I have several hundred measurement documents all same time/date all easily collected in a list in various T-codes. However I don't see any basic/clear way of doing mass cancellation and only able to go through each Doc individually and doing Reversal Indicator > Set. It would be time consuming to cancel one at a time. Although I accept that it will probably turn out that this is the only approach.
(I am relatively new to the SAP but I get the impression my SAPs functionality is very limited. I have IK12, IK18 and the odd couple other T-Codes but I believe that is all and so won't be able to do any scripts that I have read about).
My apologies if I have put this question in the wrong area.
