My fault, this approach was so wrong. I tried to use same procedure that I was used to on solman 7.01 and it became obsolete in solman 7.1.
Also in screenshot of my original post, you can see Change Request (Old), which truly was old type of crm transaction SDCR and urgent correction was SDHF...
In new solman7.1 there are similar transactions with names strating with SM... like SMHF. -those are the current ones.
also entry point is transaction SM_CRM or CRM_UI, not old CHARM_CREATE.
when using web ui, there is no such error (referring to my original question).
