Hi
need to maintain status profile name for those old documents in CRM_JSTO table. and modify the user status entry in CRM_JEST table. it should solve your issue.
Kapil is correct. The same issue occurs when you change status in the user status profile too as the E000* is assigned by the system like GUID.
About Kapil 1, I do not think you will be able to use the old document because system will check status profile and status and raises error.
About 2, it may not work if you have huge amount of old documents. My solution has the same problem. So perhaps a report is necessary for this necessary.
About 3, I think my solution simply specifies yours.
If you and Kapil find anything wrong of my solution or explanation, kindly let me know and let's learn together.
Thank you.
