Dear Experts,

Request your valuable guidance on the below point noted in the SAP note 2268120 - S4TWL - Digital Signature on conversion. ( presently we are in the task of ECC 1605 Simple Fin. to 1909)

- "Required and Recommended Action(s)

Check before the upgrade that all open signature processes are completed. This is generally relevant for all signature processes, independent of the signature functionality used (legacy or class-based signature tool)"

With the above Required & Recommended action , is it necessary to clear all open Inspection Lots with Digital signatures

( Results & UD / wherever applicable ?), then only conversion step will be successful?.

Requesting your review and valuable guidance on above point.

Thanks & Regards,
