in a way that it can only be used in a specific data section, but it is being referenced in a different context.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Table Type Definition: Review the definition of the table type in the ABAP Dictionary (SE11). Ensure that it is defined correctly and is intended for the context in which you are trying to use it.
  
  
  Context Verification: Ensure that you are using the table type in the correct context. For example, if the table type is defined for a specific data section, make sure you are not trying to use it in a different section (like a local class or method).
  
  
  Adjust Data Declaration: If you are declaring a table variable, ensure that you are using the correct type. You may need to change the type of the table variable to one that is compatible with the context.
  
  
  Check for Compatibility: If you are using a table type in a function module or method, ensure that the parameters are defined correctly and that the table type is allowed in that context.
  
  
  Consult Documentation: If you are unsure about the specific requirements for the table type, refer to the SAP documentation or help resources for guidance on how to define and use table types correctly.
