What alpha numeric character is placed in position 9 of the procurement instrument identifier when issuing an amendment?

In a procurement instrument identifier, the alpha numeric character in position 9 is used to denote specific characteristics of the document, such as whether it is an amendment. For amendments, the letter "R" is designated in this position. This convention provides a standard way to identify the status of the procurement instrument quickly. The use of "R" signifies that the document has been modified or updated, indicating to all parties involved that they are dealing with an amended version of the original procurement document. This clarity is crucial in contract management and helps maintain organized records within the procurement process.
