Dear SR,
I doubt thats possible, I tried to replicate the same thing and below is the result.
Deal created and posted through TBB1. Note the document number:100000509
I reversed the same it will generate new document which you can preview in S_ALR_87015216 - Money Market: Posting Overview
If you check the below document and click Reversal it will show the reversal document, Please go to table BSET and try to change the date.
I presume we have this option only or please write to SAP.
Regards,
Jain
