User Exit ZXMBCU02
We have used user exit ZXMBCU02 to avoid delivery note duplication while doing transaction MIGO.
In which user is not allowed to make duplicate entries for delivery note number i.e. if "xyz" delivery note number is used once, then it should not be allowed again in any financial year.
Now we want to allow the user to make duplicate delivery note entry if the delivery note no. is used in previous financial year. i.e. if delivery note no "abc" is used in FY 2014 it should be allowed to enter in FY 2015.
Kindly guide as what changes needs to be done in ZXMBCU02 or is there any other user exit for this requirement.
